Hm, interesting. Indeed this news was published years ago but for some reasons several news agencies, CNBC, CCN, DiarioBitcoin and Kriptoparahaber have reposted it recently. There's even earlier article on the subject published in Nov 2014 by The Telegraph:
https://www.telegraph.co.uk/technology/news/11220577/Man-embeds-computer-chips-in-hands-to-store-Bitcoin.html
I see two possible reasons why some old news is being "rediscovered" like this one.First is that media considered people have short term memory so they can sell the same story several times,like a same candy in a different package.Second reason is maybe in that someone wants to start mass production of such chips and wants to examine what is the opinion of the market today.
There is no doubt that this technology comes into wide use,millions would accept it even today-at least ones that always forget the keys from home or car.
