Barclays do NOT accept bitcoin in the sense that they are not acting as a money transmitter in exchange to and from bitcoin / fiat.
I recently had my Barclays Business Account closed for no other reason than being involved in legitimate Bitcoin business. Much like every other bank, they are exploring blockchain tech, but they sure as hell aren't going to go into regulatory grey area's acting as a bitcoin money exchanger.
I hate it when the media blows stuff up like this, the news might as well not be news.
Yeah, I dont think any banks could accept bitcoin, since each of them have different principal in their system. The only key why bank approaching bitcoin is to study the blockchain, and they will make their own technology like blockchain, where they could make much profit from that.
