What are NFC Tags?

NFC tags are tiny, unpowered chips that can store small amounts of information. When a compatible device, like a smartphone, gets close to an NFC tag, it can read the information stored on it without needing to touch. NFC tags work differently with every phone, while most modern phones have NFC compatability, it is always smart to check your device.
