What Biometrics Information is stored on the server?
a great bit long random string, which is unique to each fingerprint. It is a map of 25 to 40 unique features of your fingerprint
and then puts it into a data format called a template.
This data is called Finger Minutiea Data, or FMD. That specific template can only be interpreted by the biometric engine on the kiosk. If one were to look at the template of a fingerprint, it would not be recognizable, as the information is a set of numbers and typically encrypted.
