Combicard transaction method and system having an application parameter update mechanism

摘要

Systems, methods and IC card devices are described for updating parameters such as unblocking or blocking or re-blocking an application on an IC card device whereby an integrated circuit card device gets issued with one or more active applications and optionally one or more dormant applications. Post issuance, triggered by a cardholder action when using a primary application, the issuer will send a command, e.g. in the form of a script to the card that will update parameters of another application, e.g. to ‘wake up’ the or each dormant application. An on-card mechanism is provided for the deblocking of the dormant application while the primary application is active. For any further transactions performed with the card, the cardholder will be offered a choice between the unblocked applications on the card. Optionally the oncard mechanism can also block or re-block an application or perform other actions.
