Reviews with Display Verification
The McGesund reception display shows a rotating, cryptographically signed QR code right on-site. Guests scan, review — you have the proof that every voice comes from your premises.

Simulation. On the real display, the QR code rotates every 7 seconds, and each variant carries a post-quantum signature.
Why a rotating display?
Three properties that a static QR sticker on the door cannot deliver.
Rotating code
Each QR is valid for only seconds and is replaced by the next. Photographing it, saving it, scanning it later — that doesn't work. You only receive reviews from people who were truly on-site.
Post-quantum signed
Every code carries a cryptographic signature that cannot be forged even with future quantum computers. Every review can be checked for authenticity afterwards — without you having to do anything.
Right at reception
The tablet sits where your guests are already waiting — at check-in, at the front desk, in the waiting area. A single gesture is enough, and the barrier to leaving a review drops considerably compared to a later email reminder.
