  Agreed. I found this bit about Touch ID interesting: > With one finger enrolled, the chance of a random match with someone else is 1 in 50,000. However, Touch ID allows only five unsuccessful fingerprint match attempts [...] I assumed it was more accurate than 1 in 50,000. Then again I don't know what a normal fingerprint sensor is capable of. Does anyone know the accurate of the sensor in the new S5, or the sensors that IBM/Lenovo/etc. have put on laptops? Also: > The 88-by-88-pixel, 500-ppi raster scan is temporarily stored in encrypted memory within the Secure Enclave while being vectorized for analysis, and then it’s discarded after. I wonder what kind of neat stuff people could come up with if we had raw access to that kind of sensor data.

    As I understand it, most fingerprint scanners can only distinguish between on the order of tens of thousands of fingerprints. 50,000 is higher than other numbers I've heard for fingerprint scanners (30-40k).
