How to improve fingerprint recognition with touch id

Learn how to set up and use Touch ID, a fingerprint identity sensor that makes it easy for you to get into your device.

Set up Touch ID

Where is the Touch ID sensor?

The Touch ID sensor is either in the Home button or—on iPad Air (4th generation)—the top button. When you follow the steps below, the onscreen instructions will tell you which button to use.

Set up Touch ID

Before you can set up Touch ID, you need to create a passcode for your device.* Then follow these steps:

  1. Make sure that the Touch ID sensor and your finger are clean and dry.
  2. Tap Settings > Touch ID & Passcode, then enter your passcode.
  3. Tap Add a Fingerprint and hold your device as you normally would when touching the Touch ID sensor.
  4. Touch the Touch ID sensor with your finger—but don’t press. Hold it there until you feel a quick vibration, or until you’re asked to lift your finger.

Make purchases with Touch ID

You can use Touch ID instead of your Apple ID password to make purchases in the iTunes Store, App Store, and Apple Books. Just follow these steps:

  1. Make sure iTunes & App Store is turned on under Settings > Touch ID & Passcode. If you can’t turn it on, you might need to sign in with your Apple ID in Settings > iTunes & App Store.
  2. Open the iTunes Store, App Store, or Apple Books.
  3. Tap something to buy. You’ll see a Touch ID prompt.
  4. To make a purchase, lightly touch the Touch ID sensor.

Use Touch ID for Apple Pay

With an iPhone 6 or iPhone 6 Plus or later, you can use Touch ID to make Apple Pay purchases in stores, within apps, and on websites in Safari. You can also use Touch ID on your iPhone to complete website purchases from your Mac. If you have an iPad Pro, iPad Air 2 or iPad Mini 3 or later, you can use Touch ID for Apple Pay purchases within apps and on websites in Safari.

Manage your Touch ID settings

Go to Settings > Touch ID & Passcode to manage these settings:

  • Turn Touch ID on or off for Passcode, iTunes & App Store, or Apple Pay.
  • Enroll up to five fingerprints. Each new print might make fingerprint recognition take slightly longer.
  • Tap a fingerprint to rename it.
  • Swipe to delete a fingerprint.
  • Identify a fingerprint in the list by touching the Touch ID sensor. The matching print in the list will be highlighted briefly.

Press the Touch ID sensor using Touch ID to unlock your device. To unlock your device using Touch ID without pressing the Touch ID sensor, go to Settings > Accessibility > Home Button [or top button] and turn on Rest Finger to Open.

How to improve fingerprint recognition with touch id

Fingerprint readers on phones have made devices more secure and faster to unlock, at least when they work on the first try. If you have trouble unlocking your phone quickly, there are things you can do to improve your device’s fingerprint reader.

Biometric identification on phones has come a long way over the last few years, with both Apple and Google building APIs to bring fingerprint scanning to the masses on their respective platforms. While the early versions were good enough to use, the later versions have gotten even better—but they’re still not perfect.

There are certain situations where fingerprint readers simply aren’t as accurate, but there are a handful of things you can do to fix this. With the right tweaks, you can achieve 100 percent first-try accuracy from your phone’s fingerprint reader.

You’ll need to access your phone’s fingerprint settings for all of these. Here’s where you’ll find them:

  • iOS: Settings > Touch ID & Passcode > Fingerprints
  • Android: Settings > Security > Device/Phone Security

Depending on your Android phone model, you may have to look around a little bit to find the exact name of the fingerprint setting. On Pixel phones, it’s called Pixel Imprint. On Samsung Galaxy devices, it’s just labeled as “Fingerprint Scanner.”

Register the Same Finger More Than Once for Improved Accuracy

How to improve fingerprint recognition with touch id

This is one of those tips that’s so simple, yet not completely obvious. If you generally unlock your phone with the same finger and find that it doesn’t work on the first try some of the time, just register that finger a second time. Both Android and iOS let you register multiple fingerprints, and there’s no rule that says they can’t be for the same finger.

While the system sees it as a “new” fingerprint, it will simply improve accuracy from that one finger. The odds are you won’t have to add it more than once, and the accuracy will be dramatically improved.

