Protect Your Business from
Merchant Account Fraud


The security of your credit card processing systems and your customers’ financial data is integral to the health of your business. These systems are increasingly under attack from cybercriminals who use sophisticated methods to access valuable account information. It’s critical to be aware of any threats to your business and have measures in place to deter fraudsters.


Accepting payments is the lifeline of your business.

In the last year 37% of businesses have been impacted by fraud.

Here are some ways you can combat it.

If you accept payments in person:

Use the EMV chip.

When prompted, encourage your customers to enter their PIN.

If you’re accepting payments virtually or online, review and consider all fraud filter settings including, but not limited to:



Velocity Thresholds

How Cybercriminals Are Attacking

Taking advantage of vulnerabilities in your system’s security, fraudsters will hack merchant accounts to run authorizations to test the validity of card details they have stolen or purchased on the dark web. These fraudulent authorizations can result in an onslaught of fees and charge-back risks to your business.

Best Practices at the Credit Card Terminal

  • Use Address Verification (AVS) during each sale if the card is not present.
  • Enter the three- or four-digit Card Verification Value (CVV) whenever possible.
  • Swipe or use the EMV chip as much as possible.
