Debit Card Monitoring

Extra security for your debit card.

In an effort to help protect your accounts, Nantucket Bank monitors all debit card transactions for suspicious activity. You may receive a phone call asking you to verify the details of your transaction if we notice something that looks unusual on your account. We will not ask you for your account or PIN numbers – you should never provide these to anyone who calls. If you receive a call, our representative will simply ask that you verify whether you used your debit card to make a particular transaction(s).

This extra confirmation is our way of helping to protect your MasterCard® Debit Card from theft or fraud. If you have questions, please call us at 508.228.0580.

While Nantucket Bank takes many precautions to protect your identity and bank accounts, there are numerous ways YOU can be proactive in guarding your personal information, too. Visit our Online Education Center to learn more.
