A system allows consumers the ability to remotely transmit order and/or payment preference data to a vendor to facilitate sales transactions. A personal transmitter or key fob functions to transmit a signal to the vendor when the customer approaches the vendor, which signal comprises preferred order information for vendor processing. The vendor may acknowledge order receipt, generate the order, and automatically submit the transaction for payment through a secure connection. A web site acknowledges receipt of the payment request, retrieves specific transaction information for the target vendor, and processes the payments electronically. Customer information, vendor preferences and encrypted Customer payment specific pointers are downloaded to the personal transmitter on an ongoing basis and stored as encrypted data. If multiple vendors are within the proximity of the consumer, the transmitter will signal an error and list the vendors to the consumer, from which list the target vendor may be selected.
