Or, email this link to QR Code:
A QR code is a code that when read by a smartphone’s camera, will download a program, give them a message, take them to a website (like this one), or many other things. QR codes are now on some products, and it will pull up a list of every store that product, for comparison shopping.
Nowadays, it costs no money to make a QR code, like this one. It was made from http://qr.zeemind.com/, which runs a free QR code creator, and as an extension for Chromebooks/Google Chrome. They are useful, as they can hold any type of data, and can even be used as a signature for a email!
