Acquisition principles
Areas of interest
As regards fingerprint, the area containing the most relevant biometric data is usually
located in the centre of the first phalanx.
As regards blood vessel pattern, the area of interest is usually located between the first
and the third phalanxes.

Ergonomics
Image acquisition is performed with CMOS camera. The optical imaging method
depends on the kind of biometric data to be acquired. The fingerprint imaging process
requires finger's first phalanx (fingerprint area) to be in contact with the corresponding
sensing area (square portion of the transparent surface). A finger tip guide (1) has been
designed to help user to place the first phalanx of the chosen finger in the centre of the
fingerprint imaging area (2).
