Abstract
A credit card is provided that may include a credit card number, where at least a portion of the credit card number changes periodically. A magnetic emulator and/or magnetic stripe encoder may be provided to communicate at least a portion of the information needed to complete a credit card transaction to a credit card reader. For example, a magnetic emulator may be provided about a magnetic stripe so that the magnetic emulator communicates the information that changes and the magnetic stripe communicates the information that does not change. In doing so, the amount of power used by a credit card may be reduced with respect to a credit card that communicates, for example, all of the information with a magnetic emulator.
