A server facilitates a transaction between a first wireless device and a second wireless device. An identifier associated with the second wireless device has been sent to the first wireless device using a short range wireless connection; the server receives the identifier. The server then determines location information associated with both the first and said second wireless devices. If the location of the first and second wireless devices is appropriate for authorizing the transaction, the server then determines authentication information relating to the second wireless device. The server then provides authorization to the first or second wireless device to proceed with the transaction. The authorization may be based at least in part upon the identifier, the authentication information and the locations of said first and second wireless devices.
