What Exactly Is NFC? ‘Near Field Communication’ Technology



In this article, we will look at what exactly is NFC, the technology that underlies contactless payments.

We will also look at its uses in short-range transmission and energy.

We’ll also discuss how this technology can help with security. Whether you’re an entrepreneur, a student, or a healthcare worker, NFC can help you make life easier.

You’ll learn how to use NFC to stay on top of your business and get paid quickly and easily.


Contactless Payments

Many banks have embraced contactless payments with NFC technology to increase their customer service.

Offering contactless options for payment also promotes an improved customer experience and helps banks differentiate themselves from their competitors.

Moreover, the increased use of contactless smartcards may also be due to the emergence of new, upmarket contactless smartcards, such as metal cards.

These cards may target VIP clients. Contactless payments with NFC are gaining popularity amongst consumers in the U.S.

To take advantage of contactless payments with NFC, a consumer must place their contactless chip card within two inches of the terminal’s Contactless Symbol.

In addition, Visa offers a Zero Liability Policy to protect payment information.

Contactless payments with NFC help businesses reduce their capital, operational, and environmental costs while increasing employee productivity.

To start accepting contactless payments, businesses should look for an NFC-compliant retailer.

Consumers should be aware of the security risks associated with mobile payment apps, and providers should provide instructions for minimizing these risks.

Additionally, providers must continue to update their payment apps, and they should be aware of any ongoing security issues. However, consumer behavior is also crucial.

To protect the privacy of their bank data, consumers should always use a passcode on their mobile devices.

If they lose their mobile device, they should immediately take the necessary steps to prevent any unauthorized use.

While frictionless payments are a faster way to pay, they can also reduce the number of time employees spend serving customers.

Since most contactless transactions are done without receipt printing, they reduce the number of abandoned sales.

The average transaction value is higher than ever, resulting in happier customers.

Contactless payments with NFC can also make the payment process more efficient, with the receipt being printed only when the transaction value is higher.

That means less wait time for customers and faster checkouts.

Short-Range Transmission

Near Field Communication (NFC) is a short-range wireless communication standard that is rapidly being adopted in both professional and consumer electronics.

Its main purpose is to enable quick and easy wireless connectivity.

It has already seen extensive use in contactless payments, virtual event tickets, access control, and information sharing between smartphones.

In the AV industry, NFC integration is becoming increasingly common in audiovisual devices.

Its low power consumption and wide range of applications are making NFC a highly desirable technology for AV applications.

The NFC standard specifies three operating modes for a flexible gateway system.

Active mode requires both the initiator and target device to actively generate a radio frequency field and a power supply device.

This mode achieves very high connection rates. The NFC standard specifies that a gateway device should be able to operate in all three modes.

For example, an NFC target device may not be able to detect a contactless card, but it can detect an NFC initiator.

The two-way persistent connection is an important feature of NFC. The PHDC application protocol is an example of this strategy.

This application protocol makes frequent polling of the tag, allowing both devices to maintain contact and communicate.

The NFC standard allows NFC devices to communicate with each other while inactive devices are not allowed.

The Android platform also supports the ISO-DEP protocol, which abstracts Types 4A and 4B. In addition, NFC-F supports the PICC protocol, a FeLiCa stack protocol.

In addition to speed, NFC has several other features to consider.

For instance, if there is interference from nearby wireless devices, a 900-MHz signal will travel further than a 5-GHz signal.

In addition, a 900-MHz signal is likely to travel longer than a 60-GHz signal.

While ultra-high-speed data can be transmitted at high speeds, it requires multiple transmitters and receivers.

Energy Source

An NFC-based data logger consists of an antenna to receive the interrogation signal, a battery, or an additional harvesting source.

A microcontroller or an integrated circuit can also communicate with the NFC-enabled device.

An energy-harvesting NFC circuit is responsible for rectifying the RF signal and extracting energy from it.

In passive operation mode, an NFC-enabled sensor may operate in a semi-passive or passive mode, with an internal battery.

Implantable medical devices (IMDs) can include NFC sensors for monitoring and reconfiguration.

Since small implants have a low coupling coefficient, the range of energy harvesting is relatively limited.

However, the use of a relay coil on the body surface can increase the energy harvesting range.

An NFC-based tag can provide a variety of health-related data, including the pH level of the patient.

