MDB protocol in use for cash machines

[Igor]

Did someone work with this kind of protocol ?
I need to develop software communication between vending machine and my
PCB, based on Atmel MCU.

From card reader i have to read out data like transaction, money status
etc. data like card ID and money status are standard.

I saw some examples on the net but it's not much.
Any link or code is welcome

btw. im using ASM and C.
