The card number is incorrect.
This error means that PayStand is declining the transaction because the card number is incorrect.
This indicates a problem with the information entered for the card. Double-check the credit card number, expiration date, and CVV. If you haven't already, also ensure that the card has been activated.
If you are entering the right card number and the system keeps on saying to correct the card/CVV number, then it means that your card is not acceptable this time or Paystand cannot charge your card at this time.
The payer must contact their card issuer for additional information. PayStand is unable to determine the cause of this message on behalf of the payer.
The payer can provide a new payment method.
