Registration is necessary depending on how much crypto you're looking to buy or sell. For amounts up to $900 USD, you'll have to input your cell phone number and first/last name. You will also need to type your first and last name on the ATM's screen. For amounts between $901 and $2995 USD, registration is required. The machine will ask you to put your state-issued ID up to the camera, and then to take a selfie in front of the camera. Once registered, you will not have to register again. CoinFlip also offers a $12,000 limit to customers who undergo the company's enhanced verification procedures. For more information, please call us at (773)-800-0106.
