Abstract:
1. A computer-implemented method, comprising: issuing a transaction number generator to a user, wherein the transaction number a plurality of single-use transaction numbers including a first single-use transaction number, wherein each single-use transaction number includes a routing number, an account number, and a one-time password, wherein the transaction number generator slows down generation of the one-time password if an incorrect personal identification number (PIN) is entered; installing a transaction number validator capable of generating the same plurality of onetime passwords, wherein the transaction number validator executes on a processor of a computer system; receiving, at the transaction number validator, the first single-use transaction number from the transaction number generator via a network; generating, at the transaction number validator, an expected one-time password in response to the first single-use transaction number; and generating a validation result using the processor of the computer system, within the transaction number validator, wherein generating a validation result includes comparing the one-time password of the first single-use transaction number with the expected one-time password in order to generate the validation result; wherein each single-use transaction number is formatted such that its respective routing number can be used to route the single-use transaction number to the transaction number validator.
