Is it possible to Connect a QR code to an offline Database?

Question

I would like to ask if a QR code can be used in order to access to the information stored in a Company internal Database; all of that without using internet (just in case it goes down).

Answer 1

QR code is just a scanned code of an url, you can make a webpage that accesses localhost server and local database whenever there is a request.

Build your QR code of the localhost link and scanner from these codes:
