- Alrighty... finaly a remake of the text I wrote on how to generate Credit
- Card #'s....
-
-
-
- ok first a quick bit of info on cc#'s:
- the first digit on a CC#, indicates what type of card it is (a 5 means
- master card, 4 Visa, 3 American Expres...) the first 3-6 digits are the
- bank ID code... and then for Master Card's you can have either 13-16
- digits... a CC# (16 digit) would appear like this 548559XXXXXXXXXC ok the
- 548559 is the Bank ID code for CitiBank, the X's are just random digits, (0
- - 9) and the C is the check digit.
-
- To generate a CC#, take your bank ID code (for our case [I like to use
- CitiBank] it will be 548559) and then for 16 digit CC#'s, generate 9 random
- digits... see below

- ------------------------------------ Even digits (2d 4th etc.)
-
- ok, first you take all the odd digits (the digits in odd places [look
- above]) and you multiply each one by 2, now if the result is higher than
- nine, you subtract nine... (i.e. 5 * 2 = 10; 10 - 9 = 1) now you do this
- for all of the odd placed digits... you add up the results, then you add up
- the even digits (don't multiply them by 2 or any of that crap) now take the
- next highest multiple of 10, and subtract the highest from the lowest and
- VOILA! your checkdigit... now you have a valid CC# below I will go through
- the steps for getting the checksum digit of the CC# above (in the example)
-
- 5*2=10;9-10=1
- 8*2=16;16-9=7
- 5*2=10;10-9=1
- 2*2=4
- 3*3=6
- 5*2=10;10-9=1
- 6*2=12;9-12=3
- 9*2=18;18-9=9
- 1+7+1+4+6+1+3+9=32
- 4+5+9+4+2+7+8=39
- 39+32=71
- Next highest multiple of 10 is 80
- 80-71=9
- check digit is 9
- CC# is 5485592432576899
- you can check the above # with Cmaster or Credit Wizard..
