Seems like the NFC class includes Singleton, correct?

  require 'singleton'
  class NFC
    include Singleton
    # ...
  end

You could simplify your public API (by not requiring users to type 
.instance) like this:

  require 'singleton'
  NFC = Class.new do
    include Singleton
    # ...
  end.instance
