Same sign. Different listing.
Real estate signs are expensive to produce and inconvenient to swap. A typical yard sign is $30-60; an open house sandwich board is more; a window cling on a brokerage front is a project to replace. But listings turn over in 30-90 days. Print a static QR on the sign with the listing URL, and the moment the listing closes the QR is dead — and reprinting the sign for every new property is a money pit.
A dynamic QR on the sign points to a permanent qrth.is/r/abc redirect. When the listing closes, log in, swap the destination URL to the next property's listing page, save. Same sign, new listing, no replacement. The QR keeps working across dozens of listings over the life of the sign.
