A Bitcoin ATM (automated teller machine) is a kiosk where users can buy Bitcoin, and sometimes even other cryptocurrencies, directly and automatically. They can convert their fiat currency into Bitcoin by inserting cash directly into the Bitcoin ATM or using their cards.
Unlike a traditional ATM that dispenses physical cash into the hands of the user, Bitcoin ATMs can be used to receive BTC or other cryptos in users' digital wallets or be transferred to others' wallets too. As a result, Bitcoin ATMs can also be used to complete crypto payments by transferring the purchased BTC into a crypto wallet of their choice.
Bitcoin ATMs are kiosks connected to the Bitcoin network and could also support other blockchain networks. Buyers can scan a QR code containing information about their wallet address or the wallet address they wish to make BTC payments. The machine then converts the deposited or swiped cash into BTC and transfers them into the wallet.
