At first, I wanted to use NFC so that batteries would not be an issue but seeing as NFC is not making its way into US mobile devices as fast as I thought, BLE is a promising alternative. BLE is very convenient with its power usage & I am aiming to hopefully be able to have the finished product last for 2-3 years on its battery, possibly by employing flexible batteries (to be looked into!).
