No, with TapTapCap your contactless payment card or device is your ticket, so it’s one card or device per passenger.
Instead, you can tap your card or device to record a TapTapCap journey for yourself and then use the same card or device to purchase a ticket(s) for the other person. Please note that capping cannot be applied to paper tickets, so please take care to request the appropriate ticket. The driver will let you know when to tap your card and, if the transaction is approved, the ticket(s) will be printed.
