Sunday, 4 pm, outside your property window
A couple stops in front of the two-bedroom flat in the top left corner. The price works for them. They want to know if there is a lift, what the service charge is, whether the parking space comes with it. The office is closed. They take a photo of the listing, promise themselves they will call on Monday, and the week goes by.
With one QR code per listing, the question goes out straight away. The assistant answers in a few seconds with what your property details contain: floor, annual service charge, EPC rating, parking. If the couple want to see the place, they leave their name and phone number. The conversation no longer ends on the pavement.
The same passer-by might be a foreign buyer on holiday or an expat moving back. The assistant answers in their language, from the same information, without you translating a word.
