The typical magnetic stripe card accommodates three tracks or areas for storing data. Banking and credit card operations rely on this technology, most frequently using Track 2 (sometimes referred to ABA-2 or ISO-2) to store their data. The card must be swiped or inserted into the reader so that the read head can pick up the card’s encoded data. This contact operation creates wear on both the card and the read head. With new high-density magnetic stripes, however, loss of data due to reasons other than physical damage is now uncommon. This technology provides a medium level of security because it is possible, with the right equipment and proper knowledge, to duplicate cards. Yet, lower cost for both readers and cards makes it an attractive choice for many users.
