Is link or other information contained entirely within the pattern? I created some QR codes through one website. I didn't realize I was start a 7 day trial. I guess the site can monitor the number of times the QR code is read. How can it do that if the code is universal and free? How does information get back to the site where it was created?
Any suggestions for making QR codes without a membership?
