First post here, but what do people think; is the cut away I've highlighted in my image a position for the authentec AES2750?(http://www.authentec.com/a/Production/smartsensors_mobile/AES2750.aspx), Remember Apple now owns Authentec, the company which manufactures the AES2750.
Here's Authentec's brief description of the AES2750:
It looks to me like the cut away I've highlighted has a protective film covering the glass beneath, if the film is removed, the sensor can operate through the glass.

Here's Authentec's brief description of the AES2750:
Worlds first fingerprint sensor designed specifically for mobile wallets; combines strong fingerprint security and encryption in a narrow and durable package.
AuthenTecs new made for mobile commerce smart sensor, the AES2750, adds strong but effortless security todays NFC mobile wallets. It incorporates the best features of previous AuthenTec smart sensor designs, including a wide 192 pixel by 8 pixel fingerprint sensor array, with many new features including hybrid fingerprint matching (on sensor match + host match) and encryption in a narrow package for easy and inexpensive integration. http://www.authentec.com/a/Production/smartsensors_mobile/AES2750.aspx
