NFC: Near-Field Communication
NFC (Near-Field Communication) is a technology that delivers on the promise of connecting the physical and virtual environments. Let’s look at a video that shows how this works.
Today, you have two options to get something out of a vending machine; Use a card or use money. With NFC, now you don’t have to worry about cards or money. The transaction uses your virtual resources (in this case money) to get you that which your heart desires. It could have been anything though; you’re your online business card to a colleague; a resume to a hiring manager or check-in at a restaurant.
Today’s tech, NOT Tomorrow’s…
Here’s one you would think borders on magic. Bring your mobile phone close to the speaker and your favorite music app will start playing your playlists through your speaker. You don’t have to make an effort to start your music app nor do you have to be the one to set the streaming option to the speaker. It is done automatically. Like magic!
The neat thing about this is that it is NOT a future application. It is available today…
The Bottom Line
NFC can provide instant secure wireless two-way communication between two devices. And, if you don’t care for the security overhead, there are modes you can exchange exposed data as well.
