a) I do not see how having 'electronic signs' would be a good idea. Why bother updating a LCD or so with a QR code if you could just as well use BlueTooth to communicate? The latter likely is more robust and cheaper. b) The idea is not to have electronic QR signs, it is to have QR signs that contain something like a URL that contains up-to-date info about a place. Replace that URL by your own, and have fun :-) |
