NFC

What Is NFC?

NFC is an abbreviation for “near field communication”. As can be understood by its explanation, NFC enables wireless communication technologies. To explain better, when the phone and the payment terminal are close to each other, it allows them to communicate with each other wirelessly or without contact. The goal of NFC is to enable communication safely and efficiently. NFC only works at close range.
Data transfer becomes possible between NFC compatible phones, cards, card readers and other terminals. Briefly, It is a short-range wireless communication technology that uses electromagnetic induction to enable two devices to connect, exchange information or activate various functions.
Authentication and connection takes place completely automatically, without the need to enter any PIN or password. Data can be passed from one device to another by simply touching it or at a very close distance.

What Does NFC Do On My Phone?

NFC is a feature found in smartphones and not very well known. Establishing a two-way connection between devices, this feature allows two devices to send and receive simple command information. These features aim to communicate wirelessly between devices.
The possibilities provided by the NFC feature are not limited to this. It is possible to see transaction settings with NFC in the mobile banking application where you have a credit or debit card. You can also make contactless payments without using your card when the POS device at the point of payment has NFC support.

Should NFC Be On Or Off?

NFC needs to be turned on when you want to use it. When you do not plan to use NFC, it is recommended to turn it off to save battery life and avoid security risks. While NFC seems like a secure system, some security experts recommend turning it off in public as it can be vulnerable to hackers.

How Does NFC Work?

NFC technology takes advantage of a wireless communication technique that uses different physical principles than radio, based on RFID standards such as ISO-IEC 14443 and ISO-IEC 15963. Most radios transmit data via radio wave propagation, while NFC transmits data via magnetic field induction at 13.56 MHz, which corresponds to a wavelength of 22 meters. The main advantage of transmitting data by induction rather than radio waves is that the field fades much faster than radio waves. Thus, the ability to listen to the conversations between the devices from the outside is significantly prevented.
Another considerable feature of NFC in terms of its working principle is cryptographic credit card transactions used for contactless payments. Conventional RFID and credit card usage applications are done via a passive tag or active card reader as a one-way interaction. Public key encryption allows the credit card to generate a new authentication code for each transaction, without revealing the three-digit security code. This way, even if a hacker interrogates your card on a subway, they won’t be able to access the original card details.

Is NFC Safe On Phone?

In order to transfer data with NFC, devices must be very close to each other, so it is generally accepted as a secure technology. You can choose to be even more careful against possible attacks by keeping this feature turned off when you are not using it. Nevertheless, it will be enough to keep your phone with you. Since you will be asked for confirmation when transferring information with NFC, it is not possible to do any data theft through this technology.

Does NFC Work Without the Internet?

NFC technology works when two devices are close to each other. No internet connection would be required.

Why Is NFC Necessary?

One of the biggest reasons why NFC is considered necessary is the convenience it provides. You can only pay by phone without having your credit card with you. Since the payment method is contactless, you can save time by making payments with NFC. For those who still prefer cards, NFC-enabled cards provide the same functionality in a convenient and familiar package.
Another important feature is that it is safe. As mentioned above, since NFC operates at close range, it becomes very difficult for hackers to attack, unlike wireless internet technology.
Besides, NFC payments help speed up checkout lines, enhancing customer success with your business.

How Do You Pay With NFC?

To pay with NFC, you need to add a mobile wallet app to your internet-connected device. Google Pay, Apple Pay, Samsung Pay and PayPal are some of the popular mobile wallet apps. After connecting your mobile wallet to an existing credit card, debit card or bank account and completing the setup, you can pay via NFC anywhere with an NFC terminal.
