Abstract
Various technologies related to one-time credit card numbers are presented. One-time credit card numbers can originate from a customer device and be independently generated by the customer device without online communication with an issuer. Signed transaction details can also be sent, providing non-repudiation of the purchase transaction. Merchant infrastructure need not be changed to accommodate the one-time credit card numbers. The technologies can be particularly resilient to replay, forgery, man-in-the-middle, and guessing attacks for credit card number generation or other usage by an attacker.
