Terminal, terminal system, and non-transitory computer-readable medium for updating a terminal using multiple management devices

A terminal system, comprising:

• a terminal;
• a terminal management device configured to manage information of the terminal;
• and
• an update management device configured to manage an update of a program of the terminal, the update management device being different than the terminal management device, wherein
• the terminal includes:
• a transmitter configured to transmit a request to the terminal management device to determine whether or not the terminal is allowed to execute the update of the program;
• circuitry configured to, in response to receiving, from the terminal a management device, information indicating that the terminal is allowed to execute the update of the program, determine, using a table associating each of a plurality of terminal types with a respective power supply confirmation necessity indication, whether or not it is necessary to confirm that the terminal is connected to a power supply, and when it is determined that it is not necessary to confirm that the terminal is connected to the power supply, acquire an update program from the update management device and execute the update program received from the update management device.

A non-transitory computer-readable medium comprising computer readable program codes, performed by a terminal connected to a terminal management device and an update management device, the program codes when executed causing the terminal to execute:

• requesting the terminal management device to determine whether or not the terminal is allowed to execute an update of a program;
• in response to receiving, from the terminal management device, information indicating that the terminal is allowed to execute the update of the program, determine, using a table associating each of a plurality of terminal types with a respective power supply confirmation necessity indication, whether or not it is necessary to confirm that the terminal is connected to a power supply, and when it is determined that it is not necessary to confirm that the terminal is connected to the power supply, acquiring an update program from the update management device;
• and
• executing the update program received from the update management device.
