Hi to all,

I am planning to work on iso7811 2 track card reader.
According to data sheet each track has clock, data and card in pins
And all 2 tracks are going to output data and clock at the same time.
The data is valid when the clock is low and the data
After reading must be inverted. I use 18f242 My question is
If I connect 2 clock outputs to INT0 and INT1 and setup
Interrupt to foiling edge should I be able to read it right?
Do I ever need to use interrupt for this. Any help will
Highly appreciated.

Andre
