Near Field Communication (NFC) technology enables data transfer between devices in close proximity, utilizing NFC tags—stickers or wristbands with microchips that store data and can be read within ten centimeters. These tags are powered by the device reading them and facilitate quick data exchanges without manual pairing, useful for transferring app URLs or encrypted information. The article provides a comprehensive guide on using NFC tags with React Native, including configuring NFC for both Android and iOS platforms, and demonstrates how to read and write data to these tags using the react-native-nfc-manager library. It outlines the process of setting up a React Native project, configuring the necessary permissions, and using specific methods to check device compatibility, read, and write NFC tags, thus allowing developers to implement NFC functionality in their applications effectively. The article also highlights the practical applications of NFC technology in everyday scenarios, such as contactless payments and event check-ins, and encourages developers to build upon the provided tutorial to enhance their own projects.
