This feature is designed primarily for night clubs offering a guest list where tickets are only valid up until a certain time. For example, let’s say you run a night club and you are offering free guest list entry before 10pm. You can create a guest list ticket widget that allows your guests to register and even download actual barcoded tickets. These tickets will scan as valid across all methods of scanning (smartphone apps, professional scanners, box office, etc.) up until the cut off time. After that time, all of the guest list tickets will be voided and will no longer be valid for admission.
