Putting a Demo Behind a QR Code
August 28, 2026
Everything else in this category assumes a browser. Sometimes your audience is standing in a conference hall, holding a leaflet, or looking at a poster.
A QR code is the only bridge from there to your product, and most point at a homepage — which spends the one scan you earned on an introduction the person just had in real life.
Where the scan comes from matters
Somebody scanning at your booth has just spoken to you. They do not need the pitch again; they need the thing they were told about, immediately.
Somebody scanning a poster has had no conversation at all and needs context first. Same code, different destination — and using one link for both wastes the harder-won of the two.
Build for a phone, in a hurry
- Assume a phone, held one-handed, in bad light.
- Assume poor connectivity, which conference halls reliably have.
- Assume thirty seconds, because they are standing up and somebody is waiting.
- Assume no signup, since nobody creates an account while standing in a queue.
Put the ask at the end
The point of a scan at an event is usually to continue the conversation later. Ending the demo with a lead form is a reasonable ask at that moment, because they have just watched something.
A form before the demo, by contrast, converts an already-warm person into somebody who put their phone away.
Use a distinct code per placement
Different codes for the booth, the leaflet and the poster cost nothing and tell you which physical thing actually worked.
That is the only feedback offline material ever produces, and most teams give it up by printing the same code everywhere.
Frequently asked questions
- What should a QR code at an event link to?
- A demo, not your homepage. Somebody scanning at your booth has just spoken to you and does not need the pitch again -- they need the thing they were told about, immediately and on a phone.
- Should I use the same QR code everywhere?
- No. Distinct codes for the booth, the leaflet and the poster cost nothing and are the only feedback printed material ever gives you about which placement worked.
- Should a scanned demo ask for an email?
- At the end, yes -- continuing the conversation later is usually the point of an event scan, and they have just watched something. A form before the demo turns a warm person into somebody who put their phone away.
