Nfc implant paying question

Hello so I have a question that have probably been asked a few thousand times. I never thought paying with a nfc implant was possible but I recently came across this video and it just blew me away. I know its buzzfeed and they are not always the most respected source but this means its possible. So my question is has anyone here found a way to do this, or found a way to do something like this. Sorry if this question is been asked a lot, or if this question is just stupid

It’s all here including info on that video.
