Biometrics continue to be an important security solution, with fingerprint
recognition among the most common implementations (see "Biometrics Wields
A Double-Edged Sword" at www.electronicdesign. com, ED Online 10605).
Atmel and ODI Security have combined forces to design a module that simplifies
system integration.
The Fingerprint Matching Module uses Atmel's FingerChip sensor and a specialized
ARM7 microcontroller (see the figure). It
has a serial and infrared interface, and it can store fingerprint information
for up to 20 users. The IR support can be used in a multilock application to
maintain the user template database of locks using a secure PDA or laptop. All
modules contain LED feedback plus low-battery indication and can drive up to
five different lock actuators.
Atmel's software development kit costs $995. It includes a module and software
that supports external databases.
