Suprema, a pioneer in access control, biometrics and time & attendance solutions, announces that its compact outdoor RFID reader, XPass D2 has been verified by SIA as OSDP compliant.
OSDP, or Open Supervised Device Protocol, is an open-source protocol devised to improve interoperability among access control products from different manufacturers. OSDP enables bi-directional communication between readers and controllers, an improvement from one-way data transmission of Wiegand interface.
