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 passed 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.
