Turn your Arduino into a Magnetic Card Reader!

Step 9 Code Download and Wrapup

In this instructable I've discussed some basics of magnetic card readers and shown you some code to get you started in the right direction in reading data from magnetic cards. There's plenty more work that could be done, such as reading and decoding the 2nd track, calculating the LRC and calculating the odd parity on each byte.

The full source code is available for download below. It was written in AVR Studio 4.17.

I hope you enjoyed this instructable and, as always, I look forward to any comments or suggestions that you may have.

Happy coding and AVR'ing!

Awesome work on this. You explained all the steps in a way that takes something that is compli cated and kept it interresting all the way through. I didn't know much about what was on a stripe and now I have at least a basic idea . Thanks for the education!
