I want to add if someone could recommend an NFC app to handle profiles (turn on/off bluetooth, wifi, etc)? I'm using My Profiles Pro but still doesn't work 100%.
To use NFC, enable it on Settings > Connections (although I think it comes on by default on BB10). Then open whatever it is you wanna share, Overflow (the three dots on bottom right) > Share > NFC. Once you do that, touch the back of your phone with the back of the other device.
Now, depending on the device you touch, it may share using NFC, it may share using bluetooth or it may just not do (*&%$. Each company seems to have its own implementation of NFC and not all of them are compatible (for one, when I got my Z10, it would not share anything to my mom's RAZR HD. Now they can use NFC to start a bluetooth tranfer of files).
