how to interface fingerprint to pic microcontroller
Abstract
As each day brings increasing opportunities for fraud and greater needs for security, biometric fingerprint sensors represent an attractive and convenient authentication method. In today’s networked world, there is no doubt that ngerprint biometrics will become an increasing part of everyday life, including personal authentication solutions.
Remarkable innovations in recent years have reduced the size, lowered the price, and improved sensor performance. These developments are making it possible to deploy fingerprint authentication beyond law enforcement to more
widespread personal authentication applications. The Biometric Interface PICtail™ Board (Part # TSTEP001), developed by Electronicsteps—a trusted third party tool provider—is available today to assist you with your ngerprint authentication design. It can be attached to the Explorer 16 Development Board and it incorporates a ngerprint reader that uses a recognition algorithm that won an award in the worldwide Fingerprint Veri cation Competition (FVC).
Hardware Overview The Biometric Interface PICtail Board is a complete fingerprint interface solution combining a
ngerprint reader module and a capacitive touch sensor in the same board, making it easy to add fingerprint authentication to new designs. The reader hardware contains a high powered DSP processor that does all the image processing tasks and searching of ngerprint templates algorithms, leaving the Explorer 16 board’s microcontroller free
for user application code.
