It’s hard to believe that the physical industry continued deploying readers with antiquated insecure Wiegand protocol. The rest of the world has incorporated seamless secure communications on just about every piece of hardware sold.

OSDP is huge step forward in allowing readers and other security devices to become intelligent and have the ability to fully communicate with the rest of the world.
