 Tokenization as a security strategy lies in the ability to replace a real card number with a surrogate (target removal) and the subsequent limitations placed on the surrogate card number (risk reduction).If the surrogate value can be used in an unlimited fashion or even in a broadly applicable manner as with Apple Pay, the token value gains as much value as the real credit card number.In these cases, the token may be secured by a second dynamic token that is unique for each transaction and also associated to a specific payment card.
