Currently when you define a membership you can select how many admissions in a time period (very good for preventing double taps). However we have a DIF instructor who does classes back to back and the classes are 45 minutes. This means if someone wants to take both classes, they cannot scan in for the second class until after the second class has started, or we manually enter them. If the 'admit every X hours' would allow .5 hr increments, they could use the system.
