This universal way of storing NFC information means that almost any NFC enabled device will be able to read and understand the data and what type of data it is. The data is usually stored in a particular way called NDEF (NFC data exchange format) encoding. For example, you may choose to encode a URL (web address), a telephone number or simply a small ID number. There's a wide variety of data types you can encode onto an NFC tag. While the form of the product will vary, inside there will be the same basic NFC tag with a chip, antenna and something to keep it together.Īdding data to an NFC tag is called encoding. Other NFC items such as wristbands, keyfobs or even drinks mats we refer to as NFC products. Seritag refer to NFC Tags in terms of NFC stickers, labels, inlays or discs. If the tag is a sticker, it will have adhesive on one side to allow it to be attached. The substrate holds it together and would typically be a thin sheet of plastic. The antenna is a coil or loop of wire which, in the case of a sticker, will be an etching a fraction of a millimeter thick. The NFC chip is a tiny microchip which contains a small amount of memory and the technology to allow it to communicate. NFC tags, for example stickers, contain small microchips with little antennas which can store a small amount of information for transfer to another NFC device, such as a mobile phone.Īn NFC Tag itself consists of three basic components: an NFC chip, an antenna and something to keep it together. NFC (near field communication) is a wireless technology which allows for the transfer of data such as text or numbers between two NFC enabled devices.
