A Bitcoin ATM has landed at a Boston rail hub, allowing commuters to learn about the digital currency.

On Wednesday, the ATM was placed by Liberty Teller at Boston's bustling South Station, which sees thousands of commuters a day. It and an ATM in Albuquerque, N.M., are believed to be the first in the country.

Liberty Teller founder Kyle Powers tells WCVB-TV that the ATM gives people the chance to learn about the volatile currency, because after buying some, they can watch a company tutorial on its use.

Colleague Chris Yim says the money can be stored in a virtual wallet and used at an increasing number of online retailers in place of cash or credit cards.

Bitcoin is an open-source currency affiliated with no country or bank, which can be bought and sold anonymously.