Register Both Hands for Unlocking in Any Situation

How to improve fingerprint recognition with touch id

It may seem obvious, but you should register fingers on both hands. This way, if the hand you generally unlock your phone with is tied up, you can still unlock your phone easily with the other one. Similarly, it’s probably a good idea to register multiple fingers on each hand.

Also, go ahead and register all additional fingers a couple of times too. You know, for accuracy.

Add A Fingerprint Right Out of the Shower

How to improve fingerprint recognition with touch id

One of the main situations in every day life that you may need to unlock your phone and find that the fingerprint reader isn’t working is when your hands are wet—especially if they’re starting to wrinkle up.

To fix this, add your fingerprint fresh out of the shower. This “new” fingerprint will allow for easy unlocking regardless of your hand situation—out of the pool, out of the shower, caught in the rain, or simply just sweating a lot won’t be an issue after that.

Bonus Tip: Name Your Fingerprints

How to improve fingerprint recognition with touch id

This won’t make the fingerprint reader more accurate, but it’s still a good thing to do. Both iOS and Android let you give your fingerprints specific names, which is better than fingerprint 1, 2, etc.

When you name them, you can easily tell what is what. That way, if you ever forget whether you’ve registered a particular finger, you’ll be able to tell pretty quickly. And if you have the fingerprints of multiple people registered, it makes them much easier to tell apart.

Register Your Toes for Quick Unlocking with Your Feet

Just kidding. I don’t even know if that would work. [Editor’s Note: Yes, yes it does. I can now unlock my iPhone with my big toe—in case I’m ever tied to a chair barefoot, I guess.]

How to improve fingerprint recognition with touch id

Apple’s Touch ID is good. The ability to unlock your iPhone or iPad with your fingerprint is a a killer feature that doesn’t work as well on other devices. That said, it can always be better and improved very easily.

We have covered Touch ID before, showing you how to enroll other fingerprints beyond you primary finger. That said, you can improve Touch ID’s fingerprint recognition a great deal by enrolling the same finger two or three more times. Today we want to walk you through this procedure and show you exactly what we mean by this.

Touch ID works surprisingly well but it’s not perfect. Sometimes it just won’t pick up your fingerprint the first time, meaning that you have to pick up and reapply your finger to unlock your device. It’s no big deal but it would still be nice if the whole thing worked more flawlessly.

To improve the accuracy of Touch ID, you can enroll the same finger two or three more times as separate fingers. This means that whenever the fingerprint scanner reads your primary finger, it doesn’t see the difference between that and the other ones you have added, so your iPhone or iPad will unlock much more quickly.

First, open the Settings on your iOS device and tap “Touch ID & Passcode”. You’ll be required to enter your Passcode before you can access these settings.

How to improve fingerprint recognition with touch idAnytime you want to access “Touch ID & Passcode” settings, you’ll have to enter your Passcode.

Now, you’ll see the fingerprints you’ve enrolled thus far. You might only have one. In this example we’ve already enrolled five, included our thumb three times.

How to improve fingerprint recognition with touch idWe’ve already enrolled our fingers, but we should rename them so we can tell them apart.

It probably goes without saying, but it’s very helpful to rename your fingerprints so you can tell them apart.

How to improve fingerprint recognition with touch idSimply tap on the finger you want to rename, and give it an appropriate description.

In this case, you see we’ve enrolled our thumb three times and renamed them so we know which one is which. We recommend you train each thumbprint in such a way that you concentrate on different areas.

How to improve fingerprint recognition with touch idThat should be good enough, our thumbprints are enrolled and our iPad will (hopefully) unlock with less resistance.

For example, if you train the meaty part of the thumb for the first thumbprint, you should train the tip and sides of the thumb for the second one, and so on.

You can do this with as many fingers as you want, presumably there being no limit. You could even add your toes if you wanted. Once you’re finished, your iPhone or iPad should unlock a lot more quickly and hopefully without error or delay.

Learn how Touch ID helps protect information on your iPhone, iPad, and MacBook Pro.

Much of our digital lives is stored on our Apple devices, and we recommend that you always use a passcode or password to help protect this important information and your privacy. Using Touch ID on your iPhone, iPad, and MacBook Pro is an easy way to use your fingerprint instead of a password for many common operations. With just a touch of your finger, the sensor quickly reads your fingerprint and automatically unlocks your device. You can use it to authorize purchases from the iTunes Store, App Store, and iBooks Store, as well as with Apple Pay. Developers can also allow you to use Touch ID to sign into their apps.

