Methods for risk management in payment-enabled mobile device

1. A payment-enabled mobile device, comprising:

at least one mobile device processor comprising a non-volatile memory storing a first counter and an associated first accumulator used for financial risk management purposes prescribed by an issuer of a payment card account, and storing a second counter and an associated second accumulator used for risk management purposes related to a lost or stolen mobile device prescribed by the issuer, 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; the transceiver operating under control by the at least one mobile device processor and the payment application program;

wherein the payment application program includes instructions configured by the issuer of the payment card account assigned to the user of the payment-enabled mobile device that cause the mobile device processor to:

detect when the payment-enabled mobile device is tapped on a reader;

determine that available prepaid funds are adequate for a current transaction based on a current value of at least one of the first accumulator and the first counter;

determine that a current value of the second counter and the second accumulator exceeds a lost and stolen risk management limit;

prompt the user to perform at least one cardholder verification method (CVM);

determine that the at least one CVM performed by the user is valid;

reset the second counter and the second accumulator;

detect that the mobile device has again been tapped on the reader by the user; and

consummate the transaction.

2. A method of operating a payment-enabled mobile device comprising:

detecting, by a mobile device processor of a payment-enabled mobile device, that the payment-enabled mobile device has been tapped on a reader by a user;

determining, by the mobile device processor, that available prepaid funds stored in a memory are adequate for a current transaction based on a current value of at least one of a first accumulator and a first counter;

determining, by the mobile device processor, that a current value of a second counter and a second accumulator stored in the memory exceeds a lost and stolen risk management limit;

prompting, by the mobile device processor, the user to perform at least one cardholder verification method (CVM);

determining, by the mobile device processor, that the at least one CVM performed by the user is valid;

resetting, by the mobile device processor, the second counter and the second accumulator;

detecting, by the mobile device processor, that the mobile device has again been tapped on the reader by the user; and

consummating, by the mobile device processor, the current transaction.

3. The method of claim 2 , wherein after detecting that the payment-enabled device has been tapped on a reader, further comprising:

determining, by the mobile device processor, that available prepaid funds stored in a memory are inadequate for a current transaction based on a current value of at least one of a first accumulator and a first counter;

declining, by the mobile device processor, the current transaction; and

prompting, by the mobile device processor, the user to top-up the prepaid funds amount.

4. The method of claim 2 , further comprising, after prompting the user to perform the at least one cardholder verification method (CVM), determining, by the mobile device processor, one of that the at least one CVM performed by the user is incorrect or that a predetermined time has elapsed without performance of the at least one CVM by the user;

prompting, by the mobile device processor, the user to perform at least CVM and incrementing a counter;

determining, by the mobile device processor, that the at least one CVM performed by the user is valid;

resetting, by the mobile device processor, the second counter and the second accumulator;

detecting, by the mobile device processor, that the mobile device has again been tapped on the reader by the user; and

consummating, by the mobile device processor, the current transaction.

5. The method of claim 2 , further comprising, after prompting the user to perform the at least one cardholder verification method (CVM):

determining, by the mobile device processor, that one of the at least one CVM performed by the user is incorrect or that a predetermined time has elapsed without performance of the at least one CVM by the user;

determining, by the mobile device processor, that the counter has reached a predetermined limit; and

declining, by the mobile device processor, the current transaction.
