At this time, Grover doesn't offer an overdraft service for the Grover Card. Your account might show a negative balance for one of the following reasons:

  • You made an offline payment that had to be authorized later (for example, on an airplane)

  • Changes in the exchange rate during the time between a transaction and its authorization

  • If your Grover Card is showing a negative balance, please deposit money into your account to cover the balance.
