Contactless payment systems allow consumers to make transactions without physically swiping a card or inserting it into a terminal. Instead, users can simply tap their credit cards, debit cards, or mobile devices equipped with near-field communication (NFC) technology on a compatible payment terminal. This method speeds up the checkout process and enhances convenience. These systems are widely used in various settings, including retail stores, restaurants, and public transportation. They provide a secure way to pay, as the transaction data is encrypted and transmitted wirelessly. As a result, contactless payments are becoming increasingly popular among consumers and businesses alike.
