Because when you are at a concert or at a park, you need more fun time rather then transaction time.
Often the food or ticket counters at concerts or parks do not accept credit cards due to various reasons. Also credit card transactions take some time depending on systems. Before you start your concert or entry to park, have a pre paid wristband to your convenience and then enter the premise.
System like this will give you hassle free transactions. Also for park/concert organizer will have to deal with less accounting time and giving them a transpartent picture of the amount people spent at the location.
Because at a concert or at a park, you need less access checking time for visitor and less human resource for organizer.
In many cases concerts and parks have either rides or areas that belong to different age groups or activity baesd areas. Sometimes tickets are also distributed according to differnt group interests. During the event, it is a cumbersome task to check the access for each visitor.
RFID based access control cards or wristbands make the job easy for visitors as well as organizers. Less human resource and more machines means centralized management, less cost and less chaos.
