Wall QR code

One sticker. Permanent. Checked on site.

The wall QR code hangs in your reception, at the counter or in the treatment room. Whoever scans it leaves a review in under a minute — and on submission the location is checked against your business address.

This is how a review appears that was given via the wall QR code at reception.

4 out of 5 · Experience on 12 September 2026

It was my first time there and, to be honest, I had low expectations, because I have been through quite a lot with appointments of this kind. I was booked in for a quarter past ten and was seen five minutes later — unusual enough in itself, for me. At reception someone explained what to expect and roughly how long it would take, instead of just pointing me to a chair. The treatment itself was calm and thorough; I was asked in between whether anything was uncomfortable, and when I said yes, they did in fact stop. What I particularly appreciate: at the end I was given two exercises for home, written down and not just demonstrated quickly. The follow-up appointment was available in the same week. I will come back.

Why the wall QR code is the baseline

It costs nothing, goes up once and collects continuously from then on.

Included in every plan

In the free Basic profile too. One per location, with no quota and no surcharge.

Location instead of trust

On submission the server compares the reported location with your address. Anyone who was not there does not get through.

Print once, use for a long time

The code is valid for two years and can be scanned as often as you like. A sticker, not a consumable.

Three steps to the wall

  2. 2

    Download the code

    As PNG, SVG or a ready-made PDF sign — with your logo if you like.

  3. 3

    Put it up

    Where guests are waiting anyway: reception, counter, waiting room, checkout area.

Where the wall QR code ends

It always checks against your business address. At a trade fair or an open day elsewhere that fails — the event QR code is there for that, with its own venue and its own time window.

And it rates the business as a whole across four dimensions. Anyone who wants a single product or a particular service reviewed uses the product QR code.

Put it up.

Create the Basic profile, download the code, hang it up. That is all it takes.
