Abstract: A conventional Touch-Tone telephone instrument is rendered functional in the same manner and to the same extent as a computer terminal having alpha-numeric capability, as regards transmission of queries directed to computerized data bases. It is also rendered functional as a recipient of information transmitted from the data base through a telephone network to provide intelligence heretofore made available only on the video screen of the computer terminal, or through automatic printers. Disclosed is the substitution of the instrument for a computer terminal and its associated video screen or teleprinter, without requirement of modification of the instrument, so that a subscriber gains from the use of the telephone functions heretofore obtainable only by providing oneself with a computer terminal and its associated screen and/or automatic printer. The user spells out one or more words by depressing the conventional, alpha-numerically marked keys of a Touch-Tone telephone instrument.

Abstract: A system especially adapted for facilitating the collection of tolls on highways, includes the provision of exteriorly visible bar codes or other machine-readable customer account identifications, on vehicles using toll roads. Issuance of the account identification elements enables the customer to pass assigned scanning locations where the elements are machine-read, and verified at a computerized station serving a selected number of scanning locations. Through a computerized network, the scanned data is ultimately transmitted to credit-issuing companies, for billing to the customers who have used the machine-readable elements. The system permits a vehicle to continue past the scan point without stopping, thus offering maximum convenience to motorists, speeding up the flow of traffic, and reducing the number of personnel required at highway toll plazas.
