QR variants supported by MLKit?

[hanspeide]

I'm wondering what QR variants (model 1/2, micro QR, Frame QR, etc.) are supported by MLKit? Afaict, the docs only specify "QR", and not variants.

ML Kit does not support these variants today. To understand better, what specific use cases would supporting these be important for? Thanks!

[chrisito]

Friendly ping, we would love to know your use case. Thanks!

I would like it to support all types of Qr code

Seems like Model 1 doesn't work, but Model 2 (standard QR codes) is no problem, as expected.

Model 1 symbols are deprecated and should no longer be used in anything other than close applications.

"Frame QR" is a proprietary standard.

The QR Code variants that are ISO standards are:

• Micro QR Code (defined in the parent symbology standard)
• Rectangular Micro QR Code (ISO/IEC 23941)

The latter may be especially useful in future "2D in retail" scenarios if support becomes ubiquitous.
