Abstract
A near field communication (NFC)-enabled client device includes one or more computer-readable storage media and an NFC interface component operational in a card emulation mode of an NFC protocol. The client device also includes an application for performing a transaction using the NFC protocol. The application is stored on the one or more computer-readable storage media. Programming logic is configured to receive and store a state object (e.g., a cookie) provided by a security authority using the NFC protocol when performing a transaction using the application. The state object includes an identifier, data payload and a public key associated with the security authority. The programming logic is also configured to transmit the state object to the security authority upon receiving an HTTP operation identifying the state object.
