QR codes have definitely become part of everyday life. I mostly use my phone’s built-in scanner, but I’m always careful before opening unknown links since QR scams are becoming more common.

It’s amazing how they're now used for everything from payments to restaurant menus. For anyone interested in digital services and online registrations, I also found this useful resource: https://pseronlineregistrations.pk/
