Additional Security for Debit Card Users – We’ve added an additional layer of security to protect your debit card use from fraudulent activity. As a result, if you make a signature-based debit card purchase, you may be told that your card is not working. Please enter your Personal Identification Number (PIN) and the transaction should be successfully processed. If you have any questions, please give us a call. We apologize for any inconvenience that this may cause.
