Square, a company that supplies point of sale (POS) systems to small businesses that allow for credit card processing, has been down all day Thursday, affecting users in the U.S., Canada, United Kingdom, Australia, Japan, France, and Spain. Square is one of the largest suppliers of POS systems to all kinds of businesses, like restaurants, salons, tattoo parlors, boutiques, and much more. According to the website, Square is "Trusted by millions of businesses worldwide."

Without the ability to process credit cards, many businesses have reported turning away customers who don't have cash—or taking an enormous risk and writing down credit card information to process later, not knowing if the card will go through. Despite Square's customers losing thousands of dollars per hour, their customer service line was shut down and goes directly to a voice message that says the service line is unavailable.
