Abstract

Embodiments of the invention may use a first accelerometer to measure first acceleration data of a first device. Other interaction data, including time data and geographic location data, generated by the first device may also be recorded. First acceleration data is compared by a remote server computer to second acceleration data generated by a second accelerometer in a second device. If the first and second accelerometer data are substantially equal, it can be determined that the devices have interacted and communications can be initiated. After communications are initiated, a financial transaction is conducted. Accelerometer data may be stored and/or used as part of the authentication process in a payment processing network. Other embodiments of the invention use the accelerometer to generate movement security data to make financial transaction more secure. Accelerometer data is used for authentication, security, encryption, session keys, non-repudiation, or fraud protection.

Claims

1. A method of conducting a financial transaction comprising:

receiving first accelerometer data from a first device, wherein the first device comprises a first processor and a first accelerometer coupled to the first processor;

receiving second accelerometer data from a second device, wherein the second device comprises a second accelerometer and a second processor coupled to the second accelerometer;

receiving a payment amount from at least one of the first device or the second device;

determining when the first device moves towards the second device with a server computer using accelerometer data from the first device and the second device; and

if the first and second devices moves towards each other, initiating the transmission of an authorization request message to a first issuer, wherein the first issuer approves or does not approve the authorization request message.

2. The method of claim 1 further comprising:

receiving timestamp data from at least one of the first or second device.

3. The method of claim 2 further comprising:

receiving location data from at least one of the first or second device.

4. The method of claim 3 further wherein the location data is used for fraud or risk analysis.

5. The method of claim 3 further wherein the timestamp data is used for fraud or risk analysis.

6. The method of claim 1 wherein the first device is associated with a first transaction account issued by the first issuer and the second device is associated with a second transaction account issued by a second issuer.

7. The method of claim 6 wherein, if the first issuer approves the authorization message, the payment amount is debited from the first transaction account and deposited into the second transaction account.

8. The method of claim 7 wherein the second transaction account is a credit account.

9. The method of claim 6 wherein the second device is associated with a third transaction account.

10. The method of claim 9 wherein, if the first issuer approves the authorization message, the payment amount is debited from the first transaction account and deposited into the second transaction account or the third transaction account, as selected by an operator of the second device.

11. The method of claim 1 wherein initiating the transmission of an authorization message to the first issuer comprises sending a message to an acquiring bank.

12. A non-transitory computer readable medium, comprising code for implementing the method of claim 1.

13. A server comprising the non-transitory computer readable medium of claim 12.

14. A phone comprising:

a first processor;

a first accelerometer coupled to the first processor;

a first antenna coupled to the first processor; and

a non-transitory computer readable medium coupled to the first processor, the computer readable medium comprising code for implementing a method comprising;

prompting a user of the first phone to move the first phone towards a second phone, wherein the second phone comprises a second accelerometer and a second processor coupled to the second accelerometer,

generating and storing first interaction data associated with the movement of the first phone towards the second phone,

sending, with the first antenna, payment information to a remote server computer, and

sending, with the first antenna, the first interaction data to the remote server computer for comparison against second interaction data from the second phone, wherein the first and second interaction data is used to initiate the generation of an authorization message.

15. The first phone of claim 14 wherein payment information comprises a payment amount, payor information, and payee information.

16. The first phone of claim 15 wherein the financial transaction is conducted between a payor transaction account associated with one of the first or second phones, and a payee transaction account associated with the other of the first or second phones.

17. The first phone of claim 16 wherein the payment amount is debited from the payor transaction account and credited to the payee transaction account.

18. The first phone of claim 17 wherein the payee transaction account is a debit or credit account.

19. The first phone of claim 17 wherein the payee transaction account is an interest bearing account.

20. A method of conducting a financial transaction comprising:

prompting a first user of a first device to move the first device to indicate the first user'"'"'s intent to conduct a financial transaction, wherein the first device comprises a first processor and a first accelerometer coupled to the first processor;

recording first movement security data representative of the first user'"'"'s movement using the first accelerometer;

prompting the first user to move the first device towards a second device, operated by a second user, to indicate the first user'"'"'s intent to interact with the second device and conduct a financial transaction with the second user;

recording first interaction data representative of the movement of the first device towards a second device using the first accelerometer;

transmitting the first movement security data to a remote server computer; and

transmitting the first interaction data to the remote server computer for comparison against second interaction data generated by the second device, wherein the first and second interaction data are used to conduct a financial transaction.

21. The method of claim 20 wherein the movement security data includes a measurement of time representing the duration of the movement

22. The method of claim 20 wherein the movement security data includes location data and time data.

23. The method of claim 20 wherein prompting the first user of the first device to move the first device, further comprises prompting the first user to move the first device for at least a pre-determined amount of time.

24. The method of claim 20 wherein the first movement security data and the first interaction are stored in a database for transaction verification.

25. The method of claim 20 wherein the first movement security data is used as a unique seed for encryption of data related to the financial transaction.

26. The method of claim 20 wherein the prompting of the first user to move the first device to indicate the first user'"'"'s intent to conduct a financial transaction comprises prompting the user to move the first device in a sequence of pre-determined movements.

27. A non-transitory computer readable medium, comprising code for implementing the method of claim 20.

28. A server comprising the non-transitory computer readable medium of claim 27.
