The present invention provides an additional tier of authorization, which can be combined with any authorization procedures already in place for particular type of transactions. This new security schema uses variable identification number assigned to account owner as authorization signature for any transaction applied to his or her account. This additional feature allows transaction authorization process to be executed the same way regardless of whether or not particular account is participating in new authorization schema. That makes both types of accounts indistinguishable for the third party, which requested transaction.
