Honestly, I don't think BMF.io has a built-in way for instructors to create QR codes for their courses. But that's no big deal because instructors can just make their own QR codes using free tools online. They can link those codes straight to their course page, so anyone can just scan it with their phone and boom , they're right there ready to buy. It's a pretty easy hack if you want to share your course quickly in person or on social media. So yeah, even if BMF.io doesn't have this feature officially, instructors can totally DIY it and make selling their courses a lot simpler.
