There are different ways to use a real id cards. The identity card created by your company for its own use can control individual access to everything from employee areas to special lounges. If you know the employees, a picture is used as optional. Your presence is not necessary if the card features machine-readable identification. An employee can easily swipe her ID at a scanner for access to restricted employee areas. The picture is also not required to a customer who uses the identity card to get transferable privileges, such as a discount on purchases. If additional benefits are only due to the cardholder, such as entry to an over-21 lounge or if there is no availability of scanners so then a picture ID must be verified by you or an authorized employee.
