Attendance data format about zklibrary HOT 13 OPEN

The state maybe difference each device. Normally, we don't need the state. The state of check in and check out can be determined from the sequence of attendance at certain time intervals. You should compare it with other attendance at that time span, for example employee shifts.

My best practice, I get the attendance data and I save it into the database. I create a event trigger on the table on insert. If there is no attendance of the user at the time span, so the attendance will be considered as check in, else the attendance will be considered as check out.
To get the real check out, select the last attendance of the user at the time span. But if the is only one attendance of the user at the time span, check out is not exist.

@RahamSher were you able to differtentiate between check in and check out? If yes, then how?

from zklibrary.

The first check on the day is check in and the last check on the day is check out. So, at least user check twice in a day.

So is the checkin/checkout showing now?

In the Zkteco MB360 the check in and check out value is in position 66 and they are 2 characters.
