IMPROVEMENTS OF SUBSCRIBER IDENTITY MODULE (SIM) ACCESS PROFILE (SAP)

Systems and methods for the subscriber identity module (SIM) access profile (SAP) over Bluetooth. In one embodiment, intermediate responses from a SIM card containing procedure bytes are not transmitted to the client, but rather the appropriate response is generated by the server and sent to the SIM card. In another embodiment, the client groups together multiple command APDUs (Application Protocol Data Unit) into one message before sending out to the server, and the message may also contain parameters indicating various actions to be taken by the server in case an error is generated. In another embodiment, the client instructs the server to perform poling of the SIM card in an autonomous manner for any proactive data. Embodiments are not limited to a SIM card, and are applicable to other types of smart cards, such as an UICC (Universal Integrated Circuit Card).
