We check your code scans before you print it

Design choices can quietly break a QR code: too little contrast between the pattern and the background, a logo covering too much of it, or durability set too low. As you design, QR Cake now reads your own code back the way a phone camera would and tells you when it will not scan, or when it may be hard to scan. Every suggestion is a link, so choosing to make the logo smaller, put it behind the code or raise durability takes you straight to that control and highlights it.
