Magnetic stripe reader/writer

This page contains information about some simple designs I made to read and to write magnetic stripes. By now you can find:

The circuit description of the old reader.
The circuit in Micro-cap III format.
The program to use the circuit. Compiles with Turbo C++ v1.01, download it for free!
I found this batch file very useful.
Simpler and more reliable reader for computers with sound card. No electronics needed!
Ptit-Kaneda's Windows version of my linux program, including a very nice graphic enhancement and ideas for the mechanics of the reader.
Turn your mobile into a portable magnetic stripe reader! (aka skimmer).
A very simple writer for computers with serial port. No electronics needed! New!
Some examples of the contents of standard magnetic stripe cards.
Some examples of the contents of non standard magnetic stripe cards.

If you try any of these designs let me know how do you progress with it!
