    摘要： In a multiple application card system including an IC card comprising a microprocessor, a read-only memory, a random access memory and an electronically erasable programmable read only memory, a system for controlling access to one or more sets of programming instructions embedded in said read-only memory comprising means for storing on said IC card for at least one application loaded onto said card at least one access flag having a value indicating whether or not access by the at least one application to the at least one set of programming instructions shall be granted and means dependent on said value for allowing access to one or more sets of programming instructions.

    摘要： Secure establishment of a key associated with a first facility identifier is facilitated. The key is shared between a device and an operator of a first facility, via a public key management infrastructure of a payment system operating according to the payment standard, during a first transaction, substantially in accordance with the payment standard, between the device and the first facility. Controlling access to a first facility is facilitated, via the device, using the key associated with the first facility identifier, substantially without reference to an issuer of the device and substantially without use of asymmetric keys of the device, during a plurality of subsequent transactions, substantially in accordance with the payment standard, between the device and the first facility. The steps can be repeated for a number of different facilities, such as different transit systems, with appropriate rules to address a situation where the device has a limited storage capacity for keys of different transit operators.
