NFC stands for Near Field Communication, which is a wireless technology that enables two devices to exchange information when they are in close proximity (within 10 cm).
NFC is a speedy way of wireless data transfer without the need for an internet connection. It detects technology in close proximity and enables it to communicate.
However, the devices need to be compatible to connect. At least one of them has to be transmitting, and the other has to receive the signal.
There’s more – devices can be either passive or active.
Passive NFC devices are able to send information to other NFC devices without needing a power source. This includes tags and other small transmitters.
They can’t connect to other passive devices and don’t process any info sent from other sources. Usually, these are interactive signs on walls or advertisements.
On the other hand, active NFC devices can send and receive data and communicate with both active or passive devices. They are more sociable!
How Does NFC Work?
NFC is a short-range wireless technology. It’s just like Bluetooth, but it only works within a few centimeters of each other.
The good news is that you don’t need to pair your devices or share any passwords or keys. The bad news is that the range is limited to about 10 cm (4 inches), so if someone walked by and accidentally bumped into your phone, it would probably work!
NFC stands for Near Field Communication, and it’s a way for your smartphone to communicate with other devices without touching them directly. When you tap two NFC-enabled devices together, they transfer information back and forth using radio waves at 13.56 MHz.
NFC Pros And Cons
The most common uses of NFC are mobile payments and sharing contacts, photos or videos between two smartphones (or other NFC-enabled devices) by tapping them together.
NFC technology is a convenient way to pay and do other things with your smartphone. With it, you can scan a QR code or simply tap your phone against a terminal to pay for something.
NFC is convenient because it lets you control essential parts of your life easily. Your smartphone is always in your hand anyway – so why not use it to pay in the store, on the bus, and everywhere else! And with contactless credit cards using NFC tech, payments are much quicker.
The setup time is short enough to make it easy for you to adopt the tech. Just a few taps is all you need! For Android, you simply go to Settings->Share & Connect->NFC and that’s it – you’ve switched to NFC mode. (For iPhone users, the NFC setting is in Communication settings.)
It is more secure to pay using an NFC-enabled device because that way no one has physical access to your credit card info. And if your device is stolen, your PIN and password are still protected.
The versatility of NFC is limitless. It can be used for a wide range of purposes – from fun to more serious stuff like payments. And with more retailers accepting contactless payments every day (and even cashiers asking if
