имеется Arduino Leonardo и rfid reader RDM 6300

Прочитал все темы у нас, остановился на этой

Ридеры похожи, но не тоже самое. тем не менее по указаниям запустился скетч, но на любую карту выдает следующее 

/* Modified from
* Crazy People
* By Mike Cook April 2009
* An RFID reader outputing 26 bit Wiegand code to pins:-
* Reader attached to Pins 2 & 3
* Interrupt service routine gathers Wiegand pulses (zero or one) until 26 have been received
* Then a string is sent to Serial
