The latest PCI-DSS compliance stats for the U.S. released by Visa on Monday (August 2) show a tiny increase in the compliance rate for Level 1 retailers since the last report, from 95 percent to 96 percent. The increase, though, may be a statistical anomaly: The number of merchants in that category dropped from 360--where it had been for the last two reports--down to 358. If one of those retailers was non-compliant, that might explain the difference right there.
Level 2 also saw a one-percent increase, from 94 percent--where that group had been for the last couple of reports--to 95 percent. The compliance stats for Levels 3 and 4 were again not reported, beyond the vague level of "moderate."
