Technical Issue in ClassPad II fx-CP400: Lack of De

[Shahram50 Profile]

Hello everyone,

I would like to discuss an important technical limitation in the ClassPad II fx-CP400 that affects software development and security. Currently, there is no built-in command to retrieve the device's unique identifier (such as a serial number or device ID).

Why is this a problem?

Developers cannot implement software licensing for their programs.

There is no way to restrict software execution to specific devices.

Identifying different devices in academic or professional environments is difficult.


Suggested Solution:

I propose that Casio adds a command like GetDeviceID() in a future firmware update. This would allow developers to retrieve a unique identifier from the calculator, helping with security, licensing, and device differentiation.
