Credit card reader from headset jack

Hi!
I have bought a credit card reader for my nexus one. This is a device that plugs into headset jack and you swipe the credit card for this or any card with magnetic striper.
I wanna know if there is a way to read the information it sent by headset jack?

This is some new for me but I need this device to read identification ID.

Any ideas?

I suspect this of being an Android device. In which case, better to ask in the separate Basic4Android forum.
