Apple’s latest toy – the iPhone 5S – comes with Touch ID, a fingerprint scanner that scans your finger and then unlocks the phone. While this feature usually works great, some users have complained that sometimes the iPhone won’t read the fingerprint and prompts them to “try again.” Often placing the finger on the Home button would prompt this error (even though you’re doing it right) and the user needs to place the finger again. This is a nagging issue for some users.
So what to do in such cases? Apple Inc. (NASDAQ:AAPL) recommends that users rescan the finger, but before that ensure that your finger is clean and dry. If you’re having trouble scanning one finger, try a different finger. Apple clearly notes that things like sweat, moisture, oils, cuts, lotions and dry skin affect Touch ID’s capability to recognize your fingerprint.

Multiple scans of same finger can boost recognition
The outcome of enrolling only one finger multiple times is that your iPhone will better recognize your finger. This tip will greatly improve your iPhone’s fingerprint recognition technique thereby reducing that nagging “Try again” error.
