One QR for the studio floor, or a personal one per referral code. Ink on cream, monogram in the middle, sized for print.
Destination URL
The live public address. Leave as is; the studio tile encodes this.
Referral code · optional
Leave empty for the studio-floor QR. Add a code to mint a personal QR: it opens the booking form with the code already filled, nothing to type. One QR lives here at a time; generating a new one replaces it on this screen. Printed or saved tiles keep working.
Assign next code · the in-room ritual
Type the participant's email and press assign: the register takes the next free code and records the owner. You get the code and their share link; the fullscreen QR waits one tap away for when a friend is standing there.
The share link is the form with their code baked in: send it however they share. The QR is for a friend standing in the room right now.
Top up codes · only if the hundred run dry
Mints fresh codes (same alphabet as the original hundred) and writes them straight to the CODES tab, unassigned. The register skips any duplicate automatically. Nothing shows on screen; assignment stays its own act above.
Error correction level H, so the monogram never costs a scan · quiet zone respected Ink modules on cream: the high-contrast direction every phone camera prefers Print at 8 cm wide or larger for reliable scanning from a hand's distance
