That’s all you need: One NFC tag for endless applications
An NFC tag is a small passive object, without a power source, that can interact with a mobile phone. It contains an NFC chip and an antenna. The chip has user memory that can be written to using a standardized data format and allows the phone to read the data, for example, opening a specific URL to a mobile experience in a web browser. NFC tags come in many different sizes and antenna shapes. The larger the antenna, the greater the range (usually up to 4 inches or 10 cm). We recommend using large antenna sizes if possible for a smooth user experience. If you want to reduce the range to very close for added security, choose a smaller model
