The people behind the machines say the devices convert cash into Bitcoins, a digital currency that requires no paper money and no banks. The electronic money can be used to make purchases on-line and at places such as Downtown Johnny Brown's that accept Bitcoins.
"You have the power to send money anywhere in the world to any person connected to the internet nearly instantly with virtually no fees and without third party interference," said Steven Michaels, C.E.O of Bitcoin Merchants.com, the company installing the machines.
Bitcoins have been around for five years and have been controversial since being designed by a Japanese businessman.
Concerns are many because this currency is not regulated.
People are assigned account numbers, which become virtual wallets. Since everything is electronic, people can tap into these accounts and steal the "money." And once the Bitcoins are spent, there's no way of getting them back.
Governments also worry Bitcoins can be used for illegal purposes.
