Abstract
Abstract A system for changing the activation status of a selected data card such as a charge card by broadcasting an appropriate RF signal. An antenna embedded in the card detects and decodes the signal, and operates a transducer which changes the card appearance, alters magnetic stripe information, or alters the information contained within the card.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
122 words
An alterable wallet-size data card of the type including a magnetic stripe, the card being capable of responding to a unique RF signal transmitted from a remote source, said data card comprising: antenna means in the card for detecting said unique RF signal; means for decoding said unique RF signal upon detection thereof; transducer means for selectively altering a characteristic of the data card indicative of its status; and means for operating said transducer means, in response to operation of said decoding means, to alter the status of the data card; wherein said transducer means comprises a magnetic coil positioned over said magnetic stripe, said magnetic coil focusing flux over a portion of said magnetic stripe when said transducer means is operative.
