ProxsafePROXSAFE is a modular system for safekeeping and management of keys and valuables and is uniquely the only RFID-Based Key Management System in the world. Each key is securely attached to an electronic RFID key Tag. The key is locked in the proxCylinder where its code is read and monitored contactlessly. The system is operated via a proxSafe user terminal. The terminal identifies the user and verifies his key assignments.
