 * Usage and assumptions:
 * a RFID reader Model MF7(1.05) is configured in wiegand mode and attached 
 * ports per call to class (could be to p5 & p6 via a level converter as to
 * isolate the 5V source voltage from the 3.3V needed by MCU, this can easily
 * be done with diode in series with signal data0 and data1 of RFID reader and
 * pull up on MCU side.
