What is NFC (Near Field Communication)?
Nowadays, NFC is available in every smartphone so, Everyone has a need to know, What is NFC and How does it work in mobile phone?
NFC is one of the more recent wireless connectivity technologies emerging in the consumer electronics market. It has huge potential in the professional AV (Audio Visual) sector also with a great invention. The full form of NFC - which stands for Near Field Communication. It is a standards-based, short-range wireless connectivity technology being increasingly and likely adopted in both consumer and professional electronics and particularly for integrating mobile devices as a means of exchanging digital content.
NFC (Near Field Communication) is a short-range wireless technology provided in the smartphone that makes your payment cards, wearables, tablet, smartphone, and other devices even smarter. Near-field communication (NFC) is the ultimate in connectivity. With NFC, you can transfer information between devices to the device quickly and easily with a single touch, whether paying bills, exchanging business cards, downloading coupons, or sharing a research paper.

The full form of NFC is - Near Field Communication
NFC definition
Near Field communication is specially Designed to provide fast, easy, and convenient wireless connectivity. NFC is already being used for contactless payments, access control, virtual event tickets, and information shared between smartphones.
The AV (Audio Visual) industry increasingly integrates mobile devices as a convenient form of system control, So we're going to see Near Field Communication becoming progressively and more popular in audiovisual (AV) devices too. Though NFC communication may seem similar to Bluetooth and WiFi, in NFC way, one of the key differentiators is that NFC has a strictly limited transmission distance of fewer than 4 cms and though this may initially sound like a disadvantage, this short-range transmission is ideal for secure and person-to-person data transfer.
What NFC is exactly?
Near Field Communication is an off-shoot of its sister technology RFID (or Radio Frequency Identification) and can be active or passive, with passive RFID devices effectively being 'read-only' - such as on NFC ID fob which will allow for its data to be read. But can't access data from another device.
Active NFC supports two-way communication between devices, allowing data to be exchanged and even updated in some circumstances between compatible devices such as tablets and smartphones, etc. The NFC Communication is this bi-directional NFC connectivity that offers some best opportunities for smart control of AV (Audio Visual) systems.
For instance, how about simply touching your smartphone to a digital room booking system. That will access your diary and automatically book the room on a series of dates? Or a conference room with a server-based presentation system, where your personal NFC (near field communication) login will automatically load your Media or presentation, set the microphone levels, set the lighting in the room, and the aircon to your preferred settings.
What is the Scope of NFC?
So the scope of NFC connectivity goes way beyond the much-publicized contactless payments and swapping of pictures from mobile to mobile. Expect to see information transfer to mobile devices from "smart posters", wireless printing from digital cameras by "touching" the printer with your smartphone, or setting-up wireless home networks without keying-in information with the help of it.
Near Field Communication (NFC) isn't just convenient, but is intuitive to supported devices, recently secure due to the limited short-range transmission, and interoperable with other contactless technologies such as RFID (Radio Frequency Identification). If you're not using NFC (Near Field Communication) in your everyday life Then start to use it from today and enjoy wireless payment through your mobile phone.
How Do NFC works?
With the introduction of services such as Android pay and Apple pay and the inclusion of this technology and pretty much any new phone or tablet NFC our near-field communication has become more and more popular every single day and is seeing more uses pop up all the time with some of its other uses including sending pictures between devices and managing your settings by just tapping your phone against an NFC tag.
Before we discuss the nitty-gritty of how NFC works, we need to know a bit more about the different types of NFC so without overcomplicating things. There are two different types of NFC active and passive active generates its power from the device's battery many NFC chips are built into batteries and phones while passive NFC receives power from an active NFC chip.
Because of their lack of power passive NFC devices can't talk to each other whereas active NFC devices can talk to each other so anyway, now that we got all that all the way this is how NFC works when NFC is switched on your phone is creating a non-harmful low-power electromagnetic field one kind of similar to the ones used in Wireless charges this field is created by an antenna through the use of magnetic induction.
So when you take your phone or other NFC device with this electromagnetic field, and place it over another active device both these chips communicate and do the tasks that you say to do, However with passive is a slightly different story when communicating with passive devices the field produced by the active device is used to power the tag attached to the NFC chip is enough storage to store things like text and links not much else. That's why passive NFC can fit into all the places that they fit into so that's how NFC works without getting too scientific all.
Is NFC (Near Field communication) safe?
If you are asking that Is NFC safe? then answer is Yes. Because NFC (near field communication) is petty (very) secure. it is potentially safer when you are using it with the biometric lock or any other lock. There is no problem with using your mobile phone to make the payment or sharing data through NFC.
Friends, if we talk about safe and unsafe, then there is nothing safe in the Internet world. Because anything is safe only when we use it with safety. There is the same thing about NFC because, according to the way of inventing NFC and the way of using it, safety will have to be given more attention. NFC means near field communication. To communicate the device within a specific range, whether you do data sharing or wireless payment, you have to take Care of safety.
Nothing is safe in the internet world. If NFC is used with securities, and care then NFC is safe and, NFC is unsafe if it is used carelessly and with no securities. Everyone can use Near Field Communication (NFC) with only required safety and Using criteria. So remove this question from the mind that Is NFC safe? Because everything has the risk of losing.
