Abstract

An optically readable digital bar code comprising two rows of printed spaces and non-printed spaces, one row being a calibration row for reading the data row; and a scanner having two optical reading heads controllably joined together and disposed side by side for reading the code and for converting it to data and outputting the data. Also shown is method of storing data as a bar code and a communication system including the bar code and the scanner. The bar code and scanner are useful within a method and system for authorizing and carrying out a financial transaction comprising providing an authorized user password and a single-use code carrier, both associated with a single-use transaction code which is associated with a transaction account; receiving the transaction code and the password for requesting authorization of a financial transaction; verifying the transaction code and the password; nullifying the transaction code for further use; and authorizing the financial transaction; the above steps being carried out via a communications network.
