The Payment Card Industry Data Security Standard (PCI DSS) was created in 2004 by a joint initiative of Visa USA, MasterCard International, American Express and Discover.
The standard is a consolidation of the individual programs and security policies of the major credit card associations listed below:
Visa USA – The Cardholder Information Security Program (CISP)
MasterCard – The Site Data Protection Program (SDP)
American Express – The Data Security Operating Policy (DSOP)
Discover – Discover Information Security and Compliance (DISC)
More information on each of these programs can be obtained by clicking the links in the left pane.
The PCI DSS defines a consolidated list of requirements that all merchants are required to comply with.
The Payment Card Industry Data Security Standard is comprised of a set of 12 requirements each of which focuses on an aspect of the overall security in the payment card industry. These requirements include security of the network, security of stored data, encryption of transmissions, logging and audit trails, access controls and anti virus systems etc.
Compliance with the PCI DSS has become an increasingly significant concern for companies that process, store or transmit credit card data.
The PCI data security standard classifies merchants based on the annual number of transactions processed by that merchant. The following tables lists the 4 levels currently being used by Visa.
|
Merchant Level |
Description |
|
1 |
Any merchant, regardless of acceptance channel, processing over 6,000,000 Visa transactions per year.
Any merchant that has suffered a hack or an attack that resulted in an account data compromise.
Any merchant that Visa, at its sole discretion, determines should meet the Level 1 merchant requirements to minimize risk to the Visa system.
Any merchant identified by any other payment card brand as Level 1.
|
|
2 |
Any merchant processing 150,000 to 6,000,000 Visa e-commerce transactions per year. |
|
3 |
Any merchant processing 20,000 to 150,000 Visa e-commerce transactions per year. |
|
4 |
Any merchant processing fewer than 20,000 Visa e-commerce transactions per year, and all other merchants processing up to 6,000,000 Visa transactions per year. |
Based on the level of the merchant, there are specific requirements that the merchant must fulfill in order to be compliant with the PCI standard.
