Does CVV track data?

**The CVV (Card Verification Value) is a cryptographic signature of the card number, the expiration date and the service code to verify the integrity of these data in the track. It is calculated with an algorithm similar to that of PIN encryption.

How do I read magstripe data?

A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head.

What is the difference between CVC1 and CVC2?

While CVC1 is encoded in the magnetic stripe, CVC2 is only printed on the card itselfthree-digits on the back under the magnetic stripe for Visa, Mastercard and Discover, and four-digits on the front for American Express. It is only intended for authenticating the card owner during the purchase.25 Aug 2012

What does track 2 data contain?

Track 2. This format was developed by the banking industry (ABA). This track is written with a 5-bit scheme (4 data bits + 1 parity), which allows for sixteen possible characters, which are the numbers 0-9, plus the six characters : ; < = > ? .
