All licensed Bitcoin ATMs in the United States are required to ask their customers for proof of identification thanks to Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations. Typically, Bitcoin ATM operators will ask for a government-issued identification to set up your account. While many Bitcoin ATMs may ask for proof of identification while using the ATM, others only require you to provide a government-issued identification when you register for an account. Once you have your account, you can exchange crypto for cash at a Bitcoin ATM using your phone and two-factor authentication via SMS or a mobile app. They require institutions subject to AML regulations to gather data on their customers, such as their identification, phone number, or other contact information.
