Riders can request trips in the Uber app using Twint as a payment method to pay for their rides.
To add Twint as a payment method:
1. Select "Wallet" in the menu in your Uber app
2. Tap "Add Payment Method"
3. Tap "Twint", then "Enable"
4. Follow the prompts in your app.
To remove Twint, follow the steps above and select "Remove".
When adding Twint to your account, you may be required to authenticate yourself as the account holder, as a safety precaution from the service provider.
Once you have authenticated yourself, the payment method should be available directly on your Uber account.
Please keep in mind that some service providers have their own authentication method, which may result in the app directing you to another web browser or page.
If you would encounter any difficulties with the authentication process, please reach out to the service provider in question.
