A bitcoin ATM is an internet machine that allows a person to exchange bitcoins and cash. Some Bitcoin ATMs offer bi-directional functions .. in other words you can purchase or redeem Bitcoin. In some cases, Bitcoin ATM providers require users to have an existing account in order to transact on the machine.
Bitcoin machines are not ATMs in the traditional sense. Bitcoin kiosks are machines which are connected to the Internet, allowing the insertion of cash in exchange for bitcoins given as a paper receipt or by moving money to a public key on the blockchain. They look like traditional ATMs, but Bitcoin kiosks do not connect to a bank account.
