How to create QR Code in Illustrator

I tried adding a logo to the center of a code generated in InDesign, and it worked on my phone but did not work on my client's phone.

I don't understand why Express is generating SVG files of QR Codes in that manner. Thankfully the clean-up process doesn't take long, but such a thing shouldn't be necessary either.

Astute Graphics' Vector First Aid plugin isn't of much help cleaning up those QR Codes. Strangely, it sees no issues with the QR Code art when the SVG file is initially placed, even though the artwork is invisible. If the clipping groups are released Vector First Aid will see a bunch of unfilled and unpainted paths it wants to delete. That would delete all the QR Code data spots. So the QR Code artwork has to be cleaned-up manually. On the bright side, Vector First Aid can quickly delete the unnecessary anchor points after the QR Code data tiles are welded together using the Unite command.

The QR Code generator in Adobe InDesign is pretty basic, but the exported artwork is more clean than the code artwork from Adobe Express.

CorelDRAW has a built-in QR Code/Barcode generator. The QR Code feature has a lot of useful settings. The codes can be one of 8 message types (including Web URL). The QR Code pixels can be changed from squares into circles, diamonds or stars (other custom shapes can be applied to the data spots using CorelDRAW's Pointillizer filter). If squares are used they can be welded automatically. There is a corner roundness setting for squares. There are four error correction levels that can be used to generate codes (low, medium, quartile and high). There is a code validation feature. Logos/icons can be placed in the middle of the QR Code artwork. No clipping masks/groups are generated in the code artwork. If Adobe does incorporate a QR Code generator into Illustrator it should emulate or even improve what Corel did with its QR Code generator.
