1. An apparatus forming a portable identification card which can be read using a magnetic swipe card reader, comprising:
- a magnetic stripe for storing information;
an input device adapted for a user to enter authentication data;
a memory for storing reference data;
a processor configured to compare the authentication data entered by the user to the reference data stored in the memory to determine whether the authentication data entered by the user is correct authentication data;
a sensor assembly configured to detect when the card is swiped through the magnetic card reader;
a jammer adapted to emit jamming signal which causes the magnetic card reader to consider the magnetic stripe to be invalid when the card is swiped without first entering the correct authentication data;
a power source adapted to supply power to the processor, the sensor assembly, and the jammer;
wherein the processor is further configured to count sequential entries in which the authentication data entered by the user failed to match the reference data, and wherein the jammer is further adapted to emit an erasing signal which erases a portion of the magnetic stripe when the count of sequential entries exceeds a predetermined number.

Abstract
Apparatus forming a portable charge, debit or similar identification card which can be read using a magnetic card reader and methods for securing information are described. The preferred apparatus includes a magnetic stripe for storing information, a jamming assembly configured to emit a jamming signal which temporarily renders at least a portion of the magnetic stripe unreadable when the card is swiped through the card reader without first entering correct authentication data, and a power source adapted to supply power to the jamming assembly. Other features are also disclosed.

3. An apparatus forming a portable charge, debit or similar identification card which can be read using a magnetic card reader, comprising:
-
a magnetic encoded code for storing information; a jamming assembly configured to emit a jamming signal which at least temporarily renders a portion of the magnetic stripe unreadable when the card is passed through a card reader without first entering correct authentication data; a power source adapted to supply power to the jamming assembly; wherein the jamming assembly is further configured to emit an erasing signal which erases a portion of the magnetic stripe once a predetermined number of incorrect authentication data entries have been sequentially entered.

-
a magnetic encoded code for storing information; a jamming assembly configured to emit a jamming signal which at least temporarily renders a portion of the magnetic stripe unreadable when the card is passed through a card reader without first entering correct authentication data; a power source adapted to supply power to the jamming assembly; wherein the jamming system is further configured to emit an erasing signal which erases a portion of the magnetic stripe once the card has been sequentially passed through the card reader a predetermined number of times without entry of the correct authentication data.
