Here's how Touch ID was made faster and more accurate in iOS 7.1.1

Touch ID on iPhone 5s

We now have a better idea about what has been causing Touch ID accuracy issues for some users, as well as what improvements were made to the system in last week's iOS 7.1.1 update. Many Touch ID errors appear to stem from bad setup scans, which prevented Touch ID from improving over time for several users. It appears that iOS 7.1.1 solves this issue, as well as reducing the number of calculations the iPhone has to make, speeding up the unlocking process, according to Reddit user iOSecure:

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.

Is Touch ID working better for you since you updated to iOS 7.1.1? Let us know below in the comments.

Here's how Touch ID was made faster and more accurate in iOS 7.1.1

I had about 95% success before the update after I followed some advice I found that basically "over trained" the scans. I did notice after the update the phone send to be unlocking much faster. Only issue I have with touch ID now is after I take a shower it doesn't seem to register for a few minutes. I'm guessing that has to do with some wrinkling of the skin on the fingers from the hot water from the shower.
I wish they would implement more uses for touch ID because I really love it.

You can solve this problem by registering you finger after you shower, in addition to the prints you've already done.

I'm on the other camp... I feel it's way slower and unresponsive... Maybe I need to re-scan my fingerprints under 7.1.1?

Worked great, now started having problems. Would not work at all. Reboot, delete, and reset prints. I get a try again often, and it's off and on. I cleaned the screen area, and still off, and on. Kind of strange. Once, and only once I entered my pass code, and counted a full three seconds before the screen opened. That was strange also.

Sounds like you have something else going on, perhaps you need to do a fresh install. Use your computer & iTunes, Backup to iTunes, Restore as new, then restore from backup. Good luck!

I just picked up a 5S last week to replace my 4S and Touch ID works great so far. I was holding out for a new 6, but an unfortunate accudent involving my 4S and a lawn mower resulted in a new phone for me. Even with the top 25% of the screen gone and the metal band severely deformed at the top, the 4S would still make phone calls via Siri.

Seems slower for me. It recognizes my prints 99% of the time but it just seems slower now to unlock my phone. It was fastest under 7.0!

I had reliability problems under 7.0. It would work great for a while, and then it would start failing about 1/3 of the time which was very annoying. Re-registering my fingers would solve the problem for a while.

Since 7.1, it just started working magically for me. It literally works 100% of the time now unless when my finger is wet or dirty, and it is very fast. I LOVE IT!!!

It actually started working so well, I though it might be broken. However, it always rejects my unregistered fingers, or my daughters' fingers, so it is working.

Touch ID was terrible for me from the start. But with this last update, I have fewer failures and my phone unlocks quite fast.

We never had any issues, with three 5S phones in the family.

But 7.1.1 is faster with touch-ID, it unlocks instantly every time - with any of the fingers I have programmed.

Moisture seems to cause delays though, if it's rainy and my finger is wet it takes longer to recognize.

Now a good friend has had nothing but issues with 7.0 - his fingerprints never last more than a week before they stop working. I have seen it in person many times. The worst part is his company controls updates (it's a company phone) and won't let them go to 7.1 or 7.1.1 yet...

Thats dumb they wont let him update from 7.0. Especially with the SSL bug that was patched in 7.0.6.

Its probably because his company doesn't want to pay the update support costs for 7.1.1 which is really stupid. That upgrade fixes a lot of annoying probs from 7.0

Works fast at first, then starts getting slower to unlock the phone. Don't know what's happening.
