Hi Brian,
Thanks for your reply.
My Access control system is very simple (Local brand) which i guess doesn't have special functionality except normal wiegand interface with CARD and pin data verification.
In reader manual, it mention about "card+pin" function mode over wiegand. So, reader itself collect CARD and PIN inputs and then sends to controller over wiegand.
Do we still need controller to be support something specifically for this mode (card+pin) ?
The reader manual at below link:

what is industry standard practice for AC systems (i..e reader and access system) for CARD+PIN mode function between wiegand based reader and Access system ? Any standard communication method avaialble for interoperability between any two ?
