Contactless payment refers to a secure and convenient method of making transactions without the need for physical contact between a payment device, such as a credit card or smartphone, and a payment terminal. This technology uses near-field communication (NFC) or radio frequency identification (RFID) to transmit payment information wirelessly, allowing for quick and effortless payments with just a tap or wave of the payment device. Contactless payment is becoming increasingly popular due to its speed, ease of use, and enhanced security features, making it a preferred choice for many consumers and businesses alike.
