Re: Easy to copy
You can copy any QR code, and the copy will have the exact same information, and will look equally Valid.
What you’d need is a database that not only checks the QR code but also returns a picture, name and address of the person. Or an app for checking that sends the location, and if the same QR code is used in different locations then it’s blocked. So if you share your QR code it stops working for yourself. You can make and use one copy of your grandmas QR code as long as she stays at home and doesn’t use hers.
