Dear QR Code Reader Companies.
When someone scans a QR Code with your reader, please stop loading the page people are trying to visit within your reader. Various JavaScript and location prompts necessary for page display, location, or other services to work are blocked as a result. A scan of a URL-type code is best launched on the phone’s native browser.
While it is true your reader may allow the person scanning the code to break the intended URL out of your reader - I suspect most people do not realize they could or should do that.
The average consumer will never understand why something is not working properly and brands are getting annoyed that their carefully crafted experiences are being bastardized by you.
You know who you are.
