Automated teller machines (ATMs) made banking convenient. Bitcoin ATMs have similar functionality. These are kiosks where people can buy or sell Bitcoin using real money. They work just like regular ATMs but have more security features such as fingerprint scanning and validation codes.
A Bitcoin ATM is not linked to a bank account but connects users to a bitcoin exchange through the Internet. Some machines, though, may require you to have a bank account before they let you transact.
