NFC stands for Near-field communication, which is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm or less. NFC tags are passive data stores that can be read, and under some circumstances written to, by an NFC device. Here are some key points about NFC tags:
- NFC tags are smart little chips that allow you to snag digital information with your smartphone at short range.
- They are passive electronic tags that can be read by compatible hardware using radio waves.
- NFC tags are used for identification, authentication, and tracking.
- They can be embedded in a small tag to facilitate data transfer between nearby mobile phones, laptops, tablets, and other electronics.
- NFC tags are surprisingly versatile and tend to be useful in situations where you might want to transfer small amounts of data effortlessly.
- They come in various form factors, ranging from small stickers to credit card-like plastic cards.
- NFC tags can be used to automate tasks and for better communication between devices.
- NFC technology can be found in hotel key cards and NFC-equipped credit and debit cards for contactless payments.
- NFC tags can even turn your home into a smart home.
NFC tags are more secure than QR codes for many short-range applications. They can be used in a variety of creative ways, and their basic mode of operation is the same as that of an NFC-enabled smartphone acting as an NFC tag.
