How museums use QR codes well
A museum label has a hard limit: a visitor standing in a gallery will read a few dozen words before moving on. A QR code earns its place when it carries a visitor from that short label to something the wall cannot hold — a longer story, a voice, a film clip, or a way to support the work. The codes that get scanned are the ones with a clear reason to scan. A bare code with no explanation is easy to ignore, while a code under a line such as "Hear the artist describe this piece — 2 minutes" tells the visitor exactly what they will get and how long it will take.
Exhibit codes deserve the most care because they live the longest. A temporary exhibition label might be up for three months, but a permanent-gallery label can stay for years. Point exhibit codes at pages your own team controls, and keep the page address stable even when you redesign the site. If the page moves, the printed code becomes a dead end that no one notices until a visitor complains. Before a gallery opens, scan every code from the distance a visitor will stand, on more than one phone, and check that the page loads quickly on gallery Wi-Fi or a weak mobile signal.
Audio-guide codes solve a different problem: they replace a queue for a rented device with a page that plays in the browser. The trade-off is that visitors now depend on their own phone battery, headphones, and connection. Help them by keeping the audio page extremely light, putting the play button above the fold, and offering a transcript on the same page. Transcripts also serve visitors who are deaf or hard of hearing and visitors who would rather read quietly in a shared gallery. If your audio lives on a streaming platform, confirm that it plays without forcing an account sign-in, because a login wall in the middle of a gallery is where most visitors give up.
Ticket codes carry a different kind of risk. They are credentials, so they should encode as little as possible: a short reference that your system resolves at the door, plus the exhibition and date for human readability. Never encode payment details, addresses, or full membership records in a ticket code, since a photograph of a ticket can be read by anyone. Print ticket codes at a size that scans on the first attempt at a busy entrance, and keep a fallback — a readable reference number printed beside the code — for the moment a screen is cracked or a battery dies.
Donation codes work best where a visitor already feels something: beside a conservation story, at the end of a gallery that moved them, or near the exit after a good visit. One honest sentence about what the gift supports outperforms a generic appeal, and the donation page should be finishable in under a minute from a phone. After launch, check the basics regularly: scan each code once a season, confirm the destination still exists, and replace any code whose page has drifted into irrelevance. A small museum with twenty working codes serves visitors better than a large one with two hundred forgotten ones.
