A. Merchants sometimes call this the “No Monkey” or “No Money”. This response will flash on the pin pad after the debit card has been swiped through the terminal. The pin pad will go back to dashes across the pin pad. This means the pin pad has lost it’s encryption and needs to be replaced. Q. Declines are received on all debit card sales. A. Call a Customer Service representative. Additional troubleshooting must be completed. This could indicate a compatibility problem between the PIN pad and the credit card terminal, or it may indicate that the PIN pad will require encryption. Q. When a debit card is processed the response “Waiting for answer” is received. A. Innovative Merchant Solutions’ debit card program uses the same authorization telephone numbers as those that are used for Visa and MasterCard transactions. Normal processing of Visa and MasterCard transactions would indicate that the debit card system could be busy so the transaction should be attempted again in a few moments.
