A first message is received at a wallet service provider. The first message contains transaction detail and transaction context data. A second message is also received at the wallet service provider. The second message contains a copy of the transaction detail data and a copy of the transaction context data. The wallet service provider may verify that the data copies match the original data. One of the messages may be received from a payment-enabled mobile device. The other message may originate from a merchant. |
