When you come to the lab, bring your UNL ID card. You need to check in at the desk in the center of the lab, and, when you leave, you check out. The attendant at the desk swipes your card through the card reader to check you in and out. The transaction will be displayed on the computer. If your registration has changed, let us know so that we can update the information on our computer. Your instructor will receive a weekly lab-attendance report.
