Which of the following is included in Track 1 of card data?

The correct answer identifies that Track 1 of card data includes the cardholder's name. Track 1 contains data encoded in the magnetic stripe of a payment card, which is used primarily in magnetic stripe card readers during transactions. This track holds detailed information that includes the cardholder’s name, account number, and the expiration date, among other details.

Track 1 is typically formatted in a way that allows transaction terminals to read and utilize this information efficiently. The inclusion of the cardholder’s name is important for identifying the individual associated with the card, supporting both transaction authenticity and cardholder verification processes.

The other components provided in the choices have their own specific formats and locations on the card. The expiration date is part of Track 1 but is not the prime defining characteristic of that track. The security code is not included in Track 1 at all; it serves a different purpose and is generally found in Track 2 or printed on the card itself. The card issuer identification number is also found in another format in Track 1, but it is not specifically highlighted as a unique element. Thus, the inclusion of the cardholder's name stands out as a key element within Track 1.
