Appendix A of this document contains the worksheet to
determine eligibility to reduce your PCI scope.
What had not been clearly
defined before has now been defined for manufactures to comply with PCI
requirements for devices and encryption beyond the normal pin pads and pin
numbers. This new information will apply
to mobile devices as well.
Please note there is language that specifically states that the end to end encryption does not take the merchant totally out of scope for PCI compliance, however this is a very big step forward.
