What happens when I transfer between buses? Sometimes you’re going to take more than one bus to get where you’re going. You can use Snapper to transfer between buses to ensure you pay the best fare. Within a 30 minute window on any Metlink bus, just tag on and off each bus with your Snapper card and the fare is calculated automatically for the total zones travelled. How can I check it has worked? When you tag on an additional bus within the transfer criteria you should see the words “Transfer Applied” appear on the Snapper reader. You will also be able to view transfers in your online transaction history, or in the mobile app (Android or iOS). View the cost per zone when using Snapper on Metlink’s website.
