- gregsadetsky 5y agoThanks. Looking into it [0], the QR code I'm testing uses the "up to 7% damage" error correction level L, which makes sense since there's already a lot of data being packed in the (vax proof) code. ... I still want to find a debugging/verbose QR decoder :-) [0] https://blog.qrstuff.com/2011/12/14/qr-code-error-correction https://blog.qrstuff.com/2011/12/14/qr-code-error-correction
