The NFC technology allows you to exchange data between two electronic devices, such as tablets or smartphones. The devices must be equipped with NFC chips in order to function, and they must also be positioned at a close distance that does not exceed ten centimeters.
So we ask ourselves what does NFC and contactless payments mean, in detail it is a particular technology that requires a precise and detailed explanation. In this article we will go into this topic in depth, in order to explain it exhaustively, so as to understand how it works, the benefits and the fields of use of the NFC technology.
What is NFC technology
NFC is the acronym of Near Field Communication, and refers to a particular technology that allows data to be exchanged between two devices. The two technological devices communicate with each other via the wireless network, in order to send files and documents.
It is a two-way communication, this means not only that each device can transmit data but also receive them. The transfer takes place at a speed of 424 kbits per second, and is a very simple and fast system compared to e-mail, bluetooth or messaging applications.
This technology therefore makes it possible to initiate instantaneous communication between two devices that are no more than ten centimeters apart, although it is advisable to leave three or four centimeters for the complete transfer to take place.
Where is the NFC connection used?
The NFC connection it is a very useful tool and used in different fields, since it allows you to transfer files or data between two devices without using passwords or cables. Proximity between technological tools is essential for the exchange of information to take place.
Most people use Bluetooth for this purpose, but the NFC connection is undoubtedly more powerful.
If you ask a cosa serve NFC, this tool is used for transferring images, documents, files and audios between two mobile devices. Or to transfer images to a printer or from the camera to the computer.
Anyway, the NFC technology has made great strides, in fact today it can be used to make a payment, using for example Android Pay, for payments with your digital debit or credit cards. In this way, the smartphone has the same function as a card equipped with contactless for making purchases using the POS.
How to check if NFC works on smartphone
The NFC technology it is not available in every mobile device. In particular, to check if this works on smartphones, it is possible to check if the NFC icon is present in the phone’s drop-down menu. Or alternatively you can check the settings of your smartphone.
Salt’NFC is not supportedthen it is not possible to make contactless payments with your mobile phone or to transfer data, and as an alternative it is advisable to use Bluetooth, even if the latter only allows file transfer.
NFC and Bluetooth: what are the differences?
L’NFC e il Bluetooth they are two different technologies that both allow you to communicate with each other in order to exchange documents. However, it is necessary to highlight some substantial differences, in particular the Near Field Communication has a shorter range than Bluetooth, moreover the latter requires that the devices must be paired for data transmission, which does not happen with NFC.
In addition, BT has a higher risk of hacker attacks and does not work with passive devices. NFC is a safe and cutting-edge tool, also used for contactless payments precisely because of its safety and practicality.
NFC and contactless payments, what are the advantages
L’NFC in the smartphone it is one of the best technologies that could be had, as it allows you to make electronic payments and data transfer easier.
Its level of security is guaranteed by the fact that communication between the two devices takes place within a narrow range, preventing interference and unwanted connections.
Furthermore, this technology is fast, both when the two devices are identified and when the transfer takes place.
Smartphones that are supported by this tool can use it to make contactless payments directly at the POS, all by enabling your credit or debit card on your phone.
