4th Amendment for the 21st century

[Egnever]

3. There are unintended consequences

No matter what, this is not an easy nut to crack.

In just your example I can see problems. For one if they made visa or mastercards resemble cash transactions it would remove a lot of the info they use to detect fraud. My card number was recently compromised and they caught it almost immediately because they were aware of my spending habits. Take that away and the amount of fraud would skyrocket overnight.

It is an incredibly complicated problem. I only hope any laws proposed or passed are carefully deliberated and thought out and like I said not a kneejerk reaction to something.
