ABSTRACT
Magnetic stripe cards are still used in many applications—cash withdrawal, credit/debit prepayments, storage of currency or tokens, access control, and so on—particularly in the United States. This chapter surveys the security measures to protect payments at Point-of-Sale Terminals and online. The efforts of the Payment Card Industry Security Standards Council are highlighted. Online security measures are presented next, including monitoring criteria to detect possible fraud in real time as well as some new architectures such as the 3-D Secure initiative. This chapter concludes with a description of U.S. efforts to migrate to integrated circuit payment cards, using the Europay, MasterCard, and Visa (EMV) specifications.
