Thought of this more recently. The amount of control tech has over credit or debit cards is dangerous. Not to mention a power outage leaves you with nothing. Or if someday companies decide you can’t use their credit card certain ways.
Its kind of unfeasible today, but maybe we should be using cash for every possible thing…


If it would be a concern for you, I’d imagine that ATMs probably scan bill serial numbers.
Certainly. It still muddies the water.
