Payment systems that use payment cards, such as credit cards, debit cards, charge cards, or the like, employ a “PAN” (Primary Account Number) to refer to an associated account. For example, in the case of debit cards, the PAN may be a reference to a checking account at a financial service provider, such as a bank. Payment cards, and their associated PANs, enable convenient access to funds or a line of credit.
But with convenience comes the possibility of fraud. Large retailers are under the constant threat of attack from nefarious actors that attempt to steal PANs and other information in order to use them without the permission of the cardholder. When such mass attacks happen, however, financial institutions are able to respond by preventing stolen PANs from being used, issuing new PANs to each affected cardholder, and sending the new PAN in the form of another payment card. This consequently causes inconvenience for cardholders because the cardholders must wait for the new card to arrive before using the account associated with the new PAN. And more than causing inconvenience for the customer, it causes a loss in revenue for the financial institution.
Moreover, systems and methods are needed to prevent fraudulent use of PANs using mobile devices.
