I thought that what was being proposed was just a credit or debit card where you have a BTC denominated bank account.
I thought so too, until this flight of fancy about the terminal appeared.
Incidentally, there are solutions involving MasterCard-branded debit cards, loaded via bitcoin. I had one for a bit, until the issuing bank got scared off by our insane US finance regulations. Last I looked, they were still available to people who live outside the USA.
