Credit Card Number Also known as Primary Account Number PAN. The one thing to point out is that credit card numbers have some unique properties. For instance, the first number of the card number will vary depending on the type of card. Card. Starting Number. Visa. 4Master. Card. Discover. 6. A great article about credit card numbers is Anatomy of Credit Card Numbers. Another notable thing about the card number is it is actually created using a particular algorithm and thus there is a check, called the Luhn 1.

Card, Visa, and Discover cards have it printed on the back, usually in the signature box. Mag. Stripe Data. The magnetic stripe on the back of the card is broken up horizontally into three tracks, the tracks often contain duplicate data and most times track 3 doesnt really contain any data. ISOIEC 7. 81. 3 Defines the attributes of this data, and these sites describe the data available on each track in detail To read the data, youll need a magstripe reader that will support reading all three tracks. Most magstripe readers emulate a HID human input device, so its surprisingly easy to read from them just open a text capturing program and swipe a card. The reader Im using is the Mag. Tek Sure. Swipe 2. So lets see what data well get from the magstripe B5. XXXXXXXXXXXXXX2ANTONIEWICZBRAD1. XXXXXXXXXXXXXX21. Lets break down this data Track 1 Data. Track Data. ValueStart. BFormat Code BBank5.

But where the heck is that Track 3 dataWell. RFID Interface EMV Chip. In the last couple of years, the RFID Interface has been most talked about. Something about the idea of an attacker reading your credit card out of your pocket, seems to bother people The RFID Interface specifications were designed by a group of representatives from Europay, Master. Card, and Visa EMV and is thus often referenced as the EMV Chip or just EMV. The three things that differentiate this interface from the others are Card Holder Name On most cards the cardholder name is not stored within the chip, instead its replaced by something like VALUED CUSTOMER or NOT SUPPLIEDService Code The service code that permits where the card is used and for what changes on the contactless interface. CVV or Dynamic CVV Rather then using the same CVV that is stored on the Mag. Stripe, the smartcard capabilities allows for extended functionality, and so the designers created something called a Dynamic CVV. This CVV changes which each read of the card. The RFID Interface is defined mostly in ISOIEC 7. EMV Specifications. Vivo.