Advanced technologies

The technology within Touch ID is some of the most advanced hardware and software that we’ve put into any device. The button is made from sapphire crystal—one of the clearest, hardest materials available. This protects the sensor and acts as a lens to precisely focus it on your finger. On iPhone and iPad, a steel ring surrounding the button detects your finger and tells Touch ID to start reading your fingerprint.

The sensor uses advanced capacitive touch to take a high-resolution image from small sections of your fingerprint from the subepidermal layers of your skin. Touch ID then intelligently analyzes this information with a remarkable degree of detail and precision. It categorizes your fingerprint as one of three basic types—arch, loop, or whorl. It also maps out individual details in the ridges that are smaller than the human eye can see, and even inspects minor variations in ridge direction caused by pores and edge structures.

Touch ID can read multiple fingerprints, and it can read fingerprints in 360-degrees of orientation. It then creates a mathematical representation of your fingerprint and compares this to your enrolled fingerprint data to identify a match and unlock your device. It’s only this mathematical representation of your fingerprint that is stored—never images of your finger itself. Touch ID will incrementally update the mathematical representation of enrolled fingerprints over time to improve matching accuracy.

Security safeguards

Every fingerprint is unique, so it’s rare that even a small section of two separate fingerprints are alike enough to register as a match for Touch ID. The probability of this happening is 1 in 50,000 with a single, enrolled finger. And Touch ID allows only five unsuccessful fingerprint match attempts before you must enter your password. By comparison, the odds of guessing a typical 4-digit passcode are 1 in 10,000. Although some codes, like “1234,” might be more easily guessed, there is no such thing as an easily guessable fingerprint pattern.

To start using Touch ID, you must first set up a passcode on your iPhone or iPad (or a password on your Mac). You must enter your passcode or password for additional security validation:

  • after you restart your iPhone, iPad, or Mac;
  • when more than 48 hours have passed from the last time you unlocked your device;
  • to add or delete a fingerprint to use with Touch ID;
  • to change the iPhone or iPad passcode or Mac system password, and for other security settings like FileVault on your Mac;
  • when there have been more than five unrecognized Touch ID authorization attempts in a row; and
  • after you log out of your Mac.

To improve security, you can choose a long, complex alphanumeric password. On your iPhone or iPad, tap ‘Passcode Options’ and select Custom Alphanumeric Code.

If your device is lost or stolen, you can prevent Touch ID from being used to unlock your device with Find My iPhone Lost Mode. Starting with iOS 7, your iPhone and iPad offer additional protection against theft with Activation Lock, which requires an Apple ID and password to turn off Find My iPhone, erase data, or reactivate your device. If your MacBook Pro with Touch ID is lost or stolen, erasing your Mac remotely also disables Touch ID.

You can also use Touch ID to purchase content from the iTunes Store, App Store, and iBooks Store, instead of entering your Apple ID password.

Touch ID can be used by multiple users on a MacBook Pro, making it easy to share a system securely. Each user account can have up to three enrolled fingerprints, and a total of five fingerprints can be enrolled across the system.

Secure Enclave

The chip in your device includes an advanced security architecture called the Secure Enclave, which was developed to protect your passcode and fingerprint data. Touch ID doesn’t store any images of your fingerprint, and instead relies only on a mathematical representation. It isn’t possible for someone to reverse engineer your actual fingerprint image from this stored data.

Your fingerprint data is encrypted, stored on device, and protected with a key available only to the Secure Enclave. Your fingerprint data is used only by the Secure Enclave to verify that your fingerprint matches the enrolled fingerprint data. It can’t be accessed by the OS on your device or by any applications running on it. It’s never stored on Apple servers, it’s never backed up to iCloud or anywhere else, and it can’t be used to match against other fingerprint databases.

Apple released iOS 7.1.1 earlier in the week, which included improvements to Touch ID fingerprint recognition according to the release notes.

Many iPhone 5s users have reported that unlocking the device with Touch ID is “instant” after upgrading to iOS 7.1.1.

