Difference between credit card tokenization vs encryption
In: Other
Encryption is using mathematical properties of numbers to convert your credit card information to an encrypted number that cannot be deciphered unless you have the encryption key. If a hacker manages to get the encrypted number and the key, he will get your exact credit card number.
Tokenization is using a temporary substitute credit card number for a specific service or transaction. Your credit card provider issues this number and it can be used later on, removing the need for storing your real credit card number. In this case, if the hacker can get the token, he will not have access to your credit card number. The token can be invalidated, effectively neutralizing any uses of it.
