“Contactless payment technology” in retail enables consumers to make transactions without physical contact with payment terminals. Utilizing near-field communication (NFC) or RFID (Radio Frequency Identification) technology, customers can complete purchases by tapping a phone, card, or wearable device against a reader. This method improves transaction speed and convenience, reducing wait times at checkout. Contactless payments enhance customer experience by providing a seamless purchasing process while maintaining security through encrypted data transmission, thus increasingly being adopted in modern retail environments.
