Abstract
An authority verification system for verifying the authority of the user of a credit or other account by assigning a different code name to each account. When an account is used, the code name, in enciphered form is written on a certificate along with other information necessary to debit the credit account. Verification apparatus deciphers the code name and compares it with the code name assigned to the account being debited. In addition, when the credit or other account is either a checking account or charge account, other enciphered codes may be included on each check and credit card to protect against alteration of the check or credit card and thus assure check or credit card authenticity.
