An approach to managing stored-value data objects, such as electronic tickets, comprises secure systems and procedures for ticket issuing, storage, and redemption. With these systems and procedures in place, stored-value data objects may be securely transferred to remote systems, such as a user's personal electronic device, for subsequent secure redemption, thus allowing the user to gain access to the desired goods or service upon redeeming the data object. Techniques provide secure delivery of the requested data object to the requesting device, and provide secure redemption and disposal of the data object. Ticket issuing systems may be Internet-accessible systems, and users may purchase and redeem tickets using mobile terminals or other devices adapted for wireless communication. Standardized WPKI and Internet access procedures may be employed in ticket issuance and redemption. Techniques further provide temporary and rapid verification data objects useful where rapid ticket verification is essential, such as mass transit systems. |
