Ian Kar, writing for Quartz: Over the last year or so in the U.S., a lot of the plastic credit cards we carry around every day have been replaced by new one with chips embedded in them. The chips are supposed to make your credit and debit cards more secure -- a good thing! -- but there's one little secret no one wants to admit: The U.S.'s transition to chip cards has been an utter disaster. They're confusing to use, painstakingly slow, less secure than the alternatives, and aren't even the best solution for consumers. If you've shopped in a store and used a credit card, you've noticed the change. Retailers have likely asked you to insert the chip into the card reader, instead of swiping. But reading the chip seems to take much longer than just swiping. And on top of that, even though many retailers now have chip reading machines, some of them ask us just the opposite -- they say not to insert the card, and just swipe. It seems like there's no rhyme or reason to the whole thing.
