About This Book
The good news is that the journey you and I are about to begin isn’t like Frodo’s. You don’t have to worry about any danger, powerful wizards, or heavy burden to save the world. All that’s required for this journey is curiosity.
You may be one of the millions of people who’ve already scanned a QR Code, but you’re wondering, “How can I use QR Codes, and what possibilities do they hold?”
