ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the storage of information on print media and in particular discloses a Card Information System.
CROSS REFERENCES TO RELATED APPLICATIONS
The following Australian provisional patent applications are hereby incorporated by cross-reference. For the purposes of location and identification, U.S. patent applications, identified by their U.S. patent application serial numbers (USSN) are listed alongside the Australian applications from which the U.S. patent applications claim the right of priority.
BACKGROUND OF THE INVENTION
Many forms of condensed information storage are well known. 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. In respect of portable discs, “Floppy Discs”, “Zip Discs”, and other forms of portable magnetic storage media have to achieve to date a large degree of acceptance in the market place.
Another form of portable storage is the compact disc “CD” which utilizes a series of elongated pits along a spiral track which is read by a laser beam device. The utilization of CD's provides for an extremely low cost form of storage. However, the technologies involved are quite complex and the use of rewritable CD type devices is extremely limited.
Other forms of storage include magnetic cards, often utilized for credit cards or the like. These cards normally have a magnetic strip on the back for recording information which is of relevance to the card user. 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. Unfortunately, the cost of such devices is often high and the complexity of the technology utilized can also be significant.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an alternative form of information storage which includes a high level of versatility with a low cost of distribution and production.
In accordance with a first aspect of the present invention, there is provided a method of information distribution on printed cards, the method comprising the steps of dividing the surface of the card into a number of predetermined areas; printing a first collection of data to be stored in a first one of the predetermined areas; utilising the printed first predetermined area when reading information stored on the card; and, when the information stored on the card is to be updated, determining a second one of the predetermined areas to print further information stored on the card, the second area not having being previously utilized to print data.
Preferably, the areas are selected in a predetermined order and the printing utilizes a high resolution ink dot printer for printing data having a degree of fault tolerance with the fault tolerance, for example, coming from Reed-Solomon encoding of the data. Printed border regions delineating the border of the area can be provided, in addition to a number of border target markers to assist in indicating the location of the regions. The border targets can comprise a large area of a first colour with a small region of a second colour located centrally in the first area.
Preferably, the data is printed utilising a high frequency modulating signal such as a checkerboard pattern. The printing can be an array of dots having a resolution of greater then substantially 1200 dots per inch and preferably at least 1600 dots per inch. The predetermined areas can be arranged in a regular array on the surface of the card and the card can be of a generally rectangular credit card sized shape.
