Amazon Payments, Inc., is a wholly owned subsidiary of Amazon.com  that provides a means to process transactions online. Launched in 2007, Amazon Payments uses the consumer base of Amazon.com and focuses on giving users the same checkout experience available on Amazon.com.
Amazon Payments has several products for consumers, businesses, and developers.
Amazon Payments is a way for customers to purchase goods and services from US based websites using the payment methods in their Amazon.com accounts, such as their Visa or MasterCard. (Currently Amazon.com and Amazon Payments will not accept payment methods such as PayPal or Google Checkout.) At participating vendors, which include Patagonia and Jockey, users can check out using their Amazon account information without needing to re-enter credit card numbers or shipping addresses. Users can also check out with Amazon's 1 Click.
Other consumer products
- Amazon TextBuyIt is an SMS-based service which allows users to find items, check prices, or purchase items simply by sending a text message to "262966[clarification needed]" (AMAZON). Users can also text searches to "262966" and receive search results and prices quickly.
- Amazon WebPay is a free service to send or receive money using an e-mail address through the Amazon Payments web page.
- Amazon TextPayMe was a service similar to WebPay, except users can use SMS messages to complete the transaction. The premise behind the service was to allow users to pay each other instantly and securely, without having to carry change or remember IOUs. The service was deprecated in late 2011 and is no longer available.
Checkout by Amazon
Checkout by Amazon (CBA) is an e-commerce solution that allows US based web merchants to accept Amazon account information and use Amazon for payment processing. CBA can manage several aspects of the transaction including order processing, promotional discounts, shipping rates, sales tax calculation, and up-selling. Depending upon the needs of the merchant, CBA can be integrated into the merchant's systems with manual processing (through Seller Central) or through SOAP APIs or downloadable CSV files. CBA also claims to reduce bad debt because of Amazon's fraud detection capabilities.
Amazon Simple Pay
Amazon Simple Pay (ASP) is a set of payment-only products that allows US based web merchants to accept Amazon account information and use Amazon for payment-only processing. ASP differs from CBA in that ASP does not handle additional capabilities associated with order processing such as promotions, tax & shipping, and so on.
Amazon PayPhrase was a recent addition to Amazon Payments which allowed customers to check out by typing their PayPhrase and their PIN without having to enter any shipping or credit card information. It was accepted at Amazon.com as well as at certain retailers, including Buy.com and J&R Music and Computers. PayPhrase's claim of being additionally secure is controversial. Amazon PayPhrase was discontinued on February 20, 2012.
In September 22, 2010, Amazon published a security advisory  regarding a security flaw in its Amazon Payments SDKs. This flaw allows a malicious shopper to shop for free in web stores using those SDKs. Amazon mandated all web stores to upgrade to its new SDKs before Nov. 1, 2010. Amazon acknowledged security researcher Rui Wang for finding this bug. The detail of the flaw is documented in the paper "How to Shop for Free Online - Security Analysis of Cashier-as-a-Service Based Web Stores" by Rui Wang, Shuo Chen, XiaoFeng Wang, and Shaz Qadeer.
