Yes, you can use your YouTrip card for public transport after you've performed your first top-up on your YouTrip app.
To enable your card for public transport, please sign-up for the Mastercard® Account-Based Ticketing (ABT) function at https://abt.transitlink.com.sg
What is Account-Based Ticketing (ABT)?
ABT enables commuters to use their credit/ debit cards for contactless fare payments. Upon successfully registering your YouTrip card for ABT, public transport fares will be processed and charged to your YouTrip card.
ABT is a pilot programme between the Land Transport Authority (LTA) and Mastercard to introduce contactless payments on local trains and buses.
Activating the ABT function on your YouTrip card:
Once this is done, the activation process will take up to 3 working days to complete. Ensure that you've performed your first top-up or that there is sufficient balance in your YouTrip app before you start tapping at MRT and Bus gantries!
