Fraud Prevention
Financial Peace of Mind
QNB Bank proudly offers round-the-clock fraud prevention services to all QNB Debit Card holders through automatic fraud monitoring, Visa® 3-D Secure for online shopping, and optional card management tools. We also provide monitoring to protect online banking sessions from fraudulent activity along with online and mobile banking alerts.

Debit Card Fraud Monitoring
A Fraud Center automatically monitors your QNB Debit Card transactions 24/7 to identify potential fraud. If potential fraud is detected, you will be contacted by SMS text, email, or phone and asked to verify whether the transaction was fraudulent or valid. You will NEVER be asked for your private personal information. You will only be asked to identify if you did or did not make a transaction with your QNB Debit Card.
Visa® 3-D Secure
QNB Bank provides a fraud protection service called Visa® 3-D Secure (3DS), that adds an additional layer of security for online shopping purchases made with your QNB Bank debit card.

How Visa® 3DS Works
The 3DS system is set up to look at suspicious patterns of transactions. The transaction can follow one of three paths:
- Green – low risk; the transaction is automatically approved
- Red – high risk identified; the transaction is denied
- Yellow – medium risk; the customer must complete a multi-factor authentication by receiving and entering a one-time passcode for the transaction.
Customers will be presented with the method they want to receive the one-time-passcode (OTP). Once selected, they will be sent to the customer's contact information on file at QNB Bank. The options include SMS text, email, or phone call. (Message and data rates may apply.)
Fraud Tip: QNB Bank representatives will never ask you for your passwords, passcodes, PINs, debit card numbers, or expiration date.
If the online purchase activity isn’t deemed suspicious through the 3DS system, it will be approved or denied through the normal Visa® and banking approval process. If 3DS rules are triggered, the cardholder will be asked to authenticate the transaction. Cardholders will receive a popup message with our bank logo in the upper left corner. Customers will have three attempts to authenticate themselves. If there are three failed attempts, the cardholder will be directed to contact the bank.
If no 3DS rules are triggered, or if a 3DS rule specifically allows the transaction, it is allowed. After passing through the 3DS system, the transaction is also evaluated by the Card Fraud Center, which may prompt another layer of validation. If the customer is registered in MyCardRules™, those self-established parameters would still apply.
Customers who experience a failed authentication may contact the Bank for additional support. Our Customer Service Center is available by phone at 215-538-5605 or 800-491-9070, by email at [email protected], or by utilizing the chat feature found on this website.

QNB Patrol
QNB Bank offers a fraud protection service, QNB Patrol, which detects potentially fraudulent online banking sessions in real-time.

How QNB Patrol Works
The system is set up to examine QNB Online Banking Users' typical login behavior and compare it to historical login activity and knowledge. If the login behavior falls into the category of "suspect," and the activity is considered high-risk, the system will require the User to provide additional authentication by receiving a Secure Access Code (SAC), a one-time numeric passcode before high-risk tasks can be completed.
How will a User be contacted when suspect activity is detected?
If QNB Patrol identifies the login activity as suspect and high-risk, it will require additional User validation. The SAC is sent to the User's contact information on file at QNB Bank. The options include SMS text or phone call*. TIP: It is vital that you keep your contact information up-to-date at QNB Bank.
*Message and data rates may apply.
What happens if QNB Patrol cannot validate the User's access?
If the system cannot validate the User or determines that the attempt to log into their online banking profile is fraudulent, the system will block the high-risk activity from being completed.
