A code that changes with the running order.
Before the doors open it is registration. During the event it is the schedule. Afterwards it is the feedback form. Same wristband, same poster, same code.

Where it gets used
Wristbands and badges
Scheduled destinations that move through registration, programme and feedback without anybody touching anything on the day.
Venue posters
Stage times that change at short notice, updated once and correct on every poster in the building.
After the event
Point the same codes at photos, recordings and next year’s tickets.
Why it has to be dynamic
An event has three or four distinct phases and one print run. Scheduling the destination is the difference between one code and four.
A dynamic code encodes a short link that belongs to you. The pattern is fixed at the moment you print it and never has to change again — you change where it leads, as often as you like, and every copy already in the world follows.
Code types that fit

- Link in bio
- Feedback
- Image gallery
Each brings its own fields, and the ones that need a page get a hosted mobile page you edit yourself — no website of your own required. See all the types.
