RFID Wiegand Output

Hi John

Thanks for your reply. I have tried using a few different tags and getting some odd results. They seem to vary in length. I would assume for each tag I should get 26 binary digits? I was hoping that from here I can parse out the tag ID. It seems to vary depending on the batch/ type of tag I use. Is this normal or is there something I'm doing wrong in the code?

Cheers

Jason
