Module Puts Its Finger On The Pulse Of Security

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.
