Mobile Payment Technologies

• Near Field Communication (NFC) enables contactless mobile payments by allowing devices to communicate when in close proximity (typically less than 4 inches)
  • Used by mobile wallets like Apple Pay, Google Pay, and Samsung Pay for tap-to-pay transactions at compatible point-of-sale (POS) terminals
• Quick Response (QR) codes are two-dimensional barcodes that can be scanned using a smartphone camera to initiate mobile payments
  • Commonly used in countries like China through payment apps like Alipay and WeChat Pay
  • Gaining traction in other markets as a low-cost, easily accessible mobile payment option
• Magnetic Secure Transmission (MST) is a technology used by Samsung Pay that emulates the magnetic stripe on traditional payment cards allowing it to work with most existing POS terminals
• Tokenization replaces sensitive payment data with a unique, randomly generated token to secure transactions and protect user information
• Biometric authentication uses unique biological characteristics like fingerprints or facial recognition to verify user identity for mobile payments adding an extra layer of security
• Bluetooth Low Energy (BLE) is a wireless technology that can be used for mobile payments, particularly in situations where NFC may not be available or practical (vending machines, parking meters)
• Sound waves can also be used for mobile payments by transmitting encrypted payment data through high-frequency audio signals inaudible to the human ear
• Invisible payments use a combination of technologies (NFC, QR codes, biometrics) to create a seamless, automated payment experience without the need for manual intervention (Amazon Go stores)
