The Leap Top-Up app is a convenient tool that allows users to manage their Leap Card, a contactless smart card used for public transportation in Ireland. With the app, users can easily check their card balance, top-up their card, and purchase or collect pre-paid tickets. The app is compatible with NFC-enabled Android smartphones, and users can simply hold their Leap Card to the back of their device to perform these actions. Some key features of the app include the ability to check the balance of any Leap Card, top-up instantly by selecting a value or entering a desired amount, purchase pre-paid tickets such as Dublin Bus Rambler and Bus Éireann Zonal tickets, and collect pre-paid tickets like Bus Éireann TaxSaver tickets or online purchases. Users can also view their transaction history, proximity to daily/weekly capping values, and receive receipts via email for top-ups or purchases made through the app. Additionally, the app allows users to save their payment details, view card information, access ticket information, and submit customer support queries. It's important to note that the Leap Top-Up app is only available on NFC-enabled Android devices running Android . or later. Some users may experience issues with the app if their NFC-enabled device does not support the required "NFC Read/Write" functions. Entry-level NFC devices that only support "NFC Card Emulation" may not be compatible with the app.
