Barcodes are different from QR Codes regarding bits of data that can go missing. Lose one stripe of a bar code and it will be invalid. QR Codes can be generated with certain amounts of error correction built in; they can still work when missing some data spots or when a logo is covering up the middle of the code.

I didn't know this, but had to test it. You can indeed lose a significant amount of small squares and still read the code.

That's what I would be most worried about...losing some of the squares either from weeding or from weather, etc. Good to know!
