Proximity Cards

Prox Cards

Proximity — or Prox— cards utilize 125 kHz radio frequency in the form of contactless cards, fobs, and tags. When held near an electronic reader device, proximity cards enable the identification of an encoded number and allow door entry.

Proximity cards are available in multiple formats, including clamshell, printable PVC, retransfer-ready composite, fobs, and tags. Find what you need from 3iD below, and be sure to contact us if you need assistance!
