Equinox, the developer of Mail Designer Pro, has uncovered a secret formula used by Apple to create scannable promo codes for the App Store.



If you've used an iTunes Gift Card, you may have used your iPhone's camera to scan the code and quickly redeem it. Turns out, it's a bit complicated to create that scannable code.



The first factor is the font. Turns out there is a hidden font you need to use. After a lot of searching, Equinox discovered its called 'Scancardium'. If you're on a Mac you can find it here: /System/Library/PrivateFrameworks/CoreRecognition.framework/Resources/Fonts/.







Your promo code must be in the Scancardium font and it must be inside a box with some pretty specific sizing. The surrounding box must be a ratio of 3 width to 1 height. The thickness of the box border must be a factor of 0.045 and the font height inside the box must be a factor of 0.34.



To make things simpler, Equinox has created some templates in Sketch and Photoshop for developers to use. You can download the templates from the link below. They've also posted a FileMaker template to make it easy to generate your own codes.
