Visa Checkout has been a payment option on some sites since 2013, when it first launched we saw a lot of promotions pushing the payment solution but that has slowly dried up. In 2017 Visa checkout was added as an option in Google Pay (called Android Pay) but 9to5 Google noticed that Visa Checkout was removed from the support account & services area of Google Pay support. It turns out that Visa Checkout will be shutting down sometime in 2020.
