The fucking article. Often used in the construct RTFA (read the fucking article), itself derived from RTFM, it is often used on the slashdot news site, where it is common knowledge that most of the posters will comment on stories without reading the articles linked to in the main story.
TFA clearly states that your point is utter BS. So, next time, please RTFA before making a fool out of yourself on /.

Two Factor Authentication. Or Three Factor Authentication. (You see, there's ambiguity in the definition of this TLA)

In most situation, you only need a single factor to authenticate, to prove who you are: "Something you know" - typically a password. But that's not very secure. Therefore, some systems make authentication stronger by requiring more than just one factor. Other factors are "something you are" (such as your fingerprint, or other biometric aspects such as your signature) and "something you have" (such as a key, or a chipcard).
Every ATM I have seen so far employs TFA: In order to get money out of it, you have to prove that you're the legitimate account holder by providing two things: Something you have (your ATM card) and something you know (your PIN).
