determining, with at least one processor, transaction data corresponding to the payment transaction;
based upon the transaction data, determining, with at least one processor, whether the at least one transaction limitation parameter has been met;
in response to determining that the at least one transaction limitation parameter has been met, terminating, with at least one processor, the biometric verification process; and
