So if I get this, I will have to worry about potentially paying anyone that approaches my wrist with something that could contain a radio? Someone should create another startup that embeds tiny contactless credit card machines on wrists lol.

Same as a contactless credit card. There are readers on the darknet that can read 10 cards per-second.

But at least you could put your card in a protective wallet, and card company will refund any fraudulant transactions.

An NRF blocking sleeve perhaps? :D

You could by a blocking watch that selectively unblocks transactions when authorized. Problem solved.

At that point you may as well just use a smart watch for payments.

[spicybright]

You need to be very close to trigger a read, so you'd pretty much have to take the watch off to scan.

By that same token, doesn't someone have to get really close to steal it?
