GateKeeper Token vs. RFID Cards.
GateKeeper® hardware token key fobs have several advantages above RFID cards.
RFID cards require scanning and is cost-prohibitive.
How are employees at home or traveling going to login? Are they going to carry an RFID scanner with their laptop everywhere they go? Although RFID cards are cheap to replace, the readers are expensive to maintain and upgrade.
Proximity authentication happens automatically over the air, so there's nothing to scan. GateKeeper also continues to authenticate even after logging in, making the system more secure without relying on human trust. No need to pull out a card every time you log in. Log in and out faster than ever. No tag collisions.
