1. A card generator system for generating an ID (identity) card of a user, the card generator system comprising a processor and a memory storing a computer program code executable to cause the processor to:
capture biographic information from the user;
capture biometric information from the user;
compile a data string formed from data from at least one of the biographic and information or the biometric information;
hash the compiled data string into a hashed value, including sending only the hashed value to a hashed data string database, sending no other identifying data about the user to the hashed data string database, and filtering data to prevent transmission of any information to the hashed data string database other than a hashed data string; and
store the data string on the ID card.
