What happened with the chip card transition in the U.S.?

As the U.S. continues to transition to chip cards instead of the old magnetic strip-only cards, one thing is clear, wrote QZ contributor Ian Kar: the whole thing has been a disaster. The new technoogy is less secure, slower and confusing — and has brought heartache to the American public more than anything else.

"'Can you put your card in the chip reader please' ya hold on let me cancel my plans for the rest of the day," Instagram user beigecardigan joked on Instagram.

"Almost everyone involved — banks, credit-card companies, retailers and merchants, payment processors, terminal manufacturers — have been focused on their own bottom lines, rather than the impact their decisions will have on customers," Kar wrote. "And that’s created a maelstrom of incompetence."

Perhaps mobile wallet systems like Apple Pay will gain popularity and swoop in to save us all.
