What card reader do you have? Some card readers that use the microphone jack like Square's has an encryption chip. You have to modify the reader to use it without their software.

The reader is simple Chinese reader with no encryption
I just need the library or sample for reading the magnetic card with it
Once i solve this all is done.
I know it is being used with iphone and android.
Thanks
