*The Open Supervised Device Protocol (OSDP) is a global standard approved by the Security Industry Association (SIA) and International Electotechnical Commission (IEC).
OSDP is an access control communications protocol nurtured by a SIA consortium, consisting of some of the smartest individuals from the security industry. Version 2.2 of the SIA OSDP is its most recently updated standard that improves interoperability among access control and security products such as readers and controllers. The standard also applies to peripheral devices such as card readers and other devices at secured access doors/gates and their control panels.
