Stämpelklockor

Stämpelklockor, also known as time clocks or punch clocks, are devices used by employers to record the arrival and departure times of employees. Historically, these machines used a paper card or ticket that an employee would insert into the machine. The machine would then print the date and time onto the card, creating a physical record of the employee's working hours. This system was a common method for calculating wages, particularly for hourly workers.

Modern stämpelklockor have largely moved away from physical cards. Many systems are now electronic or digital, utilizing various technologies such as key cards, biometric scanners (fingerprint or facial recognition), or even computer software. Employees interact with these systems by presenting their credential or using their biometric data, which registers their clock-in and clock-out times in a digital database. This digital data can then be used for payroll processing and workforce management.

The primary purpose of a stämpelklocka is to ensure accurate tracking of employee work time, which helps prevent payroll errors and provides a clear record of attendance. They are also used to monitor punctuality and adherence to work schedules. While the technology has evolved significantly, the fundamental function of recording work time remains the same, serving as a tool for both employers and employees to manage and verify working hours.
