What you need to know about NFC

NFC stands for Near Field Communication. It enables wireless and two-way communication between devices using interacting electromagnetic radio fields. Like Bluetooth technology, NFC only works within a short-range. The devices must be within 10 centimetres or 4 inches max to share bits of information. When the devices come close, they will be energized and will be prompted to transfer data.

NFC tags are small, self-adhesive labels that are attached to objects of any kinds. Each tag has an NFC microchip, small storage for memory, and an antenna. Just like many tagging systems, NFC tags don't have to be plugged into a power source. Notice that they don't contain a battery. So, how do they work? Through magnetic induction, the tags can draw power from away from the device that they made contact with.  

NFC tags are programmable using NFC tools and applications. You can write or program a specific task on an NFC tag. Aside from paying bills or receiving payments, people have also been using NFC tags to accomplish simple everyday activities such as setting alarms, connecting or disconnecting to Wi-Fi, unlock doors, and launching phone apps. Just remember that you have to use separate tags for each specific task. In retail, businesses write on their NFC tags to share information about their products, for promotions, for marketing campaigns, and many more.
