NFC or near field communication is a wireless technology that enables the transfer of data such as text or numbers between two NFC-enabled devices. NFC tags and NFC business cards contain tiny microchips with little antennas. It can store a certain amount of information that can be transferred to another device.
NFC is not a revolutionary technology. It is a standard for wireless radio communications, similar to Bluetooth or WiFi. NFC is the closest relative in wireless communications is RFID or radio frequency identification. Retailers and parcel shipping companies typically use RFID to keep track of inventory supplies and shipments.
The Different Components of an NFC Tag
An NFC tag consists of different components, which are the following: an NFC chip, an antenna, and something to keep it together. An NFC chip is a tiny microchip that contains a small amount of memory and the technology to allow it to communicate and transfer information to another device. Meanwhile, an antenna is a coil or loop of wire which will be etching a fraction of a millimeter thick in the case of a sticker.
What information can you store?
Adding data to custom NFC tags is called encoding. A wide variety of data types can be encoded on an NFC tag. One example is encoding a URL, web address, telephone number, or a small ID number. The data is typically stored in a particular way called the NDEF or NFC data exchange format encoding. This universal method of storing NFC information means that almost any NFC-enabled device can read and understand the data and its type.
The amount of data that can be stored on an NFC tag varies depending on the type of NFC chip used. Different tags contain different chips, and each chip in an NFC has a specific memory capacity.
