1 The total system reaction time would including the image capture and readout time as well as fingerprint identification. Therefore this
time depends mainly on the processor performance, the algorithms used for identification and the image capture speed. With the
Infineon FingerTIP SDK running on an 400MHz PC this time is usually less than 500ms.
2 This value is guaranteed only for the FingerTIP module if the notes of the Design-In Guideline are observed.
