Magnetic stripe examples: standard cards


L. Padilla

This page shows the contents (and its possible meaning) of some standard magnetic stripe cards, see track formats for additional details. Part of the information has been changed for obvious reasons. By now you can find:


*** means digits which change randomly from card to card.
XXX means digits which appear repeatedly in the same card.
