Electronic cards include a
package having vertical and horizontal dimensions of a standard
credit card, and including first and second opposing faces. A
flat panel display extends over the first face. A dynamic magnetic
encoder is provided on the second face. A
user input device also is provided on the
package. A processor is provided in the
package that is configured to display a substantially full size image of a
credit card on the
flat panel display, and to control the dynamic magnetic
encoder to provide magnetic stripe information for the
credit card, in response to user selection of the credit card via the
user input device. Accordingly, the look (image) of a credit card can be emulated, as well as the magnetic stripe information that would be provided by the credit card, in response to user selection of the credit card.
