Ok, Lesson has started, settle down at the back.......
NFC stands for Near Field Communication. Most phones apart from really low end phones should have it built in.
If you look at your Credit or Debit card you will see a little symbol of 4 curved lines, this means that in your card you have a chip that puts out a very low-level signal that can be detected by readers.
It's what makes contactless payments work as well as access to grounds etc.
NFC on a phone is a duplicate of that system and it can also be used to link devices together, such as a phone to a bluetooth device if they both have NFC.
Next week I will be covering gravity, your homework is on the board :)
