QR Code Payments
QR Code Payments is a digital payment method that uses Quick Response (QR) codes to facilitate transactions between merchants and customers. It involves scanning a QR code displayed by a merchant to initiate a payment, which is then processed through a mobile app or digital wallet. This technology enables contactless, fast, and secure payments, commonly used in retail, food services, and peer-to-peer transfers.
Developers should learn QR Code Payments to build or integrate payment systems in apps, e-commerce platforms, and point-of-sale solutions, especially for markets where mobile payments are prevalent like Asia. It's useful for reducing transaction friction, enhancing user experience in cashless environments, and complying with digital payment trends. Specific use cases include in-store purchases, bill payments, and event ticketing.
