Abstract: An optical information-bearing debit card having servo tracks and calibration works on a recording medium for aligning a reading or writing light beam with a nearby value site area. The medium is an elongated strip of reflective information storage material adhered to a self-supporting card, like a credit card. The value site area may be decremented by the light beam changing the optical characteristics of the recording medium. The servo tracks are lengthwise, parallel to the long dimension of the strip of recording material while the calibration marks are non-continuous marks, aligned in a track parallel to the servo tracks. Tracks and calibration marks are disposed on the card so that the value area can be read bidirectionally starting from either end of the card.

Abstract: A ticket handling system for use in a ticket preparation system that includes a signal processor for providing print signals to indicate information to be printed on the tickets and write signals to indicate information to be encoded on the tickets; a printer for printing information on ticket stock in response to the print signals; and a transducer for encoding information on the ticket stock in response to the write signals. The ticket handling system includes a feeder module including a feed system for feeding a strip of ticket stock; a cutter module; a cutting device for cutting ticket blanks of a given length from the fed end of the strip; a printer module including the printer for printing ticket information on the ticket blanks in response to the print signals; and a transport module including the transducer for encoding ticket information on the ticket blanks in response to the write signals.

Abstract: A method for inhibiting tampering with data on a magnetic stripe card is disclosed. The data are erased if the card is prematurely withdrawn from the reader/writer. A write protect bit is set and recorded on the card if the power source is interrupted. Apparatus for activating the tamper-proofing techniques are disclosed.

Abstract: This invention relates to a mechanison to read and process a prepaid, flexible, magnetically coded card bearing marked sections adapted be cut off representing value used. Upon insertion into the mechanison a forward/reverse drive means takes control of the card. The card is read and a decoder processes the code signals and signals a "good code" or "bad code" output which activates the forward or reverse drive of the card and associated means, including a card shear which acts upon the card at the decoder relected position, and to return the card.

Abstract: The invention relates to a combination of an apparatus for the transfer of fungible goods or services, for example, cashless payment for merchandise or services, with a transfer device having marked thereon a plurality of cancellable value units in the form of at least first and second types of optical markings different from one another, and arranged in a predetermined cyclical sequence on at least one track of the transfer device, without the occurrence of any gaps, but with a transition region formed between adjacent markings. The apparatus includes a reading device, inclusive of a light source, and at least first and second light sensors associated with the first and second types of optical markings, respectively. The reading device is arranged for reading and generating signals from the markings, and from the transition regions, and an activatable erasing device erases the markings in dependence of the number of value units to be cancelled.

Abstract: A switching arrangement for the recording of value balance information on a magnetic track disposed on a charge card. The arrangement is characterized in that a balancing circuit is connected to a reading-writing device with reading and writing heads and to a debiting circuit as well as to a balance recording device.

Abstract: A document transport for data entry and document processing for such documents as checks or credit card slips with transport means for entering the documents into a feed station, moving the documents past two read stations, wait in a hold station then return through a print station and a validator station with provision for entering data into the system and printing upon the document. The transport moves document in one direction and is reversed and moves documents in a second direction in the processing steps prior to depositing the document into a stack station.

Abstract: A card reader is disclosed for reading cards and like materials one at a time, the card reader having a transport mechanism and special control circuitry for control of same so as to provide single feed card transport over a predetermined transport cycle. The reader controls provide means for selecting the amount of data to be read from the transported card and for controlling the transport cycle in accordance with the selected portion of the card which is to be read. The reader of this invention is suitably a subcombination of an addressable system comprising a plurality of like devices which are addressably controlled by a central processing unit.

Abstract: The disclosure relates to a control system for use in an information retrieval system. The control system adapts the retrieval system for locating a preselected information bearing element wherein the information bearing elements comprise a first set of elements numbered consecutively in a first direction for identification and a second set of elements numbered consecutively in a second direction for identification and wherein each element of the first set is associated with an identifiable marker comprising a first set of markers and each element of the second set is associated with an identifiable marker comprising a second set of markers.

Abstract: A high speed tape reader has a buffer positioned between the read head output and the reader output which may be connected to the input of a data receiving station. When the data receiving station sends a signal to the tape reader that it has stopped accepting data, the tape reader slows gradually to a stop. While the tape is slowing, the characters on the tape move by the read head on the tape reader and these characters are read by the tape reader but instead of being transmitted to the data receiving stations, they are stored and accumulated in the buffer in the same sequence that the characters appear on the tape. Thereafter, when the data receiving station requests more data, the data is first taken off the buffer output in the same order it entered into the buffer to prevent the tape reader from skipping characters when it received the signal that the data receiving stations are no longer accepting data.
