QR code payment is a popular and convenient method of making digital transactions using Quick Response (QR) codes. With QR code payments, users can make payments by scanning QR codes displayed on a merchant's device or at a point of sale. The QR code contains payment information and is encrypted to ensure secure and fast transactions. Users can utilize their mobile devices to scan the QR code and authorize the payment using their preferred payment method, such as credit cards, digital wallets, or cryptocurrencies. QR code payments are widely used in various applications, including retail stores, restaurants, public transportation, and online shopping platforms.
