NOWPayments – 2024 Before using Google Pay to buy Bitcoin or other cryptocurrencies on CEX.IO’s mobile app and/or Wallet app, we recommend setting up Google Pay on your device first to ensure it is recognized by our services as a viable form of payment. While CEX.IO’s mobile products and services are designed to integrate seamlessly with Google Pay, you must have already set up Google Pay so that the CEX.IO mobile and/or Wallet app knows to suggest Google Pay as a form of payment. To accept BTC or another cryptocurrency, a merchant needs to connect special payment services or integrate technical solutions that generate a wallet address to which customers can transfer funds. Bitcoin payment method is quite easy and fast. A customer opens their crypto wallet, scans the QR code of the payment account on the merchant's website, and confirms the action with a pin code or other means. After funds are credited to the specified account, the Bitcoin network recognises and confirms the transaction. Thanks to blockchain technology, each transaction conducted is stored in a single ledger. Everyone has access to information about all transactions, but none of the parties can change or falsify the transaction record.
