An electronic wallet system 1 comprises an electronic wallet 3 on a mobile device 5 and enables payment transactions between a financial institution 7 associated with a user's mobile wallet 3 and a financial institution 9 associated with a retailer's point of sale terminal 11. The mobile wallet 3 may be downloaded as an application software module from the payment service issuer system 13. In use, the electronic wallet receives a request for a transaction and a data communication session is established using a first communication protocol. When it is determined that the data communication session is not available to complete the transaction, the remote system transmits data to complete the transaction using a second communication protocol which is different to the first. The electronic wallet receives the transmitted data and processes the received data to complete the transaction. |
