Round 30mm Anti Metal HF RFID Sticker, NFC Epoxy Tag For Data Transmission

NFC stands for Near Field Communication. Essentially, it's a way for your phone to interact with something in close proximity. It operates within a radius of about 4 cm and provides a wireless connection between your device and another. This allows for two-way communication, with both devices involved being able to send and receive information. This NFC connection does not rely on Wi-Fi, 3G, LTE or otherwise, and it doesn't cost anything to use
