This document describes the specifications of Atmel's AT77SM0101BCB02VKE FingerChip biometric module. Based on Atmel's FingerChip fingerprint sensor, ARM9 microcontroller and flash memory, the AT77SM0101BCB02VKE provides the main biometric functions such as user enrollment, authentication and identification in a packaged module, making it easy to integrate into a final system.

The AT77SM0101BCB02VKE is particularly well-suited to Physical Access Control, Point of Sale devices, Time and Attendance or Vending Machines.

The AT77SM0101BCB02VKE provides great flexibility because of its memory capacity and powerful microcontroller loaded with the Linux operating system, and features many possible interfaces, including Ethernet. The AT77SM0101BCB02VKE biometric module requires the purchase of the Evaluation/Development Kit AT77SM0101BCB02VEK to develop the user interface of the final application.

Functional Description

The AT77SM0101BCB02VKE is a biometric sub-system based on Atmel’s FingerChip fingerprint sensor. It comprises a fingerprint sensor connected to a board that embeds processing capabilities through an ARM9-based AT91RM9200 microprocessor, and memory to store the software and fingerprint templates.

The biometric module must be connected to a motherboard for power supplies and interface connections. Connection to the motherboard is achieved through two standard connectors located on the sides of the module board.

The module is loaded with a Linux operating system, an Atmel driver for the FingerChip sensor, and by default, authentication software biometric library for extraction of fingerprint characteristics and comparison with enrolled templates also called bio-engine . The standalone module can perform the following:
• Enrollment an operation where the end-user scans his fingerprint by sweeping it across the FingerChip sensor, providing a fingerprint signature reference template
• Authentication accurate matching of the newly acquired fingerprint against the template stored in the board’s memory during the enrollment procedure, used to validate user authentication
• Identification matching of the fingerprint image against the correct template within a database of previously acquired templates

These three functions can then be used in any application requiring authentication to grant rights to a user, or to change criteria of the user’s profile. Examples of typical applications might include physical access control or time and attendance monitoring.

The AT77SM0101BCB02VEK Evaluation Kit provides all the tools necessary for easy development of a customized application using the biometric module APIs.

The AT77SM0101BCB02VKE biometric module lets you add convenient and secured user authentication to your products in a surprisingly reduced development time.
