For all of the progress the US has made in payment technology, it still clings to the past when it comes to credit card payments. You still have to sign for many in-person purchases, which is downright backwards in an era of chip-based cards and digital tokens. And the financial industry is finally ready to kiss them goodbye. As of later in April, four of the biggest credit card networks (AmEx, Discover, Mastercard and Visa) will no longer require signatures for these credit card transactions. It's up to retailers to decide whether or not to ditch handwritten approvals. As the New York Times noted, though, it's doubtful many retailers will keep up the tradition.
