A SABRE is a small reader, designed by Safetrust, that allows mobile devices to communicate over BLE (Bluetooth Low Energy) to RFID readers, computers, or other devices that require a relay output, such as a security gate controller. SABRE’s act as gateways by translating secure data that is sent from the Safetrust Wallet, or other supported mobile applications, into a format that can be read and understood by the destination host system.
