Google has released Checkout, a new payment service. Here's with Google Blog writes about it:
One cool feature of Google Checkout is that you can buy from stores with a single Google login – no more entering the same info each time you buy, and no more having to remember different usernames and passwords for each store. To help you find places to shop, you'll see a little icon on the Google.com ads of stores offering Google Checkout. It's an easy way to identify fast, secure places to shop when you search. And after you've placed your order, Google Checkout provides a purchase history where you can track your orders and shipping information in one place.
Because we see big benefits for shoppers as the service grows, our immediate priority is to help more online stores join Jockey, Starbucks Store, Levi's, Dockers, Buy.com, Timberland, Zales, and others to offer Checkout on their sites. To keep website integration simple, we've built a range of integration alternatives such as cut and paste buy buttons, pre-integrated ecommerce partner offerings, and an API that supports more advanced integration.
Google Checkout is cheaper for stores than PayPal and features benefits for AdWords users. You can check it out over here.
