Contactless services refer to transactions or interactions that do not require physical contact between individuals or devices. This technology often utilizes NFC (Near Field Communication) or QR codes to facilitate payments, check-ins, or information sharing. Users can complete these actions by simply tapping their smartphones or scanning codes, enhancing convenience and safety. These services have gained popularity, especially during the COVID-19 pandemic, as they minimize the risk of virus transmission. Many businesses, including restaurants and retail stores, have adopted contactless payment systems to streamline operations and improve customer experience.
