Visa is completely rehauling its online payment system to add more security. 9to5 Google reports today that Visa Checkout, a competitor to Paypal which integrated with the Google Pay digital wallet, is shutting down in 2020. The move isn't an entire surprise. Earlier this year, Visa and all the major credit card companies -- Mastercard, American Express and Discover -- announced they would unite and launch their own checkout button. It was discovered earlier this week that Google Pay no longer lists Visa Checkout.
