MDB protocol in use for cash machines

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.
