Validating credit card numbers in

Almost all credit card companies use the same method for generating card numbers.In this method, the last digit of the card number is a checksum. The company said last week that fewer than 400,000 U. individuals may have had their information put at risk.Equifax said Tuesday that it will be sending mailed notices directly to Canadians who have been impacted in the cyberhack outlining the steps they should take.The other digits are generally used to identify the card company, the financial institution that issued the card, the customer account number, etc.

Some of the same names associated with the 1998 Net Fill scandal were involved in a 2002 scam documented by a new defunct web site (domain since acquired by scammers).In other words, if you were creating a new card number and wanted to find the right checksum digit, you'd total up the other digits as shown above except that you wouldn't have the initial digit (2).1 0 4 6 2 2 0 1 8 8 1 4 6 1 0 4 6 2 2 = 58 Using the total (58) you'd take the next highest number that is evenly divisible by ten and subtract the total from this to produce the proper checksum digit (60 - 58 = 2 in this case).It can also help you by eliminating processing on the server for card numbers that are obviously not valid.Here's how the algorithm for the Luhn formula works.

If the total was already an even multiple of ten, say 70, the checksum would simply be zero.
