when I travel to other country, the first thing after arrive is exchange some money,
then buy a mobile card, and a traffic card.
the exchanger's rate is really very high at airport.
so if a shop can sell mobile card and traffic card with bitUSD,
it will be very helpful, I don't need to exchange at airport.
I only need print a paper wallet, scan the paper, and get my mobile card and traffic card.
This save my money, and my time.
we should do this at all travel city.
you'll become a rich man if you have such a shop
any thought?
