Which of the following electronic devices is authorized within the SAPF and similar areas?

Electronic calculators are authorized within the Special Access Program Facility (SAPF) and similar areas primarily due to their limited functionality and lack of advanced communication capabilities. Unlike smartphones, laptops, and tablets, electronic calculators are designed for basic mathematical computations and do not have the capability to connect to networks, access the internet, or handle sensitive data in a manner that would risk security breaches. This makes them acceptable for use in environments where strict security measures are in place to protect sensitive information. Their simplicity and focus on specific tasks mitigate the risks associated with more sophisticated electronic devices that could potentially introduce vulnerabilities.
