Where codes genuinely reduce workload
- Forms, reached from the paper notice rather than found through a website menu that assumes you know the department's name
- Service reporting, where a code on a bin, a lamp post, a bus shelter or a park bench reports the fault with the location already attached, which removes the hardest field on the form
- Permits and parking, where a code beside the bay is faster than a phone line
- Appointment booking for counters and clinics, cutting queue time in physical offices
- Notices, where a printed sign carries the summary and the code carries the detail, updated as circumstances change
- Library and community services, where a code on the shelf, the door or the noticeboard opens catalogue, events and opening hours
Language, which is not optional
A printed notice can carry two languages. A hosted page can carry as many as the population speaks, at readable size, with the phone choosing automatically. For any authority serving a diverse population this is the strongest single argument, and it costs less than reprinting multilingual signage.
The multilingual guide covers how the detection and fallback should behave.
Accessibility as a requirement, not a feature
Public bodies are usually held to formal accessibility standards, and a QR code programme has to meet them:
- Never make the code the only route. Print a short URL and a phone number beside it, always.
- Real alt text and a text alternative, since a square means nothing to a screen reader. The alt text guide covers the wording.
- Placement at 1.2 to 1.4 m, reachable from a wheelchair.
- High contrast, matte, and large, because outdoor signage is read in poor conditions by people who are not looking for it.
- Destination pages must meet the same standard as the website. A code that opens an inaccessible PDF fails the whole exercise.
Never require an app
The moment a scan demands an app download, the service excludes people with full storage, old devices or limited data. Everything should work in the browser the phone already has.
Trust and the sticker problem
Fraudulent codes stuck over official ones on parking meters and payment notices are a widespread scam, and the public reasonably assumes an official sticker is genuine.
- Resolve only to official domains, published and consistent
- Use tamper-evident material and inspect it on a schedule
- Never ask for payment card details on a page reached from a scan without an intermediate official page the resident can verify
- State clearly, in the same signage, what the code will and will not ask for
Measurement, within the rules
Scan data is useful for planning: which notices are read, which locations report faults, where demand actually is. It is also personal data. Keep collection minimal, retention short, and follow the same consent posture as the organisation's website, as set out in the scan tracking guide.
Roll out QR codes in a public service organisation in 4 steps
Start with fault reporting and forms
A code on the asset reports its own location, which removes the hardest field on the form and the longest call.
Print a URL and a phone number beside every code
The code is never the only route. That single rule keeps the programme accessible and lawful.
Serve every language automatically
One code, one page, as many languages as the population speaks, at readable size on the phone.
Use tamper-evident print and official domains only
Fraudulent stickers over official codes are a known scam. Publish your domains and inspect the signage.
Frequently asked
Should a public notice rely only on a QR code?
Never. Print a short URL and a phone number beside it. Some readers have no smartphone, no data, or use a screen reader that cannot interpret an image.
How do QR codes help with fault reporting?
A code on the asset itself carries its location, which removes the field people get wrong most often and shortens the call it would otherwise generate.
How do multilingual communities benefit?
A printed sign can carry two languages. One code opening a language-aware page serves as many as the population speaks, at full readable size, for less than reprinting signage.
Are QR codes accessible enough for public sector standards?
Only when they are one route among several, carry real text alternatives, sit within reach at 1.2 to 1.4 m, and open destinations that meet the same standard as the website.
What about fraudulent stickers over official codes?
Use tamper-evident material, inspect on a schedule, publish the official domains your codes resolve to, and state on the signage what the code will never ask for.
