How ride fares are withdrawn
The total cost of your ride is reserved immediately after you are dropped off at your destination. In some cases, part of the total cost is reserved at various points during your ride. The money is withdrawn within 24 hours after the funds are reserved.
If you don't have enough funds left on your card to pay for your ride, the amount due will be withdrawn automatically when you add funds to it. Your total may be debited all at once or in several parts over the course of one year starting from the moment when the system first failed to debit the full amount for your ride.
