READMAGCARD problem

Hello,

I'm connecting a card reader to an ATMEGA64, and I'm trying to use the function READMAGCARD. The problem is that when I call that, the program stops running, and it won't go further unless I swipe a card in the reader... is there a way to stop that particular function, or a way to detect if a card is being swiped?

Thanks in advance,

Call the READMAGCARD function only after the CS line goes low, that is call the function only if the reader sense any card.

Thank you binu_ji, for your help. I had allready done that, but that only solve half the problem, because if a card is "badly swiped", the program will stop anyway until another card is swiped.

Did you get the data for both direction.
I am getting 37bytes for track 2 at one direction and when i swipe the card on the other direction i am getting only 1 byte.
Anybody get this problem.

I have solved it now with 8051 Microcontroller with my own code to read the magnetic stripe card on both directions.
