These tags don’t have batteries in them, but they do have a bit of memory. When you place your phone’s NFC reader near them, the NFC reader provides power to the tag, and can read the data from the tag. The tags are programmable, so you can write whatever data you want into the tag from your phone.

NFC is a lot like RFID, only it's a more up-close-and-personal type of wireless. Whereas RFID can be used from a distance, NFC readers work at a maximum range of about 4 inches (10 centimeters). NFC readers aren't suitable for RFID-style inventory tracking; their range is too short. So NFC tags will appear in a flood of products and promotional items where bits of digitized information might come in handy.
