It was always heading this way, the next thing will be implants, not just for banking but for everyday tasks, with the whole internet of things, Amazon Echo type devices etc, it won't be long before you have a chip or swallow a tiny chip that will then act as an NFC communicator to do such things as pay, open your car door and so on. Exciting and yet quite scary times we are in.
One guy has already put a RFID chip in his arm which to me is kind of crazy and unnecessary.

This is the future. Maybe we can imprint a device for Bitcoin too. Where just scanning an NFC we would be able to buy something with it. I think this chip we are talking about is also one of the advances in finance. However, it's still low tech if you ask me. It just a little security upgrade to the old system and it does not really improve finance as it is.
