Process Cont. 

After getting input from our professors and peers we realized that a lock and gate would still be restricting and make it harder to create a sense of community. We, therefore, chose to shift our focus and instead have it be an opt-in system where chaperones could get an RFID tag if they wanted to. To still answer the problem of security our team considered possibly running background checks on everyone that wants to be a part of the P.A.S.S. system but later realized that this might also be restricting to reformed ex-convicts for example. Thus our final idea was simply to have a parent scan their ID and indicate the number of children they had. A hurdle we faced was getting the RFID tag to work, which is why in our demo we used buttons instead to mimic the action of going in and out of the park, but it still got the point across of parents opting in or out.
