Now several decades later I have again fallen in love with the secret code and decoder.
Forty-five years ago no one would have dreamed of a hand held device with all of the features of a smart phone, that when pointed at a 2D bar code would also be the modern day equivalent of the decoder ring.
A secret is only a secret if no one or very few people know of it. You may have seen my 2D Tag art before and not realized that you were actually looking at a 2D bar code.
I would bet that you don't recognize the custom 2D Tag that is accompanying this article as anything but a pretty picture. Think of the smartphone as your modern day decoder ring and the image as a secret code. Using the Microsoft Tag Reader app and with your decoder you can unlock the "Top Secret Message."
The kind of things that kids can only dream of and that only a kid at heart could have dreamt up.
Scan the "Secret Code" with your Tag Reader App to unlock the message.
