I'm a backend developer who wants to shlep together some decent fullstack service for the community (entirely non-commercial): a shared library. User is supposed to scan a barcode on a book to save the book's info. I would really prefer to use web and stay away from apps for now (I don't have time to make it for different devices etc). Could I implement barcode scanner within a webpage? How would it look like? I haven't found any good examples.
You can Yulia, I'll give you a scenario of how things will work:
1- You need to prepare and generate a QR Code for every book in the library. As a developer, I think you know lots of tools which can generate free QR codes.
2- Make a separate page for every book on the system include the book name, or image or whatever. and besides this info place the QR in good size, as Whatsapp is doing check this image:
3-Then when the users in the library come to any of the computers spread in the library he/she can access the system and type the name of the book and the book page popup in front and then pick the mobile and scan the QR code and get all book info. like this:
If you want to see how this is working check this attached video for Whatsapp how to scan the QR code from mobile for Desktop version. This will give you a good idea https://faq.whatsapp.com/en/web/28080003/
Hope this will help. Best of luck!
