C. It supports the control of the number of people who enter the station by swiping the card and checking the ticket according to the parameters set by the system.
D. Deal with the abnormal situation of swiping card to check tickets separately, including:
●Exit from the gate station
The system sets parameters such as time control, default deduction station, deduction method (one way or round trip) and billing method (free or station ticket). The outbound gate judges the inbound and outbound check-in time interval. If the time control parameter is exceeded, the deduction will be made according to the default deduction station and deduction method parameter settings; otherwise, it will be free (clear the current gate record) or deduct the station ticket .
●Outbound from non-inbound station
The system sets parameters such as time control, default deduction station, deduction method (one way or round trip). The outbound gate judges the time interval of inbound and outbound ticket checking. If the time control parameter is exceeded, the default deduction station and deduction method parameter settings will be deducted.
●The card is damaged when entering the station or swiping the card normally when entering the station, and the card is damaged when leaving the station
Passengers go to the fast pass card service window for bad card registration. The operator performs the bad card registration operation in the system and prints the bad card voucher, and the bad card is recovered. Passengers can take the bad card voucher to the service window of the fast pass card to change the card after 2 days.
