We all know very well that with the arrival of services like Android Pay or Samsung Pay, NFC technologies have become very common. As nowadays, most high and mid range devices incorporate NFC technology. With NFC technology now becoming a staple of the smartphone world, there isn’t a place for reviewers to also lower a device’s score if it doesn’t offer this technology.
What is NFC and how do you use it on your Android?
With the arrival of services like Android Pay or Samsung Pay, NFC technologies have become very common. As nowadays, most high and mid range devices incorporate NFC technology. With NFC technology now becoming a staple of the smartphone world, there isn’t a place for reviewers to also lower a device’s score if it doesn’t offer this technology.
What is NFC?
NFC stands for Near Field Communication, as the name itself suggests, simply allowing two devices to communicate over short distances. To do this, you need a transmitter and a receiver, while NFC-enabled devices are divided into active and passive.
In the first group, we can find NFC tags and other small transmitters, which can send information to other devices without needing their own power supply. However, they do not process information sent from other sources and cannot connect to other passive components.
As active devices, we can find devices capable of sending and receiving data; They can communicate with each other and with passive components like the ones we mentioned above. Basically, smartphones are the most popular active NFC devices, with payment compatible with services like Android Pay and others.
How NFC Technology Works
Like Bluetooth, WiFi, and all kinds of wireless signals, NFC technology works on the principle of sending information over radio waves. NFC technologies are inspired by RFID (radio frequency identification) communications.
To help you understand better, here is an example, when you disconnect the home alarm with the keychain or see those alarms attached to clothes in shopping malls, then you are using technology applications RFID.
Although it is a wireless communication protocol, there is a fundamental difference between NFC, Bluetooth and WiFi. As nowadays, the need for a power supply has gradually disappeared, because it is enough that the electromagnetic field produced by an active NFC component allows a passive component to send data.
But wait, as if you think wireless charging is done using NFC technology then you are wrong because it is a protocol called QI which is used to wirelessly charge any device. . The frequency of data transmission between NFC devices is 13.56 MHz, with speeds ranging from 106 to 424 kilobits per second, which is fast enough for most data transfers made from mobile devices.
How to activate and use NFC on an Android device?
In most current smartphones, activating NFC technology is as easy as showing the notification screen. By simply clicking on the pre-built default icon, you can simply enable the NFC function on an Android device. Here is the example of the image we mentioned below: –
With almost all security, enabling NFC technology in this way, the Android Beam will be activated automatically. This function simply allows two Android devices to share data, and the process is as follows: –
- We need two NFC and Android Beam compatible devices.
- Open the content we want to share in one of them.
- Then we need to put the two devices glued to the back.
- Now we will receive an audio and vibration confirmation once they connect.
- The receiver screen size will be reduced and the “Touch to Send” option will appear at the top of the screen.
- Simply touch the receiver screen to begin the process.
- Once you are done, you will receive a confirmation sound.
- At the end of the process, you will receive another audio confirmation or the app that manages it will open the sent content.
Some of the content that can be shared by NFC technology includes applications, URLs for accessing web pages, YouTube videos, contacts automatically saved in the recipient’s phonebook, and photos.
Pay with your smartphone using NFC
The most well-known applications of the NFC protocol are mobile payments. Currently, different services cover this aspect, with Google Pay and Samsung Pay as the most popular in the Android world.
Before using any of these payment platforms, you must first register with one of them. It should also be remembered that Samsung Pay is only compatible with Samsung smartphones, while Google Pay works on all Android devices running Android 4.4. higher.
