The disclosed embodiments provide systems, methods, and techniques for managing transaction cards. User registration processes, order processes, and failure detection processes for a secure universal shopping cart are provided. Systems and methods may acquire identifiers. Systems and methods may also identify items associated with the identifiers. In addition, systems and methods may acquire a list of merchants that offer each item. Systems and methods may further determine, for each identifier, merchants based on user preferences. Even further, systems and methods may generate a payment token for each item. Systems and methods may then transmit the payment token for each item to its respective merchant.
