Exculsive iff app tickets

Single tickets
You can now also bulk purchase 10 Adult single journeys for £15.50!  Valid for any adult single journey on all services within Cardiff and between Cardiff and Old St. Mellons on route 30 and between Cardiff and Ty Verlon/Barry Docks Link Road. Simply purchase in advance and then activate just before you board.  Once activated the ticket is only valid for 30 minutes - so you will need to show your driver within 30 minutes of activation.

Day tickets
We've introduced a new bundle of 3 day tickets for £9.99 on the iff app – saving you nearly 10% compared to buying them individually.  Just like the 10 single ticket bundle, the 'easy three' will stay on your phone until use – with no expiry date.  This is ideal if you are working a few days per week or only travel every now and again.

This ticket is valid for travel within the Cardiff fare zone (Cardiff, Penarth, Sully, Dinas Powys, Llandough and to/from Newport), and each day is activated separately so use your day tickets whenever you wish to travel.

How to use your iff app... 

Download the 'iff app' on your mobile device.  Search 'Cardiff Bus' in your app store. The app is available for Android and iOS devices and is free to download.


Add your payment method. 

Pay with your debit/credit card or through Barclays Pingit.
Your card details are stored securely, and it saves needing to have the right

change when you get on the bus.

Pick your ticket.

Choose from day or week tickets.

Add them to your basket then proceed to the secure payment.

You can also choose when your ticket starts - it can be for travel today, tomorrow, or next week.



Show the driver the ticket on your screen.

The ticket is displayed on your phone's screen - you'll need to show this to the driver every time you get on.

The time that's left before your ticket expires is also shown here.

If you're unable to show a valid ticket on your phone, e.g. if your battery is flat,
you will need to buy a ticket for that journey from the driver.

If your phone loses signal or has poor coverage, you can still activate and
use your ticket.
