At the beginning of this year, the credit card organizations VISA and MasterCard have agreed on common standards in order to achieve a consistent course of action for the application of security requirements. These ‘Payment Card Industry (PCI) Data Security Standards’ are valid for the entire credit card payment industry.
The PCI regulations specify 12 requirements for compliance that have to be fulfilled by all merchants accepting VISA cards and by service providers:
Build and Maintain a Secure Network
1. Install and maintain a firewall configuration to protect cardholder data
2. Do not use vendor-supplied defaults for system passwords and other security parameters
Protect Cardholder Data
3. Protect stored cardholder data. Do not store unnecessary card or transaction data like full card number, magnetic stripe data, card verification code (CVV2) or PIN.
4. Encrypt transmission of cardholder data and sensitive information across open, public networks.
Maintain a Vulnerability Management Program
5. Use and regularly update anti-virus software
6. Develop and maintain secure systems and applications
Implement Strong Access Control Measures
7. Restrict access to cardholder data by business need-to-know
8. Assign a unique ID to each person with computer access
9. Restrict physical access to cardholder data
Regularly Monitor and Test Networks
10. Track and monitor all access to network resources and cardholder data
11. Regularly test security systems and processes
Maintain an Information Security Policy
12. Maintain a policy that addresses information security

One of the most important elements in the 12-point PCI data security program is the prohibition of storing full credit card and CVV data in any form after successful authorization. This is crucial because access to this highly sensitive data facilitates forging of credit cards.
If an audit discovers that you as a merchant are storing credit card data at the POS (cash register), in the PMS (Front Office System) or in your company office, there is an increased likelihood that VISA may fine your bank and your bank will pass the fine to you for non-compliance. VISA is well aware that certain POS and PMS products store credit card data.
As a matter of course all IT providers for the entire industry are affected, as well as your transaction service provider. Please also have your transaction service provider confirm PCI compliance.
