Amazon has introduced two new payment systems for merchants and consumers which brings it into a market dominated by PayPal.
Checkout is aimed at online merchants who want a pre-packaged payment system, including tools for managing delivery charges, VAT, promotions and special offers. It features Amazon's One-click option for rapid payment.
Simple Pay is aimed at consumers who want to use their Amazon account to make purchases on other retailers' websites.
Google introduced a similar system for merchants and consumers in 2006, also called Checkout, but it has not found favour with online retailers.
Auction giant eBay, which owns PayPal, has prevented consumers from using the Google system.Also see our eBay feature, eBay: Friend or FoeAlso see our story Ex-eBay sellers offer bang for your buck
