It’s certainly a good point that such a sign could allow easily updating fluctuating hours- assuming that said hours were updated regularly and in a timely fashion on the server.
That said- an LED or similar sign would have this ability as well, be human readable, have a predicted lifespan of hundreds or thousands of times that of the paper, and with cloud storage and data transmission being major concerns to the global electrical grid and environment- likely be better in those regards as well.
Of course, the overall cost of that system would be higher, and arguments can be made to the resource usage but I haven’t looked at numbers.
Of course a “dry erase” board or any number of physical systems that allow for numbers to be changed out would also solve the problem and take nominally more resources and ultimately less energy and have a very long service life compared to this solution as well.
Asides “trends” the main reasons I can see for doing this would involve some desire…
… to drive network traffic and/or to data mine or provide ways to present trackers, advertisements, or other motivations which do not serve the interest of the consumer looking for information on store hours. Of course such signs also have an inherent measure of exclusion against those who don’t have the money or access to “smart devices” or the services to use QR codes which may or may not also be a factor in the design. Overall while QR codes can be used to enhance or enable experiences or add convenience- allowing access to a site or service without tedious typing etc or keeping complex and frequently changing information up to date (like a menu at a location that regularly changes offerings or transit schedules etc..) I don’t think this appears to be a solid use case.
