Attendances without start or end time or other ideas?

Hello,

I would like to implement my own time recording via my own terminals using the API.
If I have understood it correctly, the employees have to select ‘come’, “go”, ‘break start’, break end" at the terminal.
I find it easier if the employees just hold the chip to the terminal and the logic happens internally. I.e.

scan: come in
scan: leaving or pause
scan: pause end
scan: leaving.

As I currently have to specify a mandatory start time for attendances and absences, it cannot be implemented as I had planned.

Perhaps I have overlooked something and it can still be implemented with the current API as I would like?

Thanks and regard. Walter.
