I’m expecting that if she has been scammed and her token was stolen, you can report this token to the police and they might be able to ask the banking system in which account was this token deposited, to hopefully trace the scammer back.
If so, this looks safer than the scams that ask grandmas to get giftcard codes.
But that’s assuming that the token was obtained from grandm’s bank and not that the grandma paid a scammer in some other untraceable way to obtain a fake token from the scammer. That would be a different kind of scam.
The approach to taxing isn’t determined by this tool, but by the government. What this tool tries to prevent is hidden money exchanges, which affect both methods of taxing, not only flat taxes but also income-based taxes (since a hidden sale is giving the seller a hidden income and potentially placing them at a lower income tax class).
