The Youtrip card is a multi-currency card that works like a wallet and allows access to a range of services and products that can be paid for with a credit card service terminal. The card works like a debit card and can be used immediately when it is top-up online.
The amount you save with a Youtrip card than a credit card is about 2-3% of the transaction fee charged by the credit card service and also the currency exchange rate.
If you are travelling, try both cards and check out the difference. I would recommend using the Youtrip card as the primary cashless mode.
