Communication terminal apparatus, external storage medium, information processing system, one or more non-transitory computer-readable storage media, and method

An external storage medium configured to be detachably attached to a slot of a first communication terminal apparatus communicable with a server, comprising:

• a memory having stored therein at least first data;
• a terminal configured to be electrically connected to the first communication terminal apparatus when the external storage medium is attached to the slot of the first communication terminal apparatus;
• and
• a controller configured to:
• establish a session for communicating with the first communication terminal apparatus, in response to receiving a predetermined signal via the terminal;
• transmit the first data to the first communication terminal apparatus that acquires a first application associated with the first data from the server based on the first data from the external storage medium, while the session with the first communication terminal apparatus is established;
• and
• transmit the first data stored in the memory to the first communication terminal apparatus, when the first communication terminal apparatus executes the first application, in a state where the session with the first communication terminal apparatus storing the first application acquired from the server is established.

An information processing system comprising a communication terminal apparatus capable of communicating with a server, and a first external storage medium detachably attached to the communication terminal apparatus, wherein

• the first external storage medium is configured to store first data without storing a first application therein,
• the communication terminal apparatus comprises:
• at least one memory;
• a slot configured to detachably receive a first external storage medium;
• and
• at least one processor configured to:
• receive the first data from the first external storage medium attached to the slot,
• acquire, from the server, the first application corresponding to the first data and store the first application in the memory, when the first external storage medium is attached to the slot, and
• execute the first application stored in the memory, while the first external storage medium is attached to the slot, and not execute the first application stored in the memory, when the first external storage medium is not attached to the slot.

One or more non-transitory computer-readable storage media having stored therein instructions that cause at least one processor of a communication terminal apparatus, which includes at least one memory and a slot configured to detachably receive a first external storage medium, to perform operations comprising:

• determining whether the first external storage medium is attached to the slot;
• acquiring first data from the first external storage medium attached to the slot;
• acquiring, from a server, a first application corresponding to the first data, and storing the first application in the memory, in response to determining that the first external storage medium is attached to the slot;
• and
• executing the first application stored in the memory, in response to determining that the first external storage medium is attached to the slot.

A method for executing an application in a communication terminal apparatus including at least one memory, and a slot configured to detachably receive a first external storage medium, the method comprising:

• determining whether the first external storage medium is attached to the slot;
• acquiring first data from the first external storage medium attached to the slot;
• acquiring, from a server, a first application corresponding to the first data, and storing the first application in the memory, in response to determining that the first external storage medium is attached to the slot;
• and
• executing the first application stored in the memory in response to determining that the first external storage medium is attached to the slot.
