Abstract

An online electronic wallet system and method provide secure storage and transmission of payment instrument information for use in completing online purchases initiated from a client device. A payment instrument's verification code is stored in an encrypted form in local storage on a client device and retrieved and re-encrypted along with other payment instrument information stored on the system using a merchant-specific key. An API library is used to integrate the online electronic wallet system with a registered merchant's purchase flow, including the ability to ensure receipt of an electronic receipt prior to communicating payment instrument information to a merchant server.
