WHAT DOE’S NFC STANDS FOR?
NFC STANDS FOR NEAR FIELD COMMUNICATION.
WHAT IS THE USE OF NFC?
Near-field communication is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm of each other.
HOW DOES IT WORK’S?
Just like Bluetooth and WiFi, and all manner of other wireless signals, NFC works on the principle of sending information over radio waves. Near Field Communication is another standard for wireless data transitions. This means that devices must adhere to certain specifications to communicate with each other properly. The technology used in NFC is based on older RFID (Radio-frequency identification) ideas, which used electromagnetic induction to transmit information.
WHAT IS THE PURPOSE OF NFC IN ANDROID?
Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4cm or less to initiate a connection. NFC allows you to share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices.
WHERE CAN WE USE NFC?
Situation-based profiles
Undoubtedly, the most common way Android owners are using NFC tags is to efficiently adjust a series of system settings based on the arrival or departure of commonly visited locations. Here are a few examples.
At home
Put an NFC tag near your door and set it to do things like: enable Wi-Fi, decrease brightness, disable Bluetooth, and auto-sync. Using NFC Task Launcher, you can program the tag to “switch,” so that when you exit your house and tap the tag for the second time, it changes those settings (like disabling Wi-Fi.)
Driving in the car
Stick an NFC tag somewhere near your dashboard or middle console and have it disable Wi-Fi, increase volume, and enable Bluetooth (for a headset). If you have your phone hooked up to the car’s speakers, program the tag to fire up an app like Pandora.
Getting to work
Place the NFC tag on a phone dock or your desk’s surface and program it to decrease brightness, disable sounds, enable Wi-Fi, and enable auto-sync. Depending on your habits, you might also have it launch a music app, open your daily to-do list, and even check you into Foursquare.
If you use the Switch option, you can tap the tag again on your way out and have it disable the previously enabled features. And, if you’re an extra attentive husband or wife, the tag can also be programmed to send your loved one a text message alerting them that you’ve left the office and are on the way home.
On the bedside table
If you have a phone dock by your bed (or want to DIY your own), place a tag near the dock and program it to disable sounds, enable any alarms, disable auto-sync, disable the notification LED, and decrease the brightness.
Working out
The fitness types might benefit from an NFC tag on their workout armband or gym bag. For zero distractions, program the tag to enable airplane mode. Or, use the tag to fire up your favorite fitness app and playlist or streaming music app.
