These Permanent Locking Proximity Card Holders - 50pk are ideal for organizations that use proximity cards for door locks but want to give their employees the option of using a lanyard or badge reel. These holders allow you to slide the prox card into the holder and then permanently lock it in place. The card can't be removed but it can still be read by your proximity sensors. The holder includes a slot and chain holes for use with common lanyards, badge reels and neck chains. Plus, you can even use these holders to carry 2 cards (just remember that once they are locked it is permanent).
