Mastercard Debit/Credit

Your debit Mastercard (debit card) is linked to your checking account for convenience of POS (Point of Sale) purchases and ATM usage. All purchases are deducted directly from your checking account. You have the option of using your debit Mastercard either as debit transaction with your exclusive PIN (Personal Identification Number), or as a credit transaction with your signature – anywhere Mastercard is accepted.

We encourage our members to use the signature-based Mastercard credit option for protection from fraud.

Remember – if you are planning to travel out of the country or to another state(s) for a period of time and use your debit Mastercard, contact Third Coast Federal Credit Union member services to let us know, and we can ensure that your foreign transactions are not blocked.
