A system for reading data words contained in portable data storage means, said data words representative of data signals from a data source, and for treating said data signals comprising:

• reader means including:
• a receptable for receiving said portable data storage means in signal communicating relationship, first and second signal storage means, and first signal processing means responsive to an activation command signal for transferring a first group of said data words from a predetermined location within said portable data storage means to said first signal storage means, said signal processing means being further responsive to a transmit command signal for transmitting said first group of data words stored within said first signal storage means to said second signal storage means and then to an output of said reader means and for transferring a second group of data words from said portable data storage means to said first signal storage means while said first group of data words are being transmitted from said second signal storage means;
• and
• translator means having an input for receiving, when activated, signals representing said transmitted data words from said output of said reader means and including second signal processor means for generating said activation command signal and said transmit command signal and for analyzing the validity of said transmitted data words and effecting the select recordation thereof upon a storage medium.
