1. Client Onboarding QR
A QR on the engagement letter or welcome email links to the client onboarding portal: ID verification, signed engagement letter upload, and initial document checklist. Streamlining onboarding reduces the time from instruction to billable work.
2. Secure Document Exchange QR
A QR in client correspondence links to the secure document portal for that client matter: upload, download, and digital signature of documents. More secure than email attachments and creates an auditable document exchange record.
3. Appointment Booking QR
A QR on the firm's business card and website links to the appointment booking calendar. Prospects and clients book initial consultations and review meetings without calling reception. Automated confirmations and reminders reduce no-show rates.
4. Professional Profile QR
A QR on a professional's conference badge, brochure, or speaking profile links to their full professional profile: qualifications, specialist areas, publications, and direct contact form. More informative than a business card alone.
5. Regulatory Compliance QR
For regulated professions (ICAEW, SRA, RICS, ARB), a QR on the professional's certificate or firm registration plaque links to the regulatory body's register entry. Clients and prospective clients verify registration status without navigating the regulatory body's website independently.
Putting this into practice
Start with the smallest real test you can run. Generate the code, print it at the exact size you plan to use, and scan it with two different phones in the lighting where it will live. Check that the destination page loads quickly on a mobile connection and that the call to action next to the code tells people what they will get. If anything feels slow or unclear, fix it before you print a full batch, because reprints cost more than a short test. Keep a note of the size, material, and placement that worked so the next batch starts from a proven setup.
Common mistakes to avoid
The most common mistakes are easy to avoid once you know them. Long payloads make modules tiny, low contrast makes edges hard to read, and text placed too close to the border eats the quiet zone the scanner needs. Covering a corner finder pattern with a logo or a sticker breaks detection entirely, and a code placed behind glare or on a curved surface fails even when the print is perfect. Review each of these points on a proof copy, and treat any failure as a reason to adjust the design rather than a reason to blame the scanner.
Quick checklist
- Keep the payload as short as practical so modules stay large.
- Keep dark modules on a light background with strong contrast.
- Leave a clear quiet zone on all four sides of the symbol.
- Test the printed code at the real viewing distance and lighting.
- Confirm the destination page loads fast on a phone.
- Recheck the code after any change to the link, design, or placement.
