OCR has been failing us really badly for 40 years now, and not for a lack of trying. In fact, OCR is so bad that the one way we use to distinguish humans from machine is by forcing them to do OCR.

QR codes were designed with targeting/aligning areas as well as tons of redundancy built in, there's a reason why they can be easily scanned in realtime from a video feed at an odd skewed angle in the dark, whereas OCR doesn't even work properly on books scanned on a flat scanner.

OCR has always sucked and will always suck. Sorry.
