Abstract: Disclosed is a system and method that provides a merchant associated with a point of sale (POS) system and a consumer associated with a portable computing device (PCD) to complete a purchase transaction without transmitting or presenting confidential payment credentials. In an exemplary embodiment sound is used to transmit data between the POS and the PCD. A payment request is rendered on the PCD. The consumer reviews and authorizes via a unique cryptographic signature. The merchant approves via addition of its unique cryptographic signature. A remote service in communication with the POS verifies the signatures via previously registered public keys. The transaction is then settled to a consumer account. Confirmation is returned to the POS and PCD. Advantageously the transaction is commenced and completed without the PCD being online. Further the consumer payment credentials are not stored on the PCD or transmitted from the PCD to the merchant POS system.
