I struggle to think of what that extremely secure infrastructure would look like. Are you imagining signing on an electric terminal and having a computer compare signatures at the time of sale? That seems like the most secure and still wildly insecure compared to a pin.
And, the next ultra-big step: How would a non-techie figure this shit out?
They don’t have a computer, another computer with a different OS, or bitwarden.
Do you think signatures were at all secure? If they cared about security they’d do chip+pin like most civilized countries.
You can’t see something small right behind you with that.
Yeah. I’ve been able to do it since I was 10. It’s really easy. I can also fake my husband’s and siblings’. It’s also a pain in the ass to change your signature. So if someone learns to copy it (like say based on the signature that was literally required to be on the card), it’s much hard to change it compared to a pin (which should definitely not be written on the card).
