Abstract: An authentication and payment system for paying a supplier via a network may include a non-transitory computer readable storage medium having program logic stored thereon having a code for an authentication and payment application executable by a processor of a computing device. The code may be programmed to perform a step of receiving a first set of specific data elements from a payer regarding an authorized purchase by the payer from the supplier. The code may be further programmed to receive a second set of specific data elements from the supplier. If the first set of specific data elements matches at least a portion of second set of specific data elements, the code may be programmed to generate and send a single-use number to the supplier. The single-use number may be usable as a credit card number for only one purchase.
