PAYMENT CARD HAVING LIGHT-EMITTING DIODE INDICATORS COORDINATED WITH STORED PAYMENT APPLICATIONS

摘要

In an IC (integrated circuit) card, a selection signal is received from a user-actuatable switch to select between two different payment card accounts, each represented by a respective account indicator number stored in the IC component of the card. In response to the selection signal, a light-emitting diode indicator on the IC card is illuminated to indicate selection of a corresponding one of the payment card accounts.

主权项

1. An apparatus comprising:
a body; a first indicia printed on the body and representing a first payment card account; a first light-emitting diode (LED) mounted on the body in proximity to said first indicia; a second indicia printed on the body and representing a second payment card account different from the first payment card account; a second LED mounted on the body in proximity to said second indicia; a user-actuatable switch mounted on the body; and an integrated circuit (IC) supported by the body and operatively coupled to the first LED, the second LED and the user-actuatable switch; the IC storing a first account indicator number that corresponds to said first payment card account, and a second account indicator number that corresponds to said second payment card account; the IC programmed to allow a user to select between the first payment card account and the second payment card account by actuating the user-actuatable switch; the IC programmed to cause the first LED to be illuminated in response to the user selecting the first payment card account; the IC programmed to cause the second LED to be illuminated in response to the user selecting the second payment card account; the IC programmed to prevent the first account indicator number from being transmitted to a point of sale device at times when the first LED is experiencing a malfunction; and the IC programmed to prevent the second account indicator number from being transmitted to the point of sale terminal at times when the second LED is experiencing a malfunction.
