Abstract

An apparatus and process for conducting a transaction with an electronic card that dynamically generates transaction specific data determines whether the transaction is being conducted with a smart card reader or with a magnetic stripe reader. A smart card reader mode is activated if the transaction is being conducted with a smart card reader; a magnetic stripe reader mode is activated if the transaction is being conducted with a magnetic stripe reader. The electronic card is activated from a reduced power mode to a full power mode after either the smart card reader mode or the magnetic stripe reader mode is activated and the dynamic field of data is not generated until the full power mode is activated.

Claims

1. A process for conducting a transaction with an electronic card, comprising the steps of:

determining whether the transaction is being conducted with a smart card reader or with a magnetic stripe reader;

activating either a smart card reader mode if the transaction is being conducted with the smart card reader or a magnetic stripe reader mode if the transaction is being conducted with the magnetic stripe reader;

generating a transaction specific dynamic field of data within the electronic card which includes a single use authentication code; and

either transmitting the transaction specific dynamic field of data to the smart card reader if the smart card reader mode is activated or transmitting the transaction specific dynamic field of data to the magnetic stripe reader by use of a magnetic stripe broadcaster only if the magnetic stripe reader mode is activated;

wherein the magnetic stripe broadcaster broadcasts a magnetic stripe signal that is a time varying and spatial varying magnetic field that is interpreted by a magnetic read head of the magnetic stripe reader as if originating from a standard magnetic stripe.

2. The process of claim 1 wherein the electronic card determines whether the transaction is being conducted with the smart card reader or with the magnetic stripe reader without use of a user input.

3. The process of claim 2 wherein the electronic card contains at least one sensor that detects the presence of a magnetic read head of the magnetic stripe reader that triggers activation of the magnetic stripe reader mode.

4. The process of claim 2 wherein the electronic card triggers activation of the smart card reader mode by physical contact between the electronic card and the smart card reader.

5. The process of claim 1 wherein the electronic card determines whether the transaction is being conducted with the smart card reader or with the magnetic stripe reader by use of a user input.

6. The process of claim 5 wherein the user input is provided by a user activation button.

7. The process of claim 6 wherein the user activation button is not a power on user input button.

8. The process of claim 1 wherein the electronic card is activated from a reduced power mode to a full power mode after either the smart card reader mode or the magnetic stripe reader mode is activated.

9. The process of claim 8 wherein the dynamic field of data is not generated until the full power mode is activated.

10. The process of claim 1 comprising the further step of selecting an account function from a plurality of account functions.

11. The method of claim 10 wherein the plurality of account functions includes at least one function from two different types of accounts selected from a group of different types of account functions comprised of a credit account, a debit account and a rewards points program account.

12. An apparatus, comprising:

a microprocessor that dynamically generates a transaction specific data packet;

at least one sensor for detecting a magnetic read head of a magnetic stripe reader;

a broadcaster that can broadcast a magnetic stripe signal that contains the transaction specific data packet;

a communications port that can communicate the transaction specific data packet to a smart card reader; and

electronics for activating either a smart card reader mode in which the transaction specific data packet is communicated to the smart card reader or a magnetic stripe reader mode in which the magnetic stripe signal is broadcast to the magnetic stripe reader;

wherein the magnetic stripe signal is a time varying and spatial varying magnetic field that is interpreted by the magnetic read head of the magnetic stripe reader as if originating from a standard magnetic stripe; and

wherein the electronic card is activated from a reduced power mode to a full power mode after either the smart card reader mode or the magnetic stripe reader mode is activated.

13. The apparatus of claim 12 wherein the electronic apparatus is a card compliant with a CR80 format.

14. The apparatus of claim 13 further comprising a user activation interface.

15. The apparatus of claim 14 wherein the user activation interface is not a power on user input button.

16. The apparatus of claim 15 wherein the user activation interface allows a user to select an account function from a plurality of account functions.

17. The apparatus of claim 16 wherein the plurality of account functions includes at least one function from two different types of accounts selected from a group of different types of account functions comprised of a credit account, a debit account and a rewards points program account.

18. The apparatus of claim 16 wherein a user display selection indicator indicates which of the plurality of account functions has been selected.

19. The apparatus of claim 16 further comprising a user communication output that provides a user with at least one piece of data necessary to complete a financial transaction involving the account function.

20. The apparatus of claim 12 wherein the transaction specific data packet is not generated until the full power mode is activated.
