We hear a lot about the NFC feature and that it is present in some smart phones, and we also heard about applications such as Apple Pay, Android Pay and Samsung Pay, and this feature connects with electronic payment devices only by bringing the mobile phone closer, but we still Not all of us know enough information about what nfc is, so let's enter this article into the world of modern technology and get to know this technology together.
The idea of nfc technology came from RFID technology or what is known as “Radio-Frequency Identification”, a technology that was and still is used in large retail stores, as it enables the seller to track goods through the physical term known as electromagnetic induction or “electromagnetic induction”. To transfer information over small distances, which is what happens simply for the seller to pass the tape that carries the data on a specific device, and then the information is transmitted to his computer. NFC technology is a technology completely similar to this technology and also inspired by it, but it is specific to smart phones.
This technology was defined by a group called the “NFC Forum” that includes Nokia, Sony and Philips.
It can be considered as an upgraded version of the QR Codes
As a simple definition, NFC is: one of the means of communication between devices at a close distance, such as infrared technology, but it is more and more sophisticated. Many devices support NFC, such as Android devices (Nexus 4 ; Galaxy Nexus ; Samsung galaxy s3 & s4 ; HTC ONE X) and some Windows Phone and BlackBerry devices, but so far no Apple device supports this technology.
NFC technology sends data through radio waves. It is similar to Wi-Fi and Bluetooth technologies, but it is not like those protocols where NFC technology can be used to induce electric current through passive components in addition to sending data. And it's much faster than Bluetooth.
Some problems with nfc technology:
There are some security problems that accompany this technology, but they are still governed. For example, but not limited to, if someone close to you owns a reader of the technology, he can It reads the contents of your device if you have the NFC feature activated, but it is not expected in any case that there is a person with a card reader standing a few inches near you, but it remains a matter of concern.
And I have found some attempts to make some applications that can circumvent and can access your phone and withdraw your credit data
But there are in the Google Play Store and the Apple Store, especially the latter, that has a high ability to protect your phone from all such applications, but in any case you cannot trust any of them 100%
The greatest danger caused by NFC technology is that it makes your phone more valuable, as you put all your credit and payment data inside it, which makes you more vulnerable to the risk of phone theft, and it is no longer just a phone, but rather a wallet for all your data and important information, and a wallet for money as well.
