Remember V.me, Visa's big attempt at conquering the online payment space? You'll be forgiven if you don't -- it quickly fizzled out, in part because it was a digital wallet that sometimes made shopping more complicated. The company may have learned its lesson, though. It just launched Checkout, a considerably simpler approach to e-commerce. The focus here is purely on getting through the checkout process as quickly as possible. Once you've put in the details of supported credit or debit cards (including non-Visa cards), you just have to log in to complete a purchase, whether it's on a website, Android or iOS. There's no in-between wallet, and you won't get kicked over to another page just to wrap up a transaction.
