Tokenization is a method for protecting card data by substituting a card's Primary Account Number (PAN) with a unique, randomly generated sequence of numbers, alphanumeric characters, or a combination of a truncated PAN and a random alphanumeric sequence.
Tokenization was applied to payment card data by Shift4 Corporation and released to the public during an industry Security Summit in Las Vegas, Nevada in 2005. The technology is meant to prevent the theft of the credit card information in storage.
