Abstract

A payment-enabled mobile device such as a “smart phone” incorporates risk management features that are applicable to its use in contactless payment transactions. Some features may govern when verification of the cardholder'"'"'s identity is required for consummation of the current transaction. The features may be configurable by the payment card account issuer and/or the user of the mobile device.

Claims

1. A method of operating a payment-enabled mobile device, the method comprising:

receiving in the mobile device, during a first tap of the mobile device, for a current transaction on a proximity reader component of a point of sale (POS) terminal, first transaction context data for the current transaction from the proximity reader component;

receiving in the mobile device, during a second tap of the mobile device, for the current transaction on the proximity reader component, second transaction context data for the current transaction from the proximity reader component; and

comparing the first transaction context data with the second transaction context data in the mobile device.

2. The method of claim 1, wherein the payment-enabled mobile device is programmed to decline the current transaction in response to the second transaction context data not matching the first transaction context data.

3. The method of claim 1, wherein the transaction context data includes transaction amount data and a currency indicator.

4. A payment-enabled mobile device, comprising:

at least one processor;

a memory, in communication with the at least one processor, and storing a payment application program;

an antenna;

a transceiver, coupled to the antenna, for exchanging wireless signals via the antenna with a proximity reader component of a point of sale (POS) terminal;

the transceiver operating under control by the at least one processor and the payment application program; and

a nonvolatile memory for implementing a first accumulator and a second accumulator, said second accumulator different from said first accumulator;

said processor controlled by the payment application program to;

refer to the first accumulator to determine whether to decline a current transaction; and

refer to the second accumulator to determine whether to require a user of the mobile device to enter a personal identification number (PIN) as a condition of consummating the current transaction.

5. The payment-enabled mobile device of claim 4, wherein:

the nonvolatile memory also implements a first counter and a second counter; and

said processor is controlled by the payment application program to;

refer to the first counter to determine whether to decline the transaction; and

refer to the second counter to determine whether to require a user of the mobile device to enter a PIN as a condition of consummating the current transaction.

6. The payment-enabled mobile device of claim 4, wherein:

each of said accumulators is configurable between a temporary accumulation mode and a permanent accumulation mode;

in the temporary accumulation mode, a transaction amount for a current transaction is registered into said each accumulator before considering a value of said each accumulator with respect to the current transaction; and

in the permanent accumulation mode, the transaction amount for the current transaction is registered into said each accumulator only in response to consummation of the current transaction.

7. A payment-enabled mobile device, comprising:

at least one processor;

a memory, in communication with the at least one processor, and storing a payment application program;

an antenna; and

a transceiver, coupled to the antenna, for exchanging wireless signals via the antenna with a proximity reader component of a point of sale (POS) terminal;

the transceiver operating under control by the at least one processor and the payment application program;

wherein the payment application program has a state in which the payment application program declines all purchase transactions until a user of the payment-enabled mobile device completes a process in the payment-enabled mobile device for changing a personal identification number (PIN) stored in the payment-enabled mobile device.

8. The payment-enabled mobile device of claim 7, wherein the payment-enabled mobile device is a mobile telephone that includes a microphone and a speaker.

9. The payment-enabled mobile device of claim 7, wherein the process for changing the PIN includes resetting a flag stored in the payment-enabled mobile device.

10. A method of performing a purchase transaction, the method comprising:

receiving transaction information in a point of sale (POS) terminal, the transaction information including a transaction amount for a current transaction;

determining in the POS terminal, based on the transaction amount, that a cardholder verification process is required for the current transaction;

receiving a first indication in the POS terminal, from a payment-enabled mobile device, that the payment-enabled mobile device is capable of performing the cardholder verification process;

receiving a second indication in the POS terminal that the payment-enabled mobile device has verified a personal identification number (PIN) entered into the payment-enabled mobile device for the current transaction by a user of the payment-enabled mobile device; and

consummating the current transaction of the POS terminal in response to the second indication.

11. The method of claim 10, wherein the second indication is a digital signature generated by the payment-enabled mobile device.

12. The method of claim 11, wherein the digital signature is verified by the POS terminal.

13. The method of claim 10, wherein the second indication is a cryptographically generated dynamic security code.

14. The method of claim 13, wherein the POS terminal forwards the cryptographically generated dynamic security code in an authorization request that is relayed to an issuer of the user'"'"'s payment card account.

15. The method of claim 10, wherein the first and second indications are both provided by a single indication, from the payment-enabled mobile device, of successful pre-entry of the PIN by the user.

16. The method of claim 15, wherein said PIN pre-entry is valid for a predetermined number of additional transactions or for additional transactions during a predetermined period of time.

17. A method of operating a payment-enabled mobile device, the payment-enabled mobile device including a display device for displaying information to a user, the method comprising:

receiving, in the payment-enabled mobile device, input from the user, the input comprising a personal identification number (PIN);

verifying the PIN in the payment-enabled mobile device;

in response to verifying the PIN;

setting a PIN-verified status in the payment-enabled mobile device; and

initiating a count-down function in the payment-enabled mobile device, the count-down function for indicating a future point in time at which the PIN-verified status will expire; and

providing a visual count-down display to the user via the display device, the visual count-down display sequentially updated by the payment-enabled mobile device to present current values of the count-down function.

18. The method of claim 17, further comprising:

displaying a button indication on the display device, the button indication for allowing the user to extend the future point in time at which the PIN-verified status will expire.

19. The method of claim 18, further comprising:

detecting, in the payment-enabled mobile device, actuation of the button indication by the user;

in response to the actuation, extending the future point in time at which the PIN-verified status will expire; and

restarting the visual count-down display to reflect the extending of the future point in time.

20. A method of operating a payment-enabled mobile device, the payment-enabled mobile device including a display device for displaying information to a user, the method comprising:

receiving, in the payment-enabled mobile device, input from the user, the input comprising a transaction acknowledgment signal;