Ultimately, a noninvasive NFC pH sensing system could be used to detect the early stages of infection.



There are several ways to secure NFC technology.

In addition to encrypting data, NFC devices also use a secure channel to avoid a common attack known as the “man in the middle.”

In such an attack, a third party acts as a relay to intercept and modify information transmitted between the sending and receiving devices.

However, to perform a successful attack, the attacker must not reveal himself or herself.

NFC uses an active-passive communication mode to minimize the risk of a man-in-the-middle attack and allows users to detect the intrusion of an unwanted third party.

An application can be tested by modifying the pairing logic. For example, if a device uses Bluetooth, it should modify its logic for pairing.

To ensure security, NFC applications must adhere to the NDEF specification. Similarly, special characters can trigger security issues.

By modifying the pairing logic and avoiding special characters, applications can be tested for security vulnerabilities.

The GNFCVulFinder can be used on any platform: Android, Windows Phone, and BlackBerry.

It is an easy-to-use tool that is compatible with multiple mobile platforms and can be used in real-world environments.

The emergence of NFC technology is a boon for marketers, but it also presents a problem. The increasing popularity of NFC devices is a great opportunity for cyber-criminals.

As a result, a greater number of 0-day vulnerabilities will be discovered and new exploit kits will be offered on the black market.

Furthermore, an NFC flaw in one of these devices can cause severe problems in various sectors. That’s why it is so critical to secure NFC technology.



There’s no doubt that NFC is getting more popular. But how do you know if NFC is right for your product?

The good news is that its price is drastically lower than it was ten years ago. In fact, some companies have already reduced the price of NFC tags to less than 10 cents.

Listed below are a few examples. Each NFC tag has a different capacity, and the cost will vary accordingly.

First, NFC is cheap. It costs less than $50 to implement, and the processing time is just 0.98 seconds.

In addition, it’s relatively easy to program and works with current hardware.

However, because the hardware is more expensive, NFC’s price has not been competitive enough to penetrate low-cost FMCG goods.

The prices need to be reduced dramatically if NFC is to become a viable option for everyday goods.

Another important issue is cost. While an NFC tag’s cost is higher than a barcode, the cost of the microchip itself is much lower.

The cost of the silicon microchip is determined by the area of the chip, which could cost as little as five cents in large quantities.

Then there’s the copper coil, which adds another $10 to the total cost of the NFC tag. And last, but not least, there’s the label.

With so many components, it’s unlikely that the NFC tag will be cheaper than a barcode.

Another important factor in deciding if NFC is right for you is how much you want to spend on the hardware.

It’s important to remember that NFC payments will likely account for more than $130 billion dollars in consumer retail purchases globally in five years.

However, the initial investment might seem to be a high cost for an NFC terminal, but it’s an investment that will pay off in the long run.

If you’re planning on opening multiple locations, you’ll have to purchase the necessary hardware for each location.

However, future-proof hardware is a smart investment in your company.


Which Devices Are Equipped With NFC?

Every day, more and more NFC-enabled devices are being introduced to the market.

NFC World maintains a list of NFC-enabled phones that is, for the most part, up to date so that users can track what devices are utilizing the NFC technology.

NFC is built into various Android devices, and it’s been included in every generation of iPhone since the iPhone 6.

Questions People Also ask:





What is an NFC tag?

NFC tags are small integrated circuits that contain a copper coil and a certain amount of storage space.

This tag does not have its power supply, so the only way data can be read from or written to it is when another NFC device is brought into proximity.

The proximity of the NFC device causes the tag to generate power, which enables it to send and receive data.


What exactly is an NFC reader, though?

An NFC reader can be any powered device that already possesses its own NFC coil, such as a smartphone or tablet computer.

The battery inside the reader device is used to produce an electromagnetic field, which in turn provides power to any tags that are brought close to it.

Another typical example of a reader is a payment terminal, which validates a debit or credit card by employing near-field communication (NFC).


Does Apple’s iPhone support NFC? What about Android devices that support NFC?

NFC hardware is included in every iPhone model released after the iPhone 5S in 2014 (the 6 and later models).

When it comes to Android, the majority of devices in the mid-range and premium price points support NFC.

To determine whether or not the feature is available, you can check the manufacturer’s website or read reviews written by third parties.
