Credit cards can be denied for several reasons. The most common reason is that the bank processing the card does not permit online transactions for security reasons. You may contact your bank to enable your card to be eligible for online transactions. Another reason is that a piece of information may not match when the payment solution checks the verification of the card. In this instance contacting the credit card solution to determine why the card was not allowed to pass is the quickest way to solve the problem. Credit cards from all countries may not be accepted and your country must be located in their permitted list in order to use the credit card merchant account service.
    If you have previously entered your credit card when attempting to open a Paypal account, they will not accept the card unless it is used through the original Paypal account. The card cannot be used independently through Paypal outside of the account for security reasons.