So how did Apple manage to achieve this? A reddit user provides some interesting insight into how Apple has improved Touch ID fingerprint recognition in iOS 7.1.1. It is not clear how he has access to the information. He starts off by explaining how Touch ID works:

Touch ID takes a 88×88 500ppi scan of your finger and temporarily sends that data to a secure cache located near the RAM, after the data is vectorized and forwarded to the secure enclave located on the top left of the A7 near the M7 processor it is immediately discarded after processing. The fingerprint scanner uses subdermal ridge flows (inner layer of skin) to prevent loss of accuracy if you were to have micro cuts or debris on your finger.

He then goes on to explain how Apple has improved the system in iOS 7.1.1:

With iOS 7.1.1 Apple now takes multiple scans of each position you place finger at setup instead of a single one and uses algorithms to predict potential errors that could arise in the future. Touch ID was supposed to gradually improve accuracy with every scan but the problem was if you didn’t scan well on setup it would ruin your experience until you re-setup your finger. iOS 7.1.1 not only removes that problem and increases accuracy but also greatly reduces the calculations your iPhone 5S had to make while unlocking the device which means you should get a much faster unlock time.

If you haven’t noticed an improvement with Touch ID after upgrading to iOS 7.1.1 then you should try to delete the finger from the Settings app (Settings > General > Touch ID & Passcode) and set it up again.

Touch ID is easily one of my favorite features of iPhone 5s, and it is great to see Apple continuing to improve it.

Let me know what has been your experience with Touch ID after upgrading to iOS 7.1.1.

How to improve fingerprint recognition with touch id

Touch ID might come back on new iPhones.

The iPhone X boldly killed Touch ID and replaced it with Face ID, but fear not: Apple might bring the beloved fingerprint sensor back. Eventually.

One of the most well-sourced Apple analysts, TF Securities’ Ming-Chi Kuo, says in his latest investor’s note (via 9to5Mac) that Apple will reportedly release iPhones with a new in-display version of Touch ID in 2021.

The 2021 iPhones won’t drop Face ID for the new in-screen fingerprint sensor, though — they’ll coexist on the same device.

Prior to the release of the iPhone X, Apple was rumored to be working on an in-display fingerprint reader for iPhones, but scrapped it due to poor responsiveness and reliability. Considering how crappy many in-display fingerprint sensors on Android phones are, Apple probably made the right call.

Upgrading the sensor game

There are still challenges for Apple to overcome. “Power consumption, size of the sensing area, thickness of the sensing module, and the production yield rate of the lamination process,” are cited by 9to5Mac as hurdles Apple hopes to clear with its new in-display Touch ID solution.

Kuo believes Apple will solve many of these technical challenges within the next 18 months thanks to new innovations and previously unavailable technology. The analyst claims Apple’s Touch ID could be based on Qualcomm’s “3D Sonic Sensor” in-display fingerprint reader the chipmaker introduced with the Snapdragon 855.

As we previously noted, an ultrasonic sensor works differently compared to the optical in-display fingerprint readers found on many Android phones such as the OnePlus 7 Pro. Whereas an optical sensor illuminates your fingerprint from underneath the screen and matches it with fingerprint images stored on the device, an ultrasonic sensor uses high frequency sound waves to trace your fingerprint’s grooves and identify it.

Ultrasonic sensors come with the advantage of being more accurate, reliable, and secure. They’re also thinner than optical sensors and would be a better fit for the slim design tolerances Apple demands.

Another big change

If Kuo’s reading of the tea leaves is correct, it’d mean Apple walking back on the brief era of iPhones — iPhone X, XS, XR, and whatever new iPhones come in 2019 and 2020 — that only have Face ID.

While Touch ID’s return will likely make many iPhone owners happy — lots of people don’t like Face ID because it’s slower and not as responsive as a fingerprint scan — Apple would likely spin the feature as another layer of security for your iPhone data.

One biometric sensor is good, but two? That’s like having two-factor authentication turned on. And with Apple’s hard-line stance on privacy, you can bet good money it’s going to flaunt a Touch ID that’s complementary to Face ID as a major advantage over Android phones.

An in-display Touch ID could also make iPhones more competitive with Android phones, which all seem to have in-display fingerprint readers nowadays. Who knows, maybe Touch ID is enough to improve stagnant iPhones sales.

