A method and system for facilitating, via a first device, an electronic financial transaction with a second device having limited network connectivity. The method includes the first device detecting initiation of a financial transaction with the second device. The financial transaction is remotely processed by a transaction service. The method further includes facilitating an establishment of a data pipe that directly connects the first device and the second device to enable the second device to exchange transaction data with the transaction service, via the first device operating as an intermediary device. In response to the data pipe being established, the first device routes, via the primary connection to the transaction service, all transaction data received from the second device over the data pipe.
