3.4 — PAN is masked when displayed and protected from copying
Requirement
PAN is masked when displayed so that only personnel with a legitimate business need can see more than the BIN and last four digits, and technical controls prevent copying or relocating PAN via remote-access technologies except with explicit authorisation.
What the engine looks for
Every group below must be satisfied — by an affirmative statement, not a plan, a hedge or a denial — for the control to count as covered. A term ending in … matches any word it begins. Supporting terms do not change the verdict — they raise confidence and distinguish a policy that names a mechanism from one that gestures at a category.
Finding any of these outranks coverage — a policy that admits the gap is worse than silence.
