Checking out or renewing items in the self check
After a staff user has logged into the self check interface, the interface
is ready for patrons to log in and check out or renew items.
- 
The patron logs in by entering either their patron barcode or their user name.
- 
The patron enters the barcode for each item. If the patron types the barcode,
  they need to press the <Enter>key to check out the item. The item details,
  including due date, appear below the barcode field.
- 
When the patron is finished, they can click Logout if they want a receipt
  for their items, or Logout (no receipt) if they prefer no receipt.
