Debit Card Fraud Monitoring

At Commerce Bank, safeguarding your account is vital. We offer state-of-the-art card monitoring to further enhance your account security and peace of mind.

Here are a few facts about this service:

  • Our Debit Card Fraud Monitoring tool reviews your normal card usage to determine abnormal or unusual account activity.
  • Combined with up-to-date industry fraud information, our monitoring tool will then evaluate each of your transactions.
  • If any transaction is considered out of the norm or risky, the automated service will contact you to assist us in verifying your transaction.
  • Confirm the transaction, and no further action is necessary.
  • If you indicate that you did not authorize the transaction, your card will immediately be blocked to prevent further fraud.
  • In cases when the automated system cannot reach you, it will leave a message.  Your card may temporarily be blocked until you have the opportunity to return the call.
  • We encourage you to contact our Customer Response Center at (800) 698-BANK (2265) should you question the validity of the automated call or any transactions posted to your account.
