Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
97 words
A payment card for enabling the operation of vending machines by a user, comprising: a substantially rectangular flat card including first magnetic data storage means for storing information including value data including a first value, and means for displaying said first value; said first value representing an operating limit for said vending machines, said means for displaying said first value including a magnetically controllable non-volatile display storage means having a transparent front window and an opaque background, said display storage means being controllable by externally applied magnetic fields for replacing said first value with a second value.
Claim 2
Dependent Claim
97 words
A payment card for enabling the operation of vending machines by a user, comprising: a substantially rectangular flat card including first magnetic data storage means for storing information including value data including a first value, and means for displaying said first value; said first value representing an operating limit for said vending machines, said means for displaying said first value including a magnetically controllable non-volatile display storage means having a transparent front window and an opaque background, said display storage means being controllable by externally applied magnetic fields for replacing said first value with a second value.
Claim 3
Dependent Claim
31 words
A payment card as claimed in claim 1, said display means includes suspended magnetic particles of a first color and a background of a second color contrasting with said first color.
Claim 4
Dependent Claim
63 words
A payment card as claimed in claim 2, wherein said particles when subjected to a magnetic field will assume one of two preferred states, wherein said particles in a first of said two states provide an image in said first color, and in a second state provide an image in said second color; the combination of said images representing said readable value data.
Claim 5
Dependent Claim
24 words
A payment card as claimed in claim 3, wherein said magnetic particles are magnetized in patterns in said first color representing said data value.
Claim 6
Dependent Claim
31 words
A payment card as claimed in claim 3, wherein said magnetic particles are magnetized in elongated patterns in said first color, said elongated pattern having a length representing said data value.
Claim 7
Dependent Claim
26 words
A payment card as claimed in claim 5, wherein said card includes a scale located along said transparent front window for scaling said displayed elongated pattern.
Claim 8
Independent Claim
75 words
An apparatus for handling flat payment cards with visual value display means, said flat payment cards having first and second extensions and including first storage means for storing information, said apparatus comprising payment card handling means magnetic read/write means for reading information from said storage means and recording information in said storage means; magnetic erase/write means for erasing value data stored and displayed in said display means and recording value data in said display means.
Claim 9
Independent Claim
75 words
An apparatus for handling flat payment cards with visual value display means, said flat payment cards having first and second extensions and including first storage means for storing information, said apparatus comprising payment card handling means magnetic read/write means for reading information from said storage means and recording information in said storage means; magnetic erase/write means for erasing value data stored and displayed in said display means and recording value data in said display means.
Claim 10
Dependent Claim
30 words
An apparatus as claimed in claim 7 wherein said erase/write means include means for simultaneously storing pattern segments in said display means and said information in said first storage means.
Claim 11
Dependent Claim
27 words
An apparatus as claimed in claim 7 including control means for coordinating movement of said payment card with sequentially recording said data value in said display means.
Claim 12
Dependent Claim
55 words
An apparatus as claimed in claim 7 wherein said erase/write means include a plurality of first magnetic means arranged in a predetermined arrangement; said apparatus further including first control means for activating selected ones of said first magnetic means; said activated first magnetic means causing said display means to store and display said data value.
Claim 13
Independent Claim
135 words
An apparatus for handling flat payment cards with visual value display means, said flat payment cards having first and second extensions and including storage means for storing information, said apparatus comprising payment card handling means magnetic read/write means for reading information from said storage means and recording information in said storage means; magnetic erase/write means for successively erasing value data stored and displayed in said display means, and recording value data in said display means; wherein said erase/write means include a plurality of first magnetic means arranged in a predetermined arrangement; said apparatus further including control means for advancing said payment card in a direction of said first or second extension for successively writing adjacent pattern segments to said display means; the combination of said pattern segments constituting a display pattern representing said data value.
Claim 14
Independent Claim
135 words
An apparatus for handling flat payment cards with visual value display means, said flat payment cards having first and second extensions and including storage means for storing information, said apparatus comprising payment card handling means magnetic read/write means for reading information from said storage means and recording information in said storage means; magnetic erase/write means for successively erasing value data stored and displayed in said display means, and recording value data in said display means; wherein said erase/write means include a plurality of first magnetic means arranged in a predetermined arrangement; said apparatus further including control means for advancing said payment card in a direction of said first or second extension for successively writing adjacent pattern segments to said display means; the combination of said pattern segments constituting a display pattern representing said data value.
