QR Code Generation for Invoice

[Ealfardan]

This is already achievable.

@Ealfardan

You can always use an img link in a custom field if you need a static qr code.
But if you need a dynamic qr code you should use a custom theme and a qr code api service like goqr.me . But you need to have a decent set of IT skills to manage that.

Example

I wouldn’t vote against getting a native QR generator or a QR custom field type but it has to be dynamic since every country, or even possibly every business, is going to use different texts, links or even standards.

So, more likely than not, the QR Code text string will have to be entered or coded by the user in any case.
