I wonder if you could use Bluetooth Low Energy instead of WiFi as the power saving can last years. iBeacons have the potential to last years on a single battery. Probably not ideal for transferring large amounts of information though.

You could make the data available elsewhere in encrypted form and use the Bluetooth device to distribute the key and the URL where the data can be found.
