1. We can use the same QR code to contain information without accessing the internet, and access the internet by containing basic information without using internet access in a URL
2. In this way, we can already retrieve the information without accessing the internet. Depending on the size of the QR code, it can store from 300 to 4296 alphanumeric characters.
3. When we use the URL to access the internet, it can point us to google forms. I have created my own google form page with customized text of “stockceck” with the link https://docs.google.com/spreadsheet/viewform?formkey=dHNLY2FUX0FSLVJJbXlNNjcxVXZ2ZGc6MQ&entry_1=stockceck , the corresponding QR code is below
4. In fact, we can create our own QR code for free using google charts. I just created one with text “YouRulesforever: with the link http://chart.apis.google.com/chart?chs=150x150&cht=qr&chl=YouRulesforever&choe=ISO-8859-1
5. Being able to create QR code with a url means we can develop applications using QR codes with some simple programming.
6. This capability can also complement existing GS1 bar code standards.
