Good day. I have recently become very interested in magnetic stripes; how they store data, how the data is read etc. They are something we use every day in our lives but what few people fully understand, and as a result, there is little documentation avaiable (from what I can find) that goes in debth about them. I want to learn everything I can about them, which is why I am posting here; to ask if anybody knows of some good documentation about magnetic stripe cards and readers? Thanks.
