Measured answers about QR codes — what they cost, how they behave, and what the vendors do not put on their pricing pages.

- What a dynamic QR code actually costs per monthEntry-plan prices for four QR code vendors, divided by the number of dynamic codes each plan includes — the per-code number none of them print on their pricing page. · Pricing & cost
- Do photo QR codes actually scan? Our decode-test resultsA QR code that is a photograph sounds like it must scan worse. We measured ours with a real decoder — blurred, shrunk, and read the way a reader reads. · Printing & scanning
- How big can the logo on a QR code be? We measured it"30% error correction" is not a logo budget. We punched growing holes in codes at every EC level until a real decoder gave up, and recorded where it broke. · Printing & scanning
- How small can a QR code be printed? The sizes, computedThere is no single minimum size for a QR code. We ran five real payloads through our own encoder for the module counts, then turned those into millimetres. · Printing & scanning
