The protocol we used in this process was MMS!
The reason why we choose to do it this way is because over 90% of the uk have access to a mobile phone- But also its simple and if you have free texts its free! but you can send it from ANYWHERE you dont need to run off 3g or wi-fi to do it.
If a person is beside you you can send it Via Bluetooth and Blutooth is also free!
