Detect CREDIT_CARD

[JD84395]

A Credit Card is considered very valuable Personal Identifiable Information (PII) and should be a high priority for protection because it is many peoples primary method of paying for goods, services etc. The credit card was a massive innovation moving people away from using cash for every purchase to simply swiping a card for most purchases as it is much more convenient than carrying dollar bills around. However, with this convenience comes the risk of centralizing a portion of your purchasing power in one place and tying your identity to it. If credit card numbers are stolen by a bad actor, they can steal your money and make purchases under your name. For more information about credit cards, visit click here
