OSDP (Open Supervised Device Protocol) improves on the Wiegand protocol primarily by providing which capability?

OSDP (Open Supervised Device Protocol)

Multiple choice — select the best answer

AHigher read range for credentials
BBidirectional encrypted communication between reader and controller
CSupport for 125 kHz proximity cards only
DStandalone operation without a control panel

✓ Correct answer: B. Bidirectional encrypted communication between reader and controller OSDP enables bidirectional, encrypted (AES-128) communication between reader and controller, enabling mutual authentication and resistance to eavesdropping and replay attacks, which Wiegand's one-way unencrypted signal cannot provide.
