Upon approaching the self-checkout station, you will be prompted to swipe your Cat Card using the reader on the right side of the monitor. If you wish to use the self-checkout in any language other than english, you can switch languages before swiping your card. 
After swiping your Cat Card, you can begin scanning barcodes. Barcodes are located on the front-right cover of Davidson's library books. To scan a book's barcode, you do not need to pick up the scanner. Simply place the barcode under the red light emitted by the scanner. If the barcode is not read, you can pick up the scanner and aim it by hand. This is demonstrated in the picture below.

After you have scanned all your books, click "done."

You are now checked out. After using the self-checkout station, you will receive an email from the Library Circulation Office confirming your checkout.
