NFC Full Form Is Near field communication. It refers to short-distance communication between compatible electronic devices where one device acts as a transmitting device and the other as a receiving device. These devices should be within a range of 10 cm. The underlying layers of NFC technology include the ISO, ETSI, and ECMA standards.
NFC is a short-range high-frequency wireless communication technology developed to exchange data between devices. It is an upgrade to the existing Proximity Card standard. It allows you to share content between digital devices, pay bills wirelessly, or use a cell phone as an electronic travel ticket for public transportation using a contactless infrastructure.
एनएफसी का फुल फॉर्म इज नियर फील्ड कम्युनिकेशन। यह संगत इलेक्ट्रॉनिक उपकरणों के बीच कम दूरी के संचार को संदर्भित करता है जहां एक उपकरण एक संचारण उपकरण के रूप में कार्य करता है और दूसरा एक प्राप्त करने वाले उपकरण के रूप में। ये उपकरण 10 सेमी की सीमा के भीतर होने चाहिए। एनएफसी प्रौद्योगिकी की अंतर्निहित परतों में आईएसओ, ईटीएसआई और ईसीएमए मानक शामिल हैं।
एनएफसी एक छोटी दूरी की उच्च आवृत्ति वाली वायरलेस संचार तकनीक है जिसे उपकरणों के बीच डेटा का आदान-प्रदान करने के लिए विकसित किया गया है। यह मौजूदा निकटता कार्ड मानक का अपग्रेड है। यह आपको डिजिटल उपकरणों के बीच सामग्री साझा करने, वायरलेस तरीके से बिलों का भुगतान करने, या संपर्क रहित बुनियादी ढांचे का उपयोग करके सार्वजनिक परिवहन के लिए इलेक्ट्रॉनिक यात्रा टिकट के रूप में सेल फोन का उपयोग करने की अनुमति देता है।

NFC applications can be divided into the following four basic categories:
- Touch and Go: In this method, the user has to bring the device that stores the ticket or access code closer to the reader.
- Touch & Confirm: This happens in mobile payments, where the user has to confirm the payment by entering a password or simply by accepting the transaction.
- Connect and Touch: In this application, two NFC-enabled devices are connected to allow peer-to-peer data transfer, such as downloading music, sharing images, and more.
- Touch and explore: NFC devices can do more than one thing. The user can find out the capabilities of the device to find out the available services and functions.
How does NFC work?
It is a standard for wireless data transistors that send information over radio waves and is based on older RFID (radio-frequency identification) ideas, which use electromagnetic induction to transmit information. Its power consumption is lower than Bluetooth, which makes it perfect for passive devices such as inductors, resistors, capacitors, etc. as it can induce electric currents in passive components and send data. This means that the passive device does not need its power supply as it can be powered by the electromagnetic field of the active NFC component.
NFC Full Form: Types of NFC
There are mainly two types of NFC.
Active NFC device
Active NFC devices are those devices that can send and receive data and with this, they can also communicate with each other whether they are active devices or passive devices.
NFC devices require a power source to work. They have the ability to process information. For example, a smartphone is the most common form of an active NFC device. And Apart from this, public transport card readers and touch payment terminals are also excellent examples of this technology.
Passive NFC device
Passive NFC devices are called devices that can only send information to other NFC devices. So They do not require any external power source for their operation. And Apart from this, they also do not have the ability to process information.
They also cannot connect to other passive components. For example, they are more commonly used in tags and other small transmitters used as conversational signs on walls or in advertisements.
Advantages of NFC
Convenience: Most consumers want convenience while paying. In today’s society, people like spontaneity more. NFC is a much better option in this matter. This helps your mobile device to merge with the wallet. NFC plays an important role in this process as payment can be done with just a simple touch. With this, you can imagine how long lines of the grocery stores can be ended very easily.
Versatility: NFC can be adapted to all situations. You speak about any situation whether it is for transit passes using bank cards, movie passes, reward systems, or keys. Ideally, NFC can be used in a broad range of industries.
Better Customer Service: With the advent of NFC, many tasks are automated, which accelerates Customer service. This gives companies more time so that they can provide even better service to their customers.
Real-Time Updates: Since real-time data can be fetched from many places with the help of NFC, many tasks can be easily maintained. It doesn’t even require many people.
NFC Full Form: Disadvantages of NFC
Short distance: NFC only works when two devices are very close, which can prove to be a headache for people at comparatively long distances as they can connect the devices only when they are close to each other.
Low Speed: The data transfer rate is still very low, from 100kb/s to 424kb/s, making it difficult and time-consuming to transfer large data.
Expensive: It is difficult for the small business sector to adopt NFC technology because the cost of installation and maintenance can reduce substantial profits.
Low profit: Many customers looking for payment via the NFC system turn to large companies, small companies for whom NFC is costly losing their customers.
Security issues: Even after proven security comparisons with credit cards; NFC systems still face security threats, as there are still major technology development frauds. Mobile hacking puts the entire data and NFC system in question. The vulnerability serves as an ongoing challenge in this technology in terms of security issues towards personal data.
Power Consumption: It is observed that NFC compatible devices have a slightly higher power consumption rate than others.
FAQ’ S On NFC Full Form
What is NFC used for?
Near Field Communication (NFC) allows wireless communication between two electronic devices that are close to each other. Officially, NFC can support distances of up to 1.5 inches, but in practice, it can be up to four inches.
How to use NFC on the phone?
NFC is a method of wireless data transfer that allows smartphones, laptops, tablets, and other devices to share data in close proximity. Technology powers contactless payments through mobile wallets such as Apple Pay, Google Pay, as well as contactless cards.

NFC Full Form: Is NFC useful in India?
During these difficult times of maintaining social distancing and avoiding contact; NFC payments, a contactless payment facility, have emerged as one of the most viable payment options digitally. People in India can also use this facility by using Google Pay or GPay.
What is NFC vs Bluetooth?
NFC is best used over short distances to securely send small amounts of data; so it is most commonly used for access control and payments. On the other hand; Bluetooth, while not as secure, opens up a larger connection range and is often used on wireless devices such as headphones and audio speakers.
Can I set up NFC on my phone?
Download and install the “NFC Easy Connect” app on your Android smartphone. And Search for “NFC Easy Connect” on the Google Play™ Store. So The app may not be downloadable in some countries/regions. And Install the “NFC Easy Connect” app on the smartphone by following the on-screen instructions.
