how to make a magnetic card reader and writer

When i open the demo application under the magnetic stripe tab they are two columns

What i need mainly from this device is Magnetic Stripe Write, i need to write data to a blank HiCo magnetic card. For example, if you swipe your credit card or driver's license, it will recognize it, and show you all of your personal information that is stored on that card! Although, since this setup outputs data directly to the serial port of the computer, I'm sure that with a little code hacking it wouldn't be too hard to get this reader to interface directly to Stripe Snoop.I have recently bought a Magnetic Reader/Writer from China ( YL160 4 in 1 Reader/Writer)Īnd it came with the Demo application along with the API. This software requires a slightly more complicated hardware setup, but comes with a database of known card formats and will attempt to parse human-readable data out of any card that you swipe through it. It also contains information about the standard formatting of the tracks on magnetic stripes, which is helpful in interpreting data that you get from the setup shown in this instructable. This document is pretty much the bible on the nuts and bolts (volts?) of how magnetic stripes physically work.
