I held up my student ID card to the card reader, but it was marked absent.

If you have any questions about class attendance, please contact the instructor directly.

The contact information of the instructor can be found on the class page in the Scomb LMS.
Please check under "Related Links" on the left side of the relevant class page.
It will be listed as "Faculty Contact Information".

Also, if you have left your imprint before the time when you are allowed to imprint, you may be counted as absent.

Please make sure to check if the time is available for imprinting before imprinting.
