Earlier this month Visa USA warned banks that process card transactions for non-PCI compliant Level 1 and 2 merchants that they will face higher commission fees and monthly fines of at least $25,000 starting October 1st. These banks then passed the news on to their merchants. Non-compliant Level 1 merchants will be fined starting in October and Level 2 merchants in January 2008.

[Editor's note (Valle): Many large companies that transact over 6 million credit card transaction a year (Level 1) or 1-6 million transaction (Level 2) are still not PCI compliant. In our experience many companies ultimately decide to purchase internal firewalls and IDS products for their PCI project.]
