US Patent 11397942 Online interaction security technology

Typically, online transactions, such as online purchases of products or services require entering sensitive transaction information into a third-party web browser or application. This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online transactions without entering any sensitive transaction information into a third-party system. Vendor websites may be configured to generate a unique code identifying the vendor offering the product/service, the product/service and price of the product/service. The smart card includes a keypad for entering the unique code and completing payment for the desired product/service. The smart card will include a microprocessor and wireless interface. The wireless interface provides wireless communication capabilities and the ability to initiate online payments based on information captured by the keypad.
