(c) with each value in the upper region, designating the corresponding bit value to be a second value and (b) with each value in the lower region, designating the corresponding bit value to be a first value (a) dividing a sensed data value into three contiguous regions comprising a middle region, a lower region, and an upper region, and: In accordance with a first aspect of the invention, there is provided a method of determining an output data value of sensed data, the method comprising the steps of: Unfortunately, the cost of such devices is often high and the complexity of the technology utilized can also be significant. Recently, the convenience of magnetic cards has been extended in the form of SmartCard technology which includes incorporation of integrated circuit type devices on to the card. These cards normally have a magnetic strip on the back for recording information which is of relevance to the card user. Other forms of storage include magnetic cards, often utilized for credit cards or the like. However, the technologies involved are quite complex and the use of rewritable CD type devices is extremely limited.

The utilization of Compact Disks provides for an extremely low cost form of storage.

Another form of portable storage is the compact disc вЂњCDвЂќ which utilizes a series of elongated pits along a spiral track which is read by a laser beam device. In respect of portable discs, вЂњFloppy DiscsвЂќ, вЂњZip DiscsвЂќ, and other forms of portable magnetic storage media have achieved a large degree of acceptance on the market place. For example, in the field of computer devices, it is common to utilize magnetic disc drives which can be of a fixed or portable nature. Many forms of condensed information storage are well known. Reader intensity variations should also be accounted for in any system or method implemented in the data contained on the surface of the card.

The scanner of the surface of the card may experience various device fluctuations such that the intensity of individual pixels may vary. These motor fluctuation errors should also be tolerated by the data encoding method on the surface of the card. The electric motor may experience a degree of fluctuation which will result in fluctuations in the rate of transmission of the data across the surface of the CCD. Further, the card reader is assumed to be driven past a CCD type scanner device by means of an electric motor. This play can comprise a degree of rotation of the card when read by a card reader. A certain degree of вЂњplayвЂќ exists in the insertion of the card into a card reader. Various data errors on the surface of the card may rise and any scuffs or blotches should be tolerated by any system determining the information stored on the surface of the card. Such text writing errors are ideally tolerated by any scanning system scanning the card. The system adopted should tolerate writing errors wherein text is written by the owner of the card on the surface. Dead pixel errors which are a result of reading the surface of the card with a linear CCD having a faulty pixel reader for a line thereby producing the same value for all points on the line. For example, the form of distribution can suffer a number of data corruption errors when the surface is scanned by a scanning device. There is a general need for a print media scanning system that allows for high volumes of computer data to be stored on simple print media, such as a card, and to simultaneously be able to tolerate a high degree of corruption of the data. Further, magnetic ink scanning systems have particular application on bank cheques which are automatically scanned and the original data determined from the cheque. For example, barcodes are often utilised in conjunction with an optical scanner for the distribution of corresponding barcode data. Methods for distribution of data for automatic reading by computer systems are well known. The present invention relates to a data distribution system and in particular discloses a data distribution mechanism in the form of Dotcards.
