Contactless payment is a secure and convenient method of completing transactions without the need for physical contact between a payment card or mobile device and a point-of-sale terminal. It utilizes near-field communication (NFC) technology to enable quick and wireless communication between the payment device and the terminal. Users simply need to tap their contactless-enabled cards, smartphones, or wearable devices near the designated reader to make a payment. Widely adopted for their speed and ease of use, contactless payments have become increasingly popular in various industries, including retail, hospitality, and public transportation. This technology enhances transaction efficiency and aligns with the growing preference for seamless and hygienic payment experiences.
