How many times a day do you enter the code to open your iOS device? I haven’t kept records but I estimate at least 25 times a day I have to enter my six-digit code. The new Touch ID on the iPhone 5S will make life so much easier. The new A7 chip might be five times faster than the A6 in the iPhone 5, but this improvement to user authentication will save us even more time. It is one of the most exciting features of the new iPhone 5S.
