Hello,
Nowaday, we are going to design an IC chip for magnetic-stripe card reader(e.g credit card reader). So I must understand the any aspect of the megnetic-stripe card, but the data for it is quite less. At present, I only know the basic structure of magnetic-stripe card with 3-track which used for credit card and the data of it is storaged as "0" "1". But I don't know how the megnetic card to express "0", "1". In some data, it is said that "0" "1" is expressed through the difference polarity of the megnetic. Is that right and what is the difference to the signal (e.g current and voltage signal) of the megnetic header when to read the "0" "1" data?
Can any body help me, please?
Thank you!
Best regards
