Prox Fob

ZK’s Industry standard 125 KHz generic prox cards can be used with any of ZK readers which contain an internal prox card reader.

When ordering ZK readers, be sure to specify which card reader technology and cards you need PRIOR to placing your order.




  • Since customers sometimes are already using existing non-ZK card readers and cards, ZK also provides 125 KHz key fobs which can be clipped on to cards having a badge clip slot
  • For customers having non-ZK cards with no badge clip slot, we also offer 125 KHz self-adhesive RFID discs which can be easily adhered
