The PCI Security Standards Council (PCI SSC) and financial services standards outfit the Accredited Standards Committee X9 have decided to combine forces on personal-identification-number-handling-rules.
Today, both have their own standards, which is a pain for organisations like banks that follow rules set by both organisations. The overlapping standards also make life hard for assessors who may consider an organisation's PCI compliance is not in order if they adhere to the X9 rules.
The Register imagines a few readers don't enjoy having to figure out how to get the two standards running alongside each other.
Hence the decision to consolidate the PCI PIN Security Standard and the X9 TR39 PIN Standard.
