Keysy Rewritable RFID Key Fobs (5-Pack, Black/No Logo)

These Keysy rewritable RFID key fobs (Black/No logo) work with the Keysy RFID Duplicator (sold separately) to make one-to-one copies of your original 125kHz RFID key cards/key fobs. What is 125kHz RFID? 125kHz RFID refers to keycards/keyfobs that need to be held less than 10cm from the RFID reader. Typically found in HOA communities, office buildings, swimming pools, schools, gyms and elevators of condos, parking garages, and apartment complexes. “RFID” stands for “Radio-Frequency Identification”, which is a fancy term for the process by which electronic key fobs are able to lock and unlock doors.
