Methods for risk management in payment-enabled mobile device
First Claim
Patent Images
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;
determining, by comparing the first transaction context data with the second transaction context data in the mobile device, that the second tap is for the same transaction as the first tap;
determining, by the mobile device, that one of a PIN verification status flag or a user acknowledgment status flag has been set; and
transmitting, by the mobile device to the POS terminal, a payment card account number to consummate the transaction.

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.

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; anda nonvolatile memory for implementing a first accumulator and a second accumulator, said second accumulator different from said first accumulator, and for implementing a first counter associated with the first accumulator and a second counter associated with the second accumulator; said processor controlled by the payment application program to; detect a tap on a proximity reader component; refer to a count tracked by the first counter regarding payment usage aspects and stored in the first accumulator to determine whether to decline a current transaction; and refer to a count tracked by the second counter regarding risk management aspects and stored in 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. - View Dependent Claims (5)

6. 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; transmitting, by the POS terminal to the payment-enabled mobile device, instructions to perform 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 by the POS terminal in response to the second indication. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. 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. - View Dependent Claims (14, 15)

16. 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; in response to receiving the transaction acknowledgment; setting an acknowledgement status flag in the payment-enabled mobile device; 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 acknowledgement status flag 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. - View Dependent Claims (17, 18)

19. A method of operating a payment-enabled mobile device, the method comprising:
-
receiving, in the device, pre-transaction user input from a user of the device; storing, in the device, an indication of the pre-transaction user input; detecting by the device that it is tapped on a proximity reader component in connection with a purchase transaction; reading said indication; and in response to said indication, consummating the purchase transaction without requiring the device to be tapped a second time on the proximity reader component; wherein the user input includes at least one of (a) a transaction acknowledgment signal and (b) entry of a personal identification number (PIN). - View Dependent Claims (20, 21)
