There are a number of possibilities, the most common of which is:

1. It simply may be that you may not have enough funds in ewallet you are trying to use
2. The merchant doesn’t accept the card; some retailers are not CHIP and PIN enabled
3. To protect you from fraud all your card transactions must get real-time authorization. If their terminal isn’t online then it will decline your transaction. If the card continues to be declined, please contact our Client Support Team.
