LOGICAL JAVA CARD RUNTIME ENVIRONMENT

Techniques are disclosed for generating a message stream configured to indicate a source of the various messages within the message stream. In particular, the indicators identify which interface the messages were received at a terminal (e.g., of a mobile handset). The terminal receives messages on various interfaces, and separates the messages received via different interfaces with interface switch indicators within the message stream. In one embodiment, the smart card receives a message stream that includes sets of messages and interface switch indicators therein. The smart card delivers messages from the message stream to a single logical partition of the smart card up until an interface switch indicator is identified in the message stream. From that point, the smart card delivers messages from the message stream to a different logical partition of the smart card up until another interface switch indicator is identified in the message stream.
