+ZFM20 FINGERPRINT MODULE
+
+This is a UART-based driver for ZFM20 family of fingerprint modules for AVR
+microcontrollers. I wrote this for and tested with ATmega328P. It should work
+with other AVR microcontrollers as well.
+
+Since ATmega328P has only one hardware UART, I'm using lynxzp's software UART
+implementation [1] for debugging purposes.
