Le NFC

It is reported that more and more nomadic products will be compatible with NFC. To find out what this abbreviation is, read.

   NFC, or Near Field Communication, is a technology that will be widely deployed on all mobile devices in the coming years. It's safe to say that NFC will eventually be implemented by default on all smartphones, tablets, and connected audio and video players, as well as Bluetooth or WiFi, for example.

   NFC lets you establish a connection between two compatible devices at a short distance (10 cm maximum). This method is used based on short wavelengths. The principle is not different from that used in Navigo cards in the Parisian transport, although the technique varies. Many possible applications, I suggest you look at each other in particular:

      With NFC, you can do this:

- Forget a bank card, car key, ticket, loyalty card. You can use your smart phone as a way to transfer, pay when you sign out, sign up or use loyalty points when you shop in your favorite store (VNAC, of ​​course ...).

All information will then be stored on your phone's SIM card. The fact that NFC includes a very short distance to use provides certain security, without counting of course for encrypting and encrypting data. Moreover, all studies show that one notices faster losing or forgetting his smart phone than a card in his wallet. The vast majority of today's mid-range and high-end smartphones benefit from the NFC chip. The beginner models also enter the dance.

   - Much like Flash Code, but more simply and with a wider range, NFC lets you, by making your mobile compatible in writing, access information about products you're interested in tracking on a food product, an environmental footprint on a game, -Ray, competitive prices for a PC, applications seem to be endless. In the same way, we can tell the actual time of waiting for the next bus in an equipped bus shelter, or get information about the artist during the show. It will be understood, the NFC will devote the interactive era in real time.

   - In an area of ​​particular interest to us here, the NFC allows two compatible communicators to be connected, for example to connect a portable reader and a wireless speaker, with no less configuration, other than Bluetooth that requires both devices to recognize themselves and communicate (we are talking about pairing). NFC allows them to share information, URLs, links, and so on. However, multimedia content or files can not be transferred for reasons including low speed.

   - After-sales service and technical assistance for NFC devices will be greatly simplified. Let me explain, no need to get out of the polytechnic to explain the technical problem of your problem-solving device on the phone, you can make the NFC smartphone closer to the NFC device, it collects information, it is only necessary to send to the technician, to save time and efficiency. Why not, in the other direction, consider receiving a reprogramming technician from your device that you are entering through NFC? Real dream, immediate and remote repair!

The uses we have just seen, which are just a sample of the possibilities offered by NFC, herald the announced success of this technology. But, because there - but should not obscure the inherent flaws in this development.

       NFC defects

- Security, a weak link in electronic payments. The loss or theft of your smartphone, which is actually harmful in itself, will also mean loss of payment method, transport card, etc. Given the return of thefts to laptops at present, the issue of danger arises. Should we put all his eggs in one basket?

- You can also access information through the NFC, it also allows you to collect information about you, your purchases, your travel, and your consumer habits. We can easily guess the commercial use that can be made of this information, without the consumer's knowledge or real control. You do not even talk about violations of privacy and personal data.

- There is still a lack of perspective on change management operator, data transfer, banks or otherwise. Under what security conditions will the transfer be made, and at what cost? Is it really advisable to entrust his operator with as much sensitive data?

- The usual functions (transport card, loyalty card, etc.) are available on the deactivated smartphone. On the other hand there is no solution at the present time for payment which requires the input code, and thus the device is powered.

It is necessary to provide a strict framework for this new technology by the legislator and the National Commission on Computerization and Freedoms (CNIL) to ensure consumer protection. With regard to security, the reservations I mentioned were already relevant prior to the circulation of the bank card or payment on the Internet. This did not hinder its development. After being jointly launched by Sony and Philips, we can only hope for NFC the same success achieved by previous collaboration between the two giants, a CD.
