Amazon Payments, an company, has streamlined the customer checkout experience with Checkout by Amazon (CBA).

CBA has been designed to enable account holders to making purchases on the merchant’s site using their account credentials without leaving the merchant’s site.

Customers can now access their Amazon address book and payment methods directly on a merchant's site. This means fewer steps to checkout, reducing the potential for shopping cart abandonment for merchants.

In the past when using alternative payments solutions, consumers would leave a merchant's site right after clicking the checkout button, a confusing process known as redirection.

"These enhancements to Checkout by Amazon reflect the feedback we've received from merchants who want to offer customers the convenience of using their account information with a more streamlined buying experience," Baris Cetinok, general manager of Amazon Payments, said.

CBA's tighter integration with merchant sites also means a substantial reduction in implementation time. E-commerce platform provider Demandware is enabling integration with Checkout by Amazon.

"We've found that CBA makes integration up to 60% faster than before. CBA now also supports all of a merchant's promotions, tax rules and shipping settings automatically,” Scott Todaro, senior director, Product Strategy, Demandware, said.
