Abstract
Abstract A transducer apparatus for use with cards bearing a magnetic recording stripe and having an optically sensible anticounterfeit uniqueness characteristic, the apparatus including a sensor for the anticounterfeit characteristic which scans the card by a small discrete window of perception, pixel. The apparatus isolates predetermined areas of perception for the card, so as to verify on the basis of signals from a prior observation recorded by the magnetic stripe. Areas of perception, pixel size, are less than one sixty-fourth of a square inch. The magnetic sensing head of the apparatus is mounted with the anticounterfeit sensor to accommodate common resilient displacement with movement relative to a card.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
A transducer apparatus for use with cards or the like to concurrently sense magnetic data and displaced yet space-related anticounterfeit characteristic data from a card, said anticounterfeit characteristic data being sensed by radiant energy from said card, said transducer apparatus comprising: a frame member defining a slot passage for receiving a moving card; a magnetic head assembly for sensing said magnetic data; an anticounterfeit characteristic radiant energy sensor for sensing said anticounterfeit characteristic data which is displaced from said magnetic data on said card; and a flexible support for said magnetic head assembly and said anticounterfeit characteristic radiant energy sensor for supporting said magnetic head assembly and said anticounterfeit radiant energy sensor in spaced-apart relationship with respect to said card whereby said magnetic head assembly senses said magnetic data and said radiant energy sensor senses said displaced anticounterfeit characteristic data, said support being affixed to said frame member whereby said magnetic head and said characteristic radiant energy sensor are rigidly joined for limited common displacement in contiguous relationship to said passage whereby to sense co-related radiant energy and magnetic signals from said card while moving to accommodate the displacement of said card through said slot passage.
Claim 2
Dependent Claim
196 words
A transducer apparatus for use with cards or the like to concurrently sense magnetic data and displaced yet space-related anticounterfeit characteristic data from a card, said anticounterfeit characteristic data being sensed by radiant energy from said card, said transducer apparatus comprising: a frame member defining a slot passage for receiving a moving card; a magnetic head assembly for sensing said magnetic data; an anticounterfeit characteristic radiant energy sensor for sensing said anticounterfeit characteristic data which is displaced from said magnetic data on said card; and a flexible support for said magnetic head assembly and said anticounterfeit characteristic radiant energy sensor for supporting said magnetic head assembly and said anticounterfeit radiant energy sensor in spaced-apart relationship with respect to said card whereby said magnetic head assembly senses said magnetic data and said radiant energy sensor senses said displaced anticounterfeit characteristic data, said support being affixed to said frame member whereby said magnetic head and said characteristic radiant energy sensor are rigidly joined for limited common displacement in contiguous relationship to said passage whereby to sense co-related radiant energy and magnetic signals from said card while moving to accommodate the displacement of said card through said slot passage.
Claim 3
Dependent Claim
14 words
An apparatus according to claim 1 wherein said flexible support comprises a leaf-spring means.
Claim 4
Dependent Claim
41 words
An apparatus according to claim 1 wherein said flexible support comprises a rigid mount for said head assembly and said sensor, and a pair of leafspring means affixed to said mount and a pair of tapered pins anchoring said spring means.
Claim 5
Dependent Claim
30 words
An apparatus according to claim 1 wherein said flexible support comprises means accommodating common displacement of said head assembly and said sensor substantially perpendicular to the plane of said slot.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 1 wherein said flexible support comprises means accommodating common displacement of said head assembly and said sensor in the directions of card movement through said slot.
Claim 7
Dependent Claim
26 words
An apparatus according to claim 1 further including means for processing signals sensed by said magnetic head assembly to sample signals sensed by said characteristic sensor.
Claim 8
Dependent Claim
19 words
An apparatus according to claim 6 further including means for testing said sample signals for comparison with reference values.
Claim 9
Dependent Claim
23 words
An apparatus according to claim 1 wherein said anticounterfeit characteristic sensor senses a pixel of less than one sixty-fourth of one square inch.
