Debit Card Tips

  • To avoid a transaction charge anytime you have an option of entering debit or credit, choose credit and sign your receipt. Entering your PIN will result in a transaction charge.*
  • If you have a loan payment at Sentinel Federal Credit Union that is past due, your Debit Card transaction may be denied.
  • Opt-in to add overdraft services to cover your ATM and every day debit card transactions – saving you embarrassment and the extra hassles in your already busy day.

Debit Card Notice

*We have learned that some merchants (for example, Walmart and Sam’s Club) may require their customers that pay with a Debit Card to use the debit option and enter a PIN instead of allowing the customer to choose credit and sign for their purchases. Unfortunately, we have no control over this decision by the merchants.
