The technology behind contactless payments includes Near Field Communication (NFC) and RFID (Radio Frequency Identification). These technologies enable devices, like smartphones or contactless payment cards, to communicate wirelessly with payment terminals. By simply tapping or waving the device near a compatible machine, consumers can complete transactions quickly and securely. Contactless payments enhance the customer experience by streamlining the checkout process, reducing wait times, and promoting hygiene, especially in a post-pandemic world where minimal contact is preferred.
