Abstract

An electronic wallet which is biometrically secured stores credit card and other information. A biometric sensor prevents the electronic wallet from being used by the user who does not have permission to use the wallet. A rewriteable card is inserted into a slot of the wallet in order to have credit card information placed on the card. After the card is used the information is erased from the card when it is placed back in the slot in the electronic wallet.

Claims

1. An electronic wallet comprising

a housing including a slot;

a display secured to said housing and visible on an exterior surface of said housing for displaying information stored in the electronic wallet;

a biometric sensor mounted on an exterior surface of said housing, said biometric sensor being used to verify the identity of a user of the electronic wallet;

a card including a rewritable memory for temporarily storing information, said card having dimensions such that said card can fit at least partially within said slot;

a controller positioned within said housing for verifying the identity of the user through information obtained by said biometric sensor and for causing information to be written to said rewritable memory on said card.

2. The electronic wallet of claim 1 comprising a flash memory positioned within said housing for storing information.

3. The electronic wallet of claim 1 wherein said rewritable memory on said card is a magnetic strip and wherein said electronic wallet further comprises a magnetic strip reader for acquiring information from magnetic strips on cards inserted into said slot.

4. The electronic wallet of claim 1 further comprising a smart card controller that encrypts data read from magnetic strips of said cards inserted into said slot.

5. The electronic wallet of claim 1 further comprising a magnet for erasing said rewritable memory on said card when said card is inserted into said slot.

6. The electronic wallet of claim 1 wherein said biometric sensor is a fingerprint sensor.

7. The electronic wallet of claim 1 wherein said controller backs up data stored on said electronic wallet by dividing said data to be backed up into several components and storing at least two of said components in different databases.

8. The electronic wallet of claim 1 further comprising an audio input/output circuit for receiving audio signals from a user and for generating sound signals from said electronic wallet.

9. The electronic wallet of claim 5 wherein said magnet will erase said rewritable memory even if said electronic wallet is not powered on.

10. A method of using a secure electronic device, comprising:

storing credit card magnetic strip information as encrypted data within a portable electronic device;

biometrically enabling decryption of said encrypted data by presenting biometric data to a biometric sensor incorporated in said portable electronic device;

decrypting said credit card magnetic strip data;

writing said credit card magnetic strip data to a magnetic strip on a magnetically reconfigurable card through a card writing interface incorporated in said electronic device; and

removing said magnetically reconfigurable card from contact with said electronic device.

11. The method of using a secure electronic device of claim 10 further comprising the step of.

returning said magnetically reconfigurable card into mechanical contact with said portable electronic device in such a way as to automatically erase said magnetically reconfigurable card sufficiently so that said card is no longer readable by typical consumer-transaction magnetic card readers.

12. The method of using an a secure electronic device of claim 11 wherein said automatic erasing is accomplished by passing the magnetic strip of said reconfigurable card through a magnetic field produced by a permanent magnet.

13. The method of using an a secure electronic device of claim 11, wherein said step of returning said reconfigurable card to contact with said electronic device comprises slidably inserting said reconfigurable card into said electronic device, and wherein said automatic erasing is enabled through detection of a mechanical feature of said reconfigurable card.