Of course, despite Kuo’s impressive track record, we’re talking about iPhone features that are two years out. And even though companies tend to lock in design and features at least a year before manufacturing begins, there’s still plenty of time for things to change.

Still, Touch ID returning to the iPhone? You gotta wonder if outgoing Chief Design Officer Jony Ive is rolling his eyes like a mad man.

All future matching will happen against enrolled fingerprints. Hence it is very important that the enrollment template is of high quality. Many biometric projects fail because users are not being identified correctly during daily use.

Here are many simple steps that you can take to guard against this:

1. Use the best available fingerprint reader

Selecting the right fingerprint reader is a very important step.

If the biometric scanner that you are using for registration cannot take the best images then the whole system will fail as you will end up registering bad quality fingerprints. Your biometric database will contain substandard fingerprints. Selecting the best fingerprint reader is discussed in my previous blog post.

I can understand that best fingerprint scanners are expensive and might not always fall in budget. If that is the case then you can use high end fingerprint scanners for registration and low end fingerprint scanners for matching.

2. Train users to place the finger correctly on the fingerprint scanner

To get the best fingerprint images, the finger should be placed directly on the finger scanning area of the fingerprint sensor. Usually the tip of the finger is at the top of the finger sensing area and the finger is centered from left to right.

According to HID:

For the best quality images, fingers should be placed such that a maximum area of the fingerprint is imaged. Generally this means that the first knuckle of the finger is at the bottom of the platen and the fingertip is at the top, with the finger centered on the platen from left to right.

How to improve fingerprint recognition with touch id

3. Capture multiple images of the same finger

During registration of fingerprints, capture multiple images of the same finger to create a consolidated fingerprint template. More fingerprint samples means the fingerprint scanner software or fingerprint algorithm has more minutiae points to create a very good fingerprint template.

Tip: Please ensure that when you are capturing multiple images of the same finger, the user lifts their finger and places it again on the scanner between each capture. The advantage of capturing multiple images of the same finger is eliminated when the finger is not lifted between each capture.

4. Capture only best fingerprints and discard not so good ones

Incorporate fingerprint quality check in your fingerprint capture process. Ensure that you only use the best quality fingerprints to create the fingerprint template. You can discard fingerprint images that are not so good. This might increase your registration time by few seconds but it is definitely worth it and will saves tremendous amount of time to users during day to day use.

Performance of biometric systems is dependent on the quality of the acquired input samples. If quality can be improved, either by sensor design, by user interface design, or by standards compliance, better performance can be realized. For those aspects of quality that cannot be designed-in, an ability to analyze the quality of a live sample is needed. This is useful for the real-time selection of the best sample, and the selective invocation of different processing methods. It is the key component in quality assurance management.

Tip: You can do fingerprint image quality check using NIST Fingerprint Image Quality algorithm (NFIQ).

5. Always capture multiple fingerprints

Capturing multiple fingerprints ensures that there is a backup in case of injury. Also, if user is having trouble being identified via their index finger, they can use alternate finger.

How to improve fingerprint recognition with touch id

6. Use Rolled fingerprints

Rolled fingerprints capture more minutiae and larger fingerprint area ensuring that the template has lots of fingerprint data points. You can consider using rolled fingerprints for registration.

Bonus: 7. Adjust the fingerprint matching threshold based on your application

Every Fingerprint software has a pre-defined fingerprint matching threshold. It is highly unlikely that 2 fingerprint minutiae templates acquired from same finger at different sessions will be 100% exact match. Hence during fingerprint matching, the fingerprint software compares 2 fingerprint templates and returns a match score. If the match score is higher than the predefined match threshold then the input template is said to have successfully matched with the stored template.

If the match threshold is set too high then you will be have high False Rejections. If the match threshold is is too low then we will have high False Acceptance (BTW: we never want this).

It is important to adjust the fingerprint matching Threshold based on your application. For example, Biometric Attendance Software does not require the same threshold as Biometric Banking Software.

According to Webopedia False Acceptance Rate and False Rejection Rate are defined as is

The false acceptance rate, or FAR, is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user.
The false rejection rate, or FRR, is the measure of the likelihood that the biometric security system will incorrectly reject an access attempt by an authorized user.
