A quick and easy way to check the balance on your Credibus card with your phone's NFC, just tap your card to check the balance.

Works on all Credibus cards in the Granada area (Youth, University etc..)

-Remember to read the card softly, do not tap it too fast or move it too roughly while the balance is being read.
-This app can only read the card's balance, you can recharge your card inside the buses themselves or in authorized points of sale.
