OSDP™ and Access Control: Why the Wiegand standard is changing and how to manage the transition

If you've ever been skiing, you can appreciate being able to pull on a pair of ski boots, step into the bindings, click the bindings into the skis, and not think twice about whether the boots or bindings were made by the same manufacturer as the skis. That's because ski equipment manufacturers use the same industry standard. Very soon, security access control practitioners can count on the same level of consistency, thanks to the Open Supervised Device Protocol (OSDP™) standard adopted by the Security Industry Association (SIA). The protocol specifically applies to peripheral devices (PDs) such as card readers and other devices at secured access doors/gates and their control panels (CPs). OSDP both standardizes the reader-panel connection and secures it.
