Many businesses hate cash, because cash transactions take longer to process, and large quantities of cash pose a security risk. If you travel by air, you've experienced this first-hand. "Cashless cabins" are the rule for most airlines. You must purchase every glass of wine, cheese dip, or package of mixed nuts with a credit or debit card.

In Atlanta, you can't even buy a hot dog at a pro football or soccer game with cash. In March, the operators of Mercedes-Benz Stadium, home of the Atlanta Falcons and Atlanta United, announced it would no longer accept cash at food and beverage concession stands.

Credit card companies hate cash too. And for obvious reasons – they get a cut of every purchase through the fees they charge businesses. So it's no surprise that in 2017, Visa announced its "Cashless Challenge" and gave $10,000 to 50 small businesses that stopped accepting cash payments.

Big brother hates cash, too. For decades, governments around the globe have engaged in a War on Cash. The original justification for this war was to fight racketeering. The War on Cash then morphed into the War on Drugs, the War on Money Laundering, and subsequently, the War on Terror.
