What is this Encoder for? What's the difference between Encoder and Reader or Writer? There is a device named Encoder in the list of devices for Mag-Stripe card. Is there any difference between Mag-Stripe card reader and writer? Or like smart cards reader, the reader do the writing also?ĭoes all the readers can read from all the three tracks by default and we choose that which track is our target on the program? or some readers are for Track-1, some other for Track-2 and some other for Track-3? In the other word, does the device need three different head(Is it a head?) for working with different Tracks or a single head are for all the three Tracks?Īre these three Tracks both readable and writable or some are only readable for example?ĭoes we need fresh cards to writing data on them or we can clear an already used card and rewrite new data on its Tracks? And the density of data on each Track is different from the others. This cards have 3 different Tracks named Track-1, Track-2 and Track-3 in their black bar. Searching a lot, gave me this information only : But if I don't have any idea about the structure of these kind of cards, I can't develop software for them also. I am newbie in the field of Magnetic-Stripe cards.
