Abstract

A device and method for waveform transmission of transaction card data to a merchant point-of-sale device are provided. The device includes a memory device for storing data, a processor, and a transmitter. The device is programmed to receive transaction card data that mimics data stored within a magnetic stripe associated with a transaction card, convert the transaction card data to a first data file for storage within the memory device, transmit the first data file to the transmitter, and transmit a first waveform from the transmitter to the POS device, wherein the first waveform includes changes in a magnetic field that represent the transaction card data.

First claim

What is claimed is:

1. A device for transmitting data to a merchant point-of-sale (POS) device, said device comprising:
a magnetic field generator for emitting changing magnetic fields, the magnetic field generator configured to:
receive data representing magnetic stripe data of a transaction card; and
generate changing magnetic fields for detection by a magnetic reader head of the POS device in response to receiving the data, the changing magnetic fields representing the magnetic stripe data of the transaction card;

wherein the changing magnetic fields are configured to be received remotely by the magnetic reader head of the POS device.

2. A device in accordance with claim 1 , wherein the magnetic field generator comprises an electromagnet configured to emit the changing magnetic fields.

3. A device in accordance with claim 2 , wherein the electromagnet comprises an inductor having one or more windings.

4. A device in accordance with claim 1 , wherein the changing magnetic fields are receivable by the magnetic reader head of the POS device when the magnetic field generator is placed a distance away from the POS device.

5. A device in accordance with claim 1 , wherein the changing magnetic fields are receivable by the magnetic reader head of the POS device without the magnetic field generator contacting the POS device.

6. A device in accordance with claim 1 , wherein the magnetic field generator comprises an electromagnet, the magnetic field generator configured to create the changing magnetic fields in response to receiving the data representing the magnetic stripe data of the transaction card, wherein the changing magnetic fields are emitted at sufficient strength that the magnetic reader head of the POS device is able to receive the changing magnetic fields when the transmitter is positioned in close proximity to but not in contact with the POS device.

7. A device in accordance with claim 1 , wherein the device further comprises a memory for storing a transaction card data file, the transaction card data file including a binary data file of the magnetic stripe data.

8. A device in accordance with claim 7 , wherein the device further comprises a processor in communication with the memory, the processor configured to convert the transaction card data file into the data representing the magnetic stripe data of the transaction card.

9. A device in accordance with claim 1 , wherein the device further comprises:
a magnetic stripe reader; and
a memory for storing a transaction card data file, wherein the magnetic stripe reader is configured to:
read the magnetic stripe data of the transaction card when the transaction card is swiped through the magnetic stripe reader, and
store the magnetic stripe data of the transaction card in the memory as a transaction card data file that represents the magnetic stripe data of the transaction card.

10. A device in accordance with claim 1 , wherein the device further comprises a memory for storing a transaction card data file, wherein the transaction card data file represents the magnetic stripe data of the transaction card and is received by the device through at least one of manual input, email, text message, Internet, and a removable storage device.

11. A device in accordance with claim 1 , wherein the device further comprises a memory for storing a transaction card data file, the transaction card data file communicated to the device, either directly or indirectly, from a financial institution.

12. A device in accordance with claim 1 , wherein the generated changing magnetic fields are configured to emulate a swiping of a magnetic stripe including the magnetic stripe data of the transaction card through the POS device.

13. A device in accordance with claim 1 , wherein the device is configured to be attachable to a mobile phone.

14. A method for remotely transmitting data from a magnetic field generator of a mobile device to a merchant point-of-sale (POS) device, said method comprising:
receiving data representing magnetic stripe data of a transaction card at the magnetic field generator;
positioning the mobile device a distance away from the POS device; and
emitting changing magnetic fields from the magnetic field generator in response to receiving the data, the changing magnetic fields emulating the magnetic stripe data of the transaction card at the POS device;
wherein the changing magnetic fields are of sufficient strength that a magnetic reader head of the POS device is able to remotely receive the changing magnetic fields without the magnetic field generator being in contact with the POS device.

15. A method in accordance with claim 14 , wherein the mobile device further comprises a memory, and wherein the method further comprises:
storing, within the memory, a transaction card data file, the transaction card data file representing the magnetic stripe data of the transaction card.

16. A method in accordance with claim 15 , wherein the transaction card data file is received by the mobile device from a financial institution.

17. A method in accordance with claim 14 , wherein the mobile device comprises a mobile phone that includes a processor and the magnetic field generator.

18. A method in accordance with claim 14 , wherein positioning the mobile device a distance away from the POS device further comprises positioning the magnetic field generator in close proximity to, but not in contact with, the POS device.

19. A mobile phone for transmitting data to a merchant point-of-sale (POS) device, said mobile phone comprising:
a memory; and
a magnetic field generator in communication with the memory; said mobile phone configured to:
provide data representing magnetic stripe data of a transaction card to the magnetic field generator; and
emit, via the magnetic field generator, changing magnetic fields for detection by a magnetic reader head of the POS device, the changing magnetic fields emulating the magnetic stripe data of the transaction card at the magnetic reader head,
wherein the magnetic field generator is configured to emit the changing magnetic fields at a strength to be received remotely by the magnetic reader head of the POS device.

20. A mobile phone in accordance with claim 19 , wherein the magnetic field generator comprises an electromagnet configured to generate the changing magnetic fields.

21. A mobile phone in accordance with claim 20 , wherein the electromagnet comprises an inductor having one or more windings.

22. A mobile phone in accordance with claim 19 , wherein the changing magnetic fields are receivable by the magnetic reader head of the POS device and emulate a magnetic stripe including the magnetic stripe data of the transaction card being swiped through the POS device when the mobile phone is placed a distance away from the POS device.

23. A mobile phone in accordance with claim 19 , wherein the changing magnetic fields are receivable by the magnetic reader head of the POS device without the mobile phone being placed into contact with the POS device.

24. A mobile phone in accordance with claim 19 , wherein the magnetic fields generator comprises an electromagnet, the magnetic fields generator configured to create the changing magnetic fields in response to receiving the data representing the magnetic stripe data of the transaction card, wherein the changing magnetic fields are emitted at a sufficient strength that the magnetic reader head of the POS device is
