This patent describes a method for buying an item online using only a single action. When a user views an item (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1), a client system (like your web browser) displays information about it. With just one click (Claim 3) or a single sound (Claim 4), the client system sends a request to a server system to order the item, along with an identifier for the purchaser (Claim 1). The server then uses this identifier to retrieve previously stored information, like payment and shipping details, to generate and fulfill the order (Claim 1). This process happens without needing to add the item to a shopping cart first, allowing for instant purchases. For example, if you're logged into Amazon and click a 'Buy Now' button, the system uses your stored address and credit card to complete the purchase immediately.
