QR codes that follow your training program
On a printed handout, a QR code sends people to what doesn't fit on paper: the video, the answer key, the file to download, the questionnaire. And since the content changes from one session to the next, the dynamic code saves you from reprinting the binder.
Concrete ideas
- One code per chapter leading to extra resources, updated every year
- An "answer key" code that points to a "not available yet" page, then to the answer key after the session
- A code on the classroom door leading to the day's schedule
- A code on the evaluation sheet leading to the feedback questionnaire
- A wifi code for trainees
- A PDF code to the course material, replaced with each new version
Why dynamic
The resource's address changes, the platform changes, the answer key isn't published until after the class. With a dynamic code, you pause, edit, replace, and the printed handout stays valid for years. The stats tell you which chapters people actually check.
Print size
On an A4 handout held in the hand, 2 cm is enough. Projected on screen, make it large (a third of the slide) and leave it up long enough for everyone to scan.
| Medium | Reading distance | Minimum code size | Tip |
|---|---|---|---|
| Business card | 15 to 25 cm | 2 cm per side | Reserve a corner, keep a 3 mm white margin around it |
| Table tent, menu | 30 to 50 cm | 3 cm | One code per medium, never two side by side |
| A5 flyer, product label | 40 to 60 cm | 4 cm | Avoid busy photo backgrounds behind the code |
| A3 poster, shop window | 1 to 2 m | 10 cm | Place it at eye level, not at the bottom of the poster |
| Roll-up banner, tarp, vehicle | 3 to 5 m | 25 to 40 cm | Simple rule: distance ÷ 10 = code size |
Common mistakes
- Encoding a file's address on a shared drive that will get reorganized, as static.
- Not saying what people will find behind the code: a "Scan for the menu" doubles the scan rate compared to a bare code.
- Linking to a page that isn't built for mobile: the scan succeeds but the person leaves right away.
- Removing the white margin around the code to save space: this quiet zone is needed for the scanner to work at all.
Frequently asked questions
Can I create a lot of codes quickly?
Yes, the CSV import (Pro plan) creates hundreds of codes at once, with one folder per module.
Do the scans identify individual trainees?
No. The stats are anonymous: number of scans, country, device, time.
Can I share management with colleagues?
Yes, on Pro (3 members) or Business (10 members), each with their own account.
