MasterCard Debit Cards

Frontier State Bank is proud to offer EMV chip-enabled MasterCard debit cards. Our chip-enabled debit card is the fast, safe and convenient way to make purchases anywhere MasterCard® debit is accepted as well as access to your cash when you need it, anywhere in the country. The amount of your purchase is deducted from your checking account. A Frontier State Bank debit card gives you the latest in security by generating a unique code every time you use it at chip-enabled terminals, keeping your account number protected from counterfeiting. When using your debit card, here are some tips for safety, security, and efficiency:

  • Never reveal your PIN.
  • Memorize your PIN; never write it down.
  • To change your PIN, please call MasterCard customer service at 1-800-290-7893 (on or after May 25, 2023).
  • When in doubt if a merchant has a chip-enabled terminal - swipe your card first.
  • When using your card in an ATM, read the screen and follow directions. Some ATMs require you leave your card inserted throughout the entire transaction while others do not.
  • Setting up our free online banking and mobile banking app, allows you to manage your debit cards, get alerts on purchases, track receipts, activate or deactivate or report lost/stolen cards.   All within our mobile app or online banking portal.
