NFC, or Near Field Communication, is a technology that allows contactless data transfer between devices over short distances. It has many applications, including mobile payments, hotel room keys, and Disney's MagicBands. While not widely used currently, NFC adoption is growing and several services are taking advantage of it. NFC will streamline operations for businesses in hospitality and other industries by speeding up payments and allowing for more customer interaction. It may eventually replace credit cards for mobile payments and improve marketing through more personalized experiences. Overall, NFC will enhance the quality and speed of service across various industries like hospitality.
