We work hard to ensure that you are protected from fraud when you accept credit card payments, but there are ways that you as a business can be vigilant too. Here are some simple tips on how to spot and avoid possible fraud.
Prevent credit card fraud

Prevent credit card fraud (8:39)

 

Some signs that a transaction could be fraudulent

  • First-time shopper.
  • Larger-than-normal orders. Because stolen cards have a limited life span, maximizing the value of each transaction processed is important to the crook.
  • Orders that include several of the same items.
  • Orders made up of "big-ticket" items.
  • "Rush" or "overnight" orders.
  • Orders from Internet addresses making use of free email services.
  • "Ship to" address is an international address. Address Verification Service cannot validate most non-U.S. addresses.
  • Watch for multiple purchases on the same day.
  • Orders shipped to a single address but made on multiple cards.
  • Multiple transactions on one card or similar cards with a single billing address but multiple shipping address.

Additional security for online businesses

If you accept payments online here are some standard computer industry security best practices.
  • Install a Firewall. Firewalls are special servers that monitor the activity of external connections, primarily the Internet, to an internal network of servers. Firewalls help to eliminate the threat of any undetected external activity, and safeguard your network and connections from outside vulnerabilities.
  • Store all sensitive or confidential information separate from Web servers. Customer information in particular, such as credit card numbers, should be stored in a secure database on a server that is not connected to the Internet. It is also a good idea to encrypt all stored information.
  • Use good Anti-virus software and update it regularly. Anti-virus software is another important way to protect your network and computer systems from outside vulnerabilities. This software should be updated on a regular basis.
  • Regularly download and install security updates. For server and individual computer operating system software, you can optimize performance and systems protection by maintaining compatibility with service and security updates. Remember also to reinstall service and security updates when reinstalling software.
  • Avoid file sharing. Share access to network drives and individual computers only with needed, trustworthy users. Especially avoid sharing access to files that store passwords and other confidential or sensitive information.
  • Avoid idle Internet connections. Disconnect when you are finished using the Internet. This also eliminates the possibility of undetected outside vulnerabilities.
  • Support Verified by Visa® and MasterCard® SecurecodeTM. Businesses who use Verified by Visa are protected from fraud-related chargebacks on all personal Visa cards — credit or debit, domestic or international — whether or not the issuer or cardholder is participating in Verified by Visa (exceptions apply). Businesses who participate in MasterCard Securecode are protected from fraud related chargebacks when both the issuer and cardholder do participate in MasterCard Securecode and the transaction is fully authenticated.
Mandatory Information Security Compliance Programs
