A scan opens your real estate listing on any phone, with the virtual tour and a booking link one tap below.

The sign maker needs the code before the brochure is final — and that's fine, because the file behind it can change later.
Why a code printed on a sign can open a PDF that didn't exist when it went to print: How QR codes work

Open the downloaded file to add it to your contacts.
The address and your agency sit above the first page of the listing, so someone standing on the pavement knows they have the right house before they open anything. One tap opens the whole PDF in the phone's browser — no app, no download, nothing to sign in to.
Under the listing go up to 3 links: the virtual tour, the listing page on your site, a calendar to book a viewing. On Pro, a contact card sits between them with your name, phone and email — buyers can call from the page, or save you to their contacts and find you again after the viewing.
Anything a buyer or tenant would otherwise ask you to send. One PDF per code, and the page can link to the rest.
Photos, price, rooms and features in one document. It is what the sign advertises, so it is what the scan should open.
The page buyers zoom into most. On a phone they can pinch in on a single room without asking you to email the file.
Hand them out at an open house without printing a stack for every visitor. If a document is revised, replace the file.
For rentals: the lease terms before a viewing, or the move-in guide on the door of a unit that is already let.
Prices on a new development change with every release. A hoarding printed once can open whichever price list is current.
Not a listing? Any document works the same way: QR code for PDF
A code printed on a sign or a flyer cannot be edited, but the file behind it can. When the price drops or the listing goes under offer, upload the new PDF and every printed code opens it from the next scan. Replacing the file is free on every plan, and earlier versions are kept.
When the property sells, the sign does not have to go in the bin. Replace the listing with the next property, change the address above it, and the same printed code on the same sign opens the new one.
A common rule of thumb is a code about a tenth of the distance it is scanned from. Keep it dark on a light background, with the empty margin around it intact.
Most people step up to within 2 m (6 ft) of a sign to scan it, so print the code about 20 cm (8 in) across. Choose Highest error correction: a sign spends months in the rain and sun.
Scanned through the glass from arm's length or a little further: 5–10 cm (2–4 in). Print it on the white of the card, not over a photo of the house.
Held in the hand, 2.5 cm (1 in) is enough. Put it beside the price, where the reader is already looking.
Keep it at 2 cm (0.8 in) or more; below 1.5 cm most phone cameras stop resolving the code. The back of the card has room for it.
Free is a plan here, not a trial with a clock on it. Three codes stay yours, keep resolving, and never carry an advert. Here is exactly what each paid plan adds.
