Abstract

A mobile telephone includes conventional features such as a housing, a speaker, a microphone, an antenna by which voice signals are transmitted and received, and electronic circuitry which handles the sending and receiving of voice signals. The mobile telephone includes two more antennas, one adjacent the front surface of the housing, and the other adjacent the rear surface of the housing. In addition, the mobile telephone includes a payment circuit that is mounted in the housing and coupled to the latter two antennas. The payment circuit is operative to selectively receive a customer'"'"'s payment card account number via one or both of the latter two antennas.

Claims

1. A mobile telephone having contactless payment functionality, the mobile telephone comprising:

a housing having a front surface and a rear surface that is opposite to the front surface;

a microphone mounted in or on the housing;

a speaker mounted in or on the housing;

a first antenna mounted in or on the housing;

mobile telephone receive/transmit circuitry mounted in the housing;

the mobile telephone receive/transmit circuitry coupled to the microphone, the speaker and the first antenna;

the mobile telephone receive/transmit circuitry operative to;

transmit, via the first antenna, voice signals generated by the microphone; and

reproduce, via the speaker, voice signals received via the first antenna;

a touch screen or keypad mounted at the front surface of the housing;

a second antenna adjacent the front surface of the housing;

a third antenna adjacent the rear surface of the housing; and

a payment circuit mounted in the housing and coupled to the second and third antennas, the payment circuit operative to receive a customer'"'"'s payment card account number, via one or both of the second and third antennas.

2. The mobile telephone of claim 1, wherein said second and third antennas are loop antennas.

3. The mobile telephone of claim 2, wherein:

the mobile telephone includes a keypad mounted at the front surface of the housing; and

the second antenna loops around the keypad.

4. The mobile telephone of claim 2, wherein:

the mobile telephone includes a battery mounted adjacent the rear surface of the housing, the battery for supplying power to the mobile telephone receive/transmit circuitry; and

the third antenna is mounted on the battery.

5. The mobile telephone of claim 1, wherein:

the payment circuit is coupled to the mobile telephone receive/transmit circuitry; and

the payment circuit and the mobile telephone receive/transmit circuitry selectively cooperate to transmit a purchase transaction authorization request via the first antenna, the purchase transaction authorization request including the customer'"'"'s payment card account number received via one or both of the second and third antennas.

6. The mobile telephone of claim 1, further comprising:

a display mounted at the front surface of the housing.

7. The mobile telephone of claim 1, wherein the payment circuit stores a payment card account number and is operative to selectively transmit the stored payment card account number, via one or both of the second and third antennas, in response to receiving an interrogation signal from a merchant device.

8. A mobile telephone having contactless payment functionality, the mobile telephone comprising:

a housing having a front surface and a rear surface that is opposite to the front surface;

a microphone mounted in or on the housing;

a speaker mounted in or on the housing;

a first antenna mounted in or on the housing;

mobile telephone receive/transmit circuitry mounted in the housing;

the mobile telephone receive/transmit circuitry coupled to the microphone, the speaker and the first antenna;

the mobile telephone receive/transmit circuitry operative to;

transmit, via the first antenna, voice signals generated by the microphone; and

reproduce, via the speaker, voice signals received via the first antenna;

a touch screen or keypad mounted at the front surface of the housing;

a second antenna adjacent the front surface of the housing;

a third antenna adjacent the rear surface of the housing;

a payment circuit mounted in the housing; and

a switching circuit coupled to the payment circuit and to the second and third antennas for selectively coupling the payment circuit to a selected one of the second and third antennas;

the payment circuit operative to receive a customer'"'"'s payment card account number, via the selected one of the second and third antennas.

9. The mobile telephone of claim 8, wherein:

the switching circuit is coupled to the touch screen or keypad and is responsive to user input received via the touch screen or keypad to select one of the second and third antennas to be coupled to the payment circuit.

10. The mobile telephone of claim 8, wherein said second and third antennas are loop antennas.

11. The mobile telephone of claim 10, wherein:

the mobile telephone includes a keypad mounted at the front surface of the housing; and

the second antenna loops around the keypad.

12. The mobile telephone of claim 10, wherein:

the mobile telephone includes a battery mounted adjacent the rear surface of the housing, the battery for supplying power to the mobile telephone receive/transmit circuitry; and

the third antenna is mounted on the battery.

13. The mobile telephone of claim 8, wherein:

the payment circuit is coupled to the mobile telephone receive/transmit circuitry; and

the payment circuit and the mobile telephone receive/transmit circuitry selectively cooperate to transmit a purchase transaction authorization request via the first antenna, the purchase transaction authorization request including the customer'"'"'s payment card account number received via the selected one of the second and third antennas.

14. The mobile telephone of claim 8, further comprising:

a display mounted at the front surface of the housing.

15. The mobile telephone of claim 8, wherein the payment circuit stores a payment card account number and is operative to selectively transmit the stored payment card account number, via one or both of the second and third antennas, in response to receiving an interrogation signal from a merchant device.

16. A method of operating a mobile telephone, the method comprising:

receiving antenna selection input from a user of the mobile telephone; and

selecting an antenna for connection to a payment circuit in response to the antenna selection input, the antenna selected from among a plurality of antennas including a front side antenna and a rear side antenna, the front side antenna adjacent a front side of the mobile telephone, the rear side antenna adjacent a rear side of the mobile telephone, the payment circuit operative to selectively receive a customer'"'"'s payment card account number via the selected antenna.

17. The method of claim 16, wherein the antenna selection input is received via a keypad.

18. The method of claim 16, wherein the antenna selection input is received via a touch screen.

19. The method of claim 16, wherein the front side antenna and the rear side antenna are loop antennas.

20. The method of claim 16, further comprising:

transmitting the customer'"'"'s payment card account number via an antenna other than the front side antenna and the rear side antenna.
