The doubt arose with a client who has maintenance crews going from site to site: "I want to know if the technician clocked in while standing at the client's site or from their living room sofa. Can I ask for their location when they clock in?". The short answer is yes, but with conditions. The long answer is that a person's location is personal data protected by Law 25.326, and using it incorrectly exposes you to a claim. Here I explain what the Argentine regulation allows you to do and where the line is that you shouldn't cross.
