In order to analyze the situation and determine whether a biometric system is suitable for recording working hours, it is necessary to see if the principle of data quality is met, since personal data can only be used if they are appropriate, relevant and not excessive, and this will mean assessing in each case the necessity and proportionality of the data processed, and also whether the purpose sought could be achieved in some other less intrusive way.
Therefore, in order to evaluate the proportionality of a given biometric system for recording working hours, it would have to pass the judgments of suitability, necessity and proportionality in the strict sense.
It should also be noted that it could be in contradiction with what the Data Protection Regulation says, which qualifies biometric data as a special category, and therefore has greater protection and more requirements are required to be used.
What is clear is that each case may be different, therefore it will also be necessary to analyze the affected group, the area in which the system for processing biometric data is to be implemented, the volume of personal data processed, the objective pursued, and finally the suitability of the proposed solution.
In contrast, there are systems such as Timenet, which strictly comply with current regulations, and which do not pose any type of controversy because they do not use biometric data, since it is a multi-platform system for presence control, marking, recording of the working day and time control for the company.
With a single working hours control application you will be able to centrally see the entries and exits of workers and the place of marking, have the record of the day available for correct compliance with the law and control the time dedicated to projects to optimize the company's human and physical resources.
