Daily Punch Cards?

Do any of you readers out there have any insight into Graham's question? 



I am in the process of restoring my time recorder and due to the fact that these are very well made it has been quite straight forward, mainly cabinet work due to the fact of how it was bolted to the wall.My question is about the time stamp?. I can  not see that it has anyway that it could change the position of the card on a daily basis so one card would register times over a week period.Is it possible the employer would issue a clocking in card for everyday?.

I look forward to any comments.

Thank you,
