Which term refers specifically to a small computing device used by employees to track work and accept payments?

The term that specifically refers to a small computing device used by employees to track work and accept payments is "handheld computer." Handheld computers, also known as handheld terminals or mobile devices, are designed to be portable and can easily fit in a user's hands. They often come equipped with touchscreens and various connectivity options, enabling users to input data, access information, and perform transactions directly from the device.

These devices are widely utilized in various industries for tasks such as inventory management, sales tracking, and point-of-sale transactions, allowing for a more efficient and mobile workflow. Their portability and ease of use make them particularly suitable for tasks that require quick access to information or the ability to execute transactions on the go.

Other types of computing devices mentioned, such as microcomputers and minicomputers, do not capture the mobile aspect inherent in handheld computers, while peripheral computers refer to devices that connect to a host computer but are not themselves standalone computing devices.
