Opal NFC Reader for Android
This the only app in the store that allows you to read your opal card without having to log in. But the project is left half way through. You cannot even remove a card once it is added! Works for old cards only.
Waste of time. Uninstalled.
needs a lot of improvements but good to read the balance
