NFC stands for Near Field Communication English, a wireless communication technology for transferring data between devices without touch. NFC works by antennae placed on compatible devices using the band of 13.56 MHz and offer a virtually instantaneous connection.
The first we saw with NFC mobile dating from 2008, some Nokia models. In 2010 he joined the Nexus S. Current models can be found in the impressive Samsung Galaxy S III. So far all we have seen use of NFC technology has been to make prompt payments and therefore replace the "obsolete" credit cards.
NFC in Apple
To date, Apple has decided not to incorporate the NFC system in its smartphones, even saw as The Wall Street Journal reported that Apple might be delaying the payment with mobile deliberately. But it seems that this will change with the iPhone 5. Among the rumored features of the new Apple smartphone includes support for NFC. Inclusion on the iPhone this technology could be the boost it needs NFC to take off for good. But we know that Apple always tries to climb a step higher than the rest, and since 2009 we have seen the Cupertino patents in using NFC technology for much more than being a virtual payment system.
Not only pays for
Apple seems to want to use the NFC technology in home automation, for example, control heating and air conditioning, turn on automatic watering the garden, the garage door open, using remote cameras and more. Moreover, as we see in the picture, also could be used as a substitute for Bluetooth devices to connect to each other. Use automation to see what Apple intends complicated, since the distance to link NFC devices is only 20 inches, unless Apple invents something to extend this data.
Currently used for
As mentioned before, the main use that is being given now to the NFC is to make payments as substitutes for the cards. But not alone. In Japan they have vending machines that support NFC as a payment system. We have also seen some Spanish developments using NFC technology to link with RFID chips (the alarms used in stores) to approach a product to tell us all the features. Some metro networks such as London or the use of Valencia NFC system. The bike rental system in Barcelona is also used. And even some hotels have NFC chips as a system of opening the doors of the rooms.
Another curious example of using NFC stickers we call intelligent. Stickers are equipped with NFC chips that can hold information in it or configure them to perform some specific action when approaching any device. If you are curious here ye can see.
As for future uses that could be given we can find a replacement travel pass for the subway or the bus (as is done in some cities), completely replace credit cards and cash, or, even able to use it as a key to enter the car or the house (though the latter I see something dangerous, is more common than steal your mobile keys). In short, make our smartphones are fully integrated and completely necessary in our daily lives. That would be the big challenge for technology companies.
We know that Steve Jobs talked about the post-PC era, a time when we did not need computers to almost nothing. It is clear that Apple has spent years researching the uses could be made of this technology. So far not even extended to her that in the stores and virtual wallet. Perhaps if Apple will implement it in its iPhone 5 begin to see greater numbers, but still a long way to go.
