Abstract
An improved system for transmission financial data includes, in preferred embodiments, an encryption key stored on a bank card and used to encrypt preselected data prior to transmission. Encrypted data is then transmitted through all intermediate computers without decryption and reencryption. Decryption occurs only at the final destination, where the encryption key has been stored. In preferred embodiments, the encryption key is combined with a terminal identification valve to provide further security.
