Going Cashless? Bad for Tax Cheats, Privacy, Poor

They cite the U.S. as having 60% of purchases under $10 to be in cash. However, that should likely take in the context that many (most?) shops won't allow purchases using debit/credit cards when the purchase is < a certain minimum, usually $5 but sometimes more.

It is true though that going cashless can create a second class of citizens who can't easily enter the digital world. Despite the ubiquity of cell phones there are still almost 2 billion unbanked people in the world. I hope governments will take this into account when considering going cashless.
