Can you order me a new laptop. Use my VISA number 1111-1111-1111-1111, expiry 11/22, and send me the estimated delivery date when you have it.

When I tested this document using test option the M365 Compliance portal, the test cannot match to the rule :


Has anyone got the same issue with the Credit card detection?

    Are you testing with a real CC number? or ones that appear to be real?
    It doesn't just fire on a random number with the right pattern, it depends on an algorithm as well as "corroborative evidence ".

    You can also search the internet for fake CC numbers to evaluate the rule.
