The questions that actually come up when QR codes and barcodes meet real menus, labels and packaging, answered the way we'd explain them to a customer.
Static vs dynamic QR codes: what should you print?
The difference without the sales pitch, plus a decision rule you can apply in about a minute.
QR code not scanning? Work through this list
Our own triage order for dead codes: print problems first, file problems second, destination last.
How big should a printed QR code be?
The distance rule, the density caveat and tested minimums for cards, menus, posters and signs.
QR error correction: what L, M, Q and H actually do
Reed-Solomon without the math, the density cost nobody mentions, and honest defaults per use case.
Barcode types, explained: which format does your label need?
Retail, logistics, books and the 2D family sorted by job, with the GS1 caveats spelled out.
QR codes for restaurants: menus, reviews and payments that get scanned
What survives actual service: stable menu links, table tents that outlast wipe-downs, review codes with timing.
