The Compact Reader 3078 brings passive smartcard technology to any SimonsVoss lock. When mounted near the SimonsVoss lock, this wireless reader allows MIFARE Classic or MIFARE DESFire cards to be securely used as access credentials. All communications are encrypted and protected against “replay” attacks. It also supports SimonsVoss’ new G2 protocol which expands the number of possible users to 64,000 per lock and enables a full-featured virtual network where the credentials are used to convey information to and from off-line locks. The virtual network dramatically reduces the infrastructure costs of communicating with the locks while still making it possible to communicate with each lock from a central location.This reader works with any SimonsVoss lock present or past.
