If you get a mytaxi cab off the street, and want to pay with your mytaxi account, just ask the driver to do a "Hop-on-tour" or "Pay with mytaxi."

Now all the driver has to do is select the correct customer in his/her app and you will receive the request for payment on your device at the end of the journey.

Please ensure the amount in your app is correct. Then, simply slide to pay.
Note (not applicable to UK/IRE): Not all vehicles with advertising are also operated by mytaxi drivers. It is best to inquire with the driver as to whether he/she is a mytaxi driver.
