NFC tags

What are NFC tags?
They are a near field communication application, made by Samsung, that you can use with mobile smartphone devices

How do NFC tags work?

NFC tags are considered passive devices,which means that they operate without a power supply of their own and they come in range before there activated. Also with one touch NFC tags can turn the volume down, disable vibrate mode, deactivate bluetooth and set the brightness.

Where are NFC tags used?

They are used with NFC systems.They also combined into all sorts of products: posters promoting circus tour dates, ski lift passes, stickers, business cards, prescription bottles and even ruggedised labels meant for outdoor use. Also with one touch NFC tags can turn the volume down, disable vibrate mode, deactivate bluetooth and set the brightness.


What is so good about NFC tags?

Whats good about NFC tags is that they can be locked so once data is written onto it, it can not be altered. If you want to disable WiFi to save battery when you leave home? Put a tag near your front door. One other thing is that if you put a NFC tag in your car you can just swipe and go and it will unlock your car 

What is something bad about NFC tags?

Sometimes the phones struggle to pick up the tags 75% of the time , you have to close for it to work, if you drop your phone someone can go up to your car and unlock it.
