OV balance checker

The OV balance checker can check the balance of your Dutch OV-chipcard. Point your device's camera at the OV-chipcard and the app will show the card's balance: the app recognizes the card number and uses this to look up the balance at ov-chipkaart's website.
If the balance is not enough, press the €-button to order new balance for that card. You will be redirected to ov-chipkaart's website with the card's long number already filled in!
