X-Cart:PCI-DSS
Contents
PCI Compliance is increasingly important to all online store owners, and X-Cart can be implemented to meet this standard. Follow the steps when implementing X-Cart in a PCI compliant manner.
About PCI DSS
PCI DSS stands for Payment Card Industry Data Security Standard, which is a worldwide information security standard assembled by the major credit card vendors, including American Express, Discover Financial Services, JCB International, MasterCard Worldwide, and Visa, Inc. The standard was designed to help organizations involved in processing credit card payments online make their payment systems secure from cardholder data fraud.
PCI DSS specifies 12 requirements broken into 6 groups for compliance that apply both to hardware and software parts of the system that is used to collect, store, transmit and process valuable credit card data as well as the human factor.

Configuring X-Cart to meet PCI DSS (cardholder data is not stored)
Disable collecting of credit card data at user registration
If forced, X-Cart can collect customers' credit card details during registration. This is controlled via two check boxes in the section General Settings / General Options of the Admin area:
- Do not ask customers to enter CC information while getting registered: Defines if a customer will be asked to provide credit card details during registration;
- Display CVV2 input box on the registration form and at the last stage of checkout if Manual CC processing is used...: Defines if a customer will be asked to provide CVV2 during registration.
Asking for credit card data during registration must be disabled as shown in the picture below.
Disable storing credit card data in X-Cart database
If forced, X-Cart can store valuable credit card data in an encrypted database. This is controlled via three variables in the main configuration file <xcart_dir>/config.php. You must set the value of all the three variables to false (which is the default setting), and no credit card will be stored in the X-Cart database then.
# file <xcart_dir>/config.php
$store_cc = false
$store_ch = false
$store_cvv2 = false
Remove historical data
Removing historical data, such as card validation codes and other credit card information after the orders using it have been processed and completed, is absolutely necessary for PCI DSS compliance. To remove this data use the Summary > Tools section of X-Cart admin back-end.
Disable Subscriptions module
When the built-in X-Cart module Subscriptions is enabled, X-Cart keeps credit card data stored in its database. Follow these steps to disable the module:
- Log in to the X-Cart Admin area.
- Go to the section Modules (Administration module -> Modules)
- Deselect the check box for the entry Subscriptions.
- Click the Update button at the bottom of the page to save the changes.
Secure processing and transmission of cardholder data
The easiest way to deal with PCI-DSS compliance is to use web-based payment gateways to eliminate the need for customers to enter credit card details on your web-site and thus reduce efforts on meeting PCI-DSS compliance requirements. X-Cart is secure and supports quite a number of such “offsite” payment gateways like Paypal Express Checkout, Google Checkout, WorldPay, 2Checkout, Authorize.net SIM and many more.
If your store has a background payment method enabled, customers input their credit card data on the X-Cart side at the final step of checkout. It is highly recommended to disable background payment methods using the Settings menu -> Payment methods section of the X-Cart admin back-end. In this case you'll have to fill out the simplest of PCI Self-Assessment Questionnaires (SAQ A).
If you want credit card data to be entered on X-Cart side, it's necessary to make sure that your store is implemented in a PCI-compliant hosting environment and your X-Cart is set up in a PCI-compliant manner, i.e. you use a PA-DSS certified software to process credit card payments. You'll have to fill out PCI SAQ C in this case.
Configuring X-Cart to meet PCI-DSS with X-Payments application
Why use X-Payments
Being PA-DSS certified X-Payments helps merchants to meet PCI standards. Implementing X-Payments with X-Cart saves merchants time and money when it comes to complying with PCI DSS.
Understanding PA-DSS
If a software application stores, transmits or processes sensitive cardholder data the application must be PA-DSS compliant.
- Requires all payment applications be certified by an approved Payment Application-Qualified Security Assessor (PA-QSA). PA-QSAs are third-party security auditors, certified by the PCI-Security Standards Council (PCI-SCC) to verify that payment applications meet specified security standards
- PA-DSS payment applications must be implemented in a PCI DSS compliant environment
Becoming compliant easy
Qualiteam has helped to make PCI compliance easier for merchants by separating the X-Payments application from the X-Cart platform. There are two important benefits of this design:
- Only the actual payment application has to be certified and compliant - rather than the entire platform
- X-Cart can be upgraded and customized without affecting the overall PCI compliance provided by X-Payments

To become compliant SAQ C must be completed.
