There are 2 ways a passenger can contribute for the ride:
1. Wunder Wallet
The easiest way to contribute to your ride! Top-up your Wunder Wallet with a credit or debit card (any VISA or MasterCard is accepted) and you'll be ready to use the Wunder Wallet. At the end of the ride, just tap 'Use Wallet' and the funds will be automatically transferred.
If you haven't yet topped-up your Wallet, no worries, as you can still pay with cash. Make sure to give your contribution to the driver before you leave the car.
The driver will be able to see the mode of payment (cash or Wallet) in their ride history to keep track. When you pay via Wallet, you will have a list of your transactions on the 'My Wallet' screen but cash contributions won't be shown here.
