Is there a facility check-in/swipe system that integrates with an online scheduling system?

That is a special system that is possible, but would need to be set up by a locksmith and/or computer tech who possesses those skills and reps those types of products. I have seen some studios that have swipe systems that allow them to monitor who has been in and when and who can enter at specific times or time ranges. I believe they had different swipe cards as well. The owner had a master swipe card that would allow them to go in whenever they wished, the instructors had cards that only worked between certain hours, some patrons had cards that worked during business hours and some had special rates where their cards worked only during the later evening or slow volume times. If you haven’t already, you should begin contacting locksmiths. Keep asking until one of them can set you up or knows someone that can set you up.
