A minimum top-up value of S$20 is required to add money to your YouTrip account. This can be done simply through your YouTrip app with any Singapore Dollar based credit/debit card.
The maximum top-up amount is S$5,000, which is also the maximum limit your YouTrip wallet can have at any point in time regardless of the currency. If you exceed the maximum limit, the excess will automatically be refunded to the most recent card used to make top-ups to your account.
For example, if your wallet has S$100, US$100 (equivalent to about S$139.70), your maximum top-up amount will be S$4760.30.
