Abstract
An electronic controller for conducting trusted lightweight e-commerce transactions. A trusted transactional cache and the associated transactional protocol allow e-commerce transactions to be committed to a remote server extremely quickly and with little network overhead. The end-to-end transactions are completed is just a few seconds or less. The invention operates equally well on robust private networks as on unpredictable Internet or wireless networks. The transaction is automatically completed following a temporary communication failure with the central site or following a temporary local controller failure. The invention can advantageously be used in embedded Internet products such as fixed or mobile Internet kiosks, transactional terminals, and Internet Appliances.
