Amazon.com has introduced “Checkout by Amazon” (CBA) that allows people with accounts to make purchases on third-party sites using their Amazon account credentials without having to leave the merchant’s site.

Amazon says by streamlining the checkout process for customers that it reduces the potential for shopping car abandonment for merchants.

The company says in the past when using other payment methods, users would leave a merchant’s site after clicking the checkout button, leading to an often confusing redirection.

“These enhancements to Checkout by Amazon reflect the feedback we’ve received from merchants who want to offer Amazon.com customers the convenience of using their account information with a more streamlined buying experience,” said Baris Cetinok, General Manager of Amazon Payments.
