When the access control system is unable to automatically choose an access right for the client among those available, it will have to be selected manually.  This can happen when a client has two or more multipacks that are all valid for access at a given moment, therefore it will be necessary to select one, so that the system can proceed with the deduction of the credit required for access (as a matter of fact, this functionality only works for passes, i.e. multipacks with credit).

Please note that this option must be activated from the VAR portal: Cod. 10095 - Access control: enable multipack with same priority check 

Just click on the Browse button and the system will provide a list of the current subscriptions/multipacks of the customer.

Select an option and the system will let the user in.
