If you have an NFC-enabled Android phone or iPhone 7 and above, you can check your balance with the Leap Top-up App. Just hold your TFI Leap Card to the back of your phone.
You can also view your travel credit balance online as well as previous transactions on your card.
(It can take up to 24 hours for transactions to appear on your online account)
You can also view your balance by asking for a balance enquiry at any TFI Leap Card payzone agent or by placing your card in the card pocket at any Luas/DART/Commuter Rail ticket machine and follow instructions on the ticket vending machine screen.
