R, F, I, and D are the 18th, 6th, 9th, and 4th letters of the alphabet.
18 + 6 + 9 + 4 = 39. However, if you take the digits seperately and multiply them (3 x 9), you get 27. Since there are four letters in RFID, multiply 27 by 4. You have 108.
Now, since these four letters stand only for three words, we multiply it by 3. You get 324.
RFID is used at EZ Pass, which has two letters in it's title (EZ), so multiply it by 2. 648.
If you add the number of the age of a person using it who just became an adult (18), then you get....
...666.
IT'S TRUE O_O
