Authorizing the use of a transaction card
First Claim
1. A method of authorizing the use of a transaction card having a set of ferromagnetic cells, comprising:
- generating processing power for manipulating the set of ferromagnetic cells;
receiving an authorization code as input from a user via at least one of a binary on/off switch array, a rotary dial array, and a biometric sensor;
comparing the input with a predefined value; and
putting an authorization mode on the set of ferromagnetic cells by manipulating the set of ferromagnetic cells based on the result of the comparison, wherein the authorization mode comprises legitimate information corresponding to the user.

Abstract
Embodiments of the present invention provide systems and methods for validating a user of a transaction card. Specifically, embodiments of the present invention utilize dynamic manipulation of a transaction card to authorize use of the card. In a typical embodiment, the cardholder approaches a magnetic reader with the card. The card is powered up by an embedded radio frequency identification (RFID) antenna in a magnetic field. The cardholder enters a user authorization code using an input method. The entry is compared against the predefined user authorization code. If the entry is invalid, an unauthorized code is put on virtual ferromagnetic cells (VFC) embedded in the card. If the entry is valid, legitimate card information is put into the VFC. When the card is swiped, magnetic information on the VFC is coupled, amplified, and recorded to the reader. After cardholder use, the VFC are reset to a random or unauthorized mode.
