Javascript credit card generator fix

Posted in Credit card at 21:40 by graham

There was a mistake in the Javascript credit card generator, meaning it would not work on MS Internet Explorer or Opera. This has now been fixed, and I have tested it successfully on:

  • Firefox 1.0.6
  • Konqueror 3.4.1
  • Internet Explorer 6.0
  • Opera 8.5.2

The archive now also includes an example on how to use the Javascript version (which seems the most popular).

Free credit cards

Posted in Credit card at 20:09 by graham

As you can probably tell from some of the comments in the credit card section, some people don’t seem to understand that the generator just makes numbers that look like credit cards, but are IN NO WAY actual credit card numbers.

So, in the hope of preventing any further requests for a card (I delete about 10 a day), here is the ultimate guide to getting your own free credit card

Many thanks to R from Aus for posting this on the previous incarnation of this site

CVV numbers

Posted in Credit card at 17:46 by graham

CVVs, CVV2s, CVCs, and Indent CVCs are 3-digit Card Verification Values or Card Verification Codes that are all calculated using the same CVV algorithm. These values are required by payment systems such as Visa and MasterCard to authenticate their credit or debit cards. Different names are used to refer to the values depending on the particular payment system, the location of the value on the card, and the parameters passed to the CVV algorithm.

To calculate a 3-digit CVV, the CVV algorithm requires a Primary Account Number (PAN), a 4-digit Expiration Date, a 3-digit Service Code, and a pair of DES keys (CVKs).

Besides the obvious CVV variations provided by different PANs and expiration dates, most card issuers will use different CVKs for different batches of cards. Cards can be grouped by bank, by ATM network, or by other means of identifying a certain group of cards. Cards in the same batch will often use the same service code. This service code to the CVV algorithmis usually non-zero. One CVV variant, now commonly called CVV2 (Visa), or Indent CVC (MasterCard), uses ‘000’ as the service code parameter to the CVV algorithm. Sometimes a card will have both a traditional CVV and a CVV2.

Another variation to the CVV algorithm can be introduced by changing the format of the expiration date. While the date is always the concatenation of the 2-digit month (MM) andlast 2 digits of the year (YY), it can be in either YYMM or MMYY formats. For instance, Visa CVV2s are usually calculated using the YYMM format.

Luhn formula

Posted in Credit card at 17:44 by graham

A credit card number must be from 13 to 16 digits long. The last digit of the number is the check digit. That number is calculated from an algorithm (called the Luhn formula or MOD 10) on the other numbers. This is to spot typos when a user enters a number, and I assume was to allow detecting an error reading the magnetic stripe when a card is swiped.

The MOD 10 check does not offer security, it offers error detection. Think of it as fullfilling the same role as a CRC in software.

To calculate the check digit:

First drop the last digit from the card number (because that’s what we are trying to calculate)

Reverse the number

Multiply all the digits in odd positions (The first digit, the third digit, etc) by 2.

If any one is greater than 9 subtract 9 from it.

Sum those numbers up

Add the even numbered digits (the second, fourth, etc) to the number you got in the previous step

The check digit is the amount you need to add to that number to make a multiple of 10. So if you got 68 in the previous step the check digit would be 2. You can calculate the digit in code using checkdigit = ((sum / 10 + 1) * 10 – sum) % 10

For an example of this in practice download the code to the credit card number generator.

Credit card numbers are a special type of ISO 7812 numbers.
