I think the shenanigans referred to are on the part of the merchant (not reporting income, stealing from the till or enabling bribes) rather than the consumer (card fraud, etc.)

There's something like 2 trillion dollars laundered annually, and a lot of this happens through shops that use anonymous cash transactions to do it.

Source?

> "The estimated amount of money laundered globally in one year is 2 - 5% of global GDP, or $800 billion - $2 trillion in current US dollars. Though the margin between those figures is huge, even the lower estimate underlines the seriousness of the problem governments have pledged to address."

I meant source for "a lot of this happens through shops that use anonymous cash transactions".

$2 trillion in $10 bodega transactions is 200 billion bodega transactions. Something tells me it's not the silver in the till that's the main problem. Or even the notes.

Agreed. Plus there's a complete loss of anonymity with ubiquitous credit card use.
