From what I’ve read about the Touch ID, it seems that Apple has the competitive edge with its new fingerprint sensor.  In fact, it can identify your finger when the phone is in any position.

In a recent article, which included a review of the new hardware, some of the key attractions of the Touch ID fingerprint sensor are:

• The sensor is built into the Home button; however, in addition, you must setup a passcode as a backup. If a finger match fails three times, the phone offers an opportunity to use your passcode.  If the finger ID fails 5 times the passcode “must” be used.
• Did you know you can use more than one finger? ! Yes, you can!  A brief training session for each finger is required.
• Apple says the odds are 1 in 50,000 that another person’s finger would work.

One bug that needs to be addressed:  the phone does ask for a password when trying to use the finger to authenticate an online purchase. You can read the article details by clicking this link via iPhone 5S Review: New Touch ID for iPhone – WSJ.com.
