What is NFC in Smartphones and What are the Functions of NFC?
Are you currently using a smartphone that has NFC available? Maybe you don’t know what NFC is. Currently, we have found many NFC features in several cellphones, especially in middle to high-end phones.
You can use NFC to make digital payments via contactless (contactless) such as Pay or Apple Pay. So the question is, how does NFC work?
What is NFC?
NFC stands for (Near Field Communication) or can be interpreted as a near field communication tool. This feature can work if both devices are compatible or the NFC feature is available. Where one device acts as transmitter and another to catch the signal.
In addition to the use of NFC to make payments electronically, another use of NFC is to be able to easily connect smartphones with other devices. For example, a digital camera that is NFC compatible. NFC can also be used for tickets when using public transportation or want to visit venue event.
How NFC and NFC Functions Work on HP
If you look at how NFC works, it’s almost similar to Bluetooth or WiFi, which relies on radio waves to share information. NFC using technology radio-frequency identification (RFID). This technology relies on induction from electromagnetics to transmit information.
NFC can also be used to induce any electric current available in passive components, only sending data. For example, when making payments on an electric card.
To connect with passive components, they require no power at all. Because it uses the electromagnetic generated from an active NFC device. This is the difference between NFC and Bluetooth.
Mode Used NFC Technology
Basically, NFC is available in three modes with different operating methods. But the mode that is widely used there is peer-to-peer.
With this mode, both NFC-enabled cellphones can exchange various information with each other. Besides that, you can also use this mode to send files, data just by pasting devices with one another.
Is Bluetooth Still Important After There’s NFC?
Bluetooth is still not replaced today, because many are still unfamiliar with NFC technology. In addition, currently the average cell phone does not have the NFC feature.
However, there are several advantages that NFC does not necessarily have Bluetooth. One of them is in the power consumption section.
NFC is considered more power efficient than Bluetooth, but the transfer speed is still inferior to Bluetooth.
The data transfer speed of NFC reaches 424 kilobits/second. While the old version of Bluetooth 2.1 can reach 2.1 Mbit / sec.
In addition, NFC to be connected requires close range compared to bluetooth. The NFC distance to connect should not be more than 10 cm. While bluetooth can be reached within 10 meters.
But another advantage of NFC is the connection speed. NFC only takes less than 10 seconds to connect the two devices.
But unfortunately the adoption of NFC is currently a bit slow. Because not all phones already use the NFC feature. Only mid-to-high-end phones have just tasted this feature, while lower-middle-class phones are only available.
