Page 208 in PDF version - ‘For now, the data encoded in the QR code is irrelevant; you just need something to detect.’. Nowhere in the book did you talk about data encoded in QRCode. Then what is the difference between detecting a normal rectangular surface and QRCode if you are not reading QRCode’s embedded data?
If you’re not using or reading the data encoded in the QR, then your concern is legit, there wouldn’t be any reason to use a QR.
In the RazeAd app I wanted to point out that you can embed data in the QR, and that you should use QR codes for that purpose, but I didn’t actually use that feature in the app - if you scan the QR code provided in the book (you can use your iPhone camera), you can see that its content is “Hello, RazeAd !!!”.
Probably I should have given a real example - it could have been something as simple as embedding a URL. Note taken.
Thanks for pointing that out.
Do you plan to add an example ?
