This is a great idea, thank you for your proposal. A few comments/suggestions;
1. Would it be possible to use the QR code for non smartphones? You say this can be used all over the world but in many places, a lot of people have phones that are not smartphones.
2. Is QR an acronym? If so, please spell it out when you first use it so all the readers are aligned on what it is.
Best of luck!
