As a side project for fun, I was going to see if I could replicate my university’s RFID ID card. However, I am new to the field of RFID, and am overwhelmed by the vastness of different protocols.
I tried reading the card with a 125Khz reader with no luck, but my phone (with a NFC reader app), can pick up the card. This leads me to believe that the card operates at 13.56Mhz. Would that be a correct assumption, since NFC operates at that same frequency?
Would any 13.56Mhz reader work, or will I need a specific type? From what I’ve researched so far, there are two popular types for cards, MIFARE and iClass.
Wondering if I could get some guidance in the right direction in what type of reader would be right.
