Abstract
Abstract A magnetic card comprising a plasticized rectangular support equipped on or under one of the surfaces thereof with at least one magnetic track, the two edges of which are essentially parallel with respect to each other and to the longitudinal edges of the card characterized in that the contour thereof includes at least one longitudinal notch in one of the longitudinal edges whose depth is in the order of several tenths of millimeters.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
A magnetic card adaptable to be inserted into a slot of a magnetic reader, comprising: a plasticized generally rectangular support means provided with a pair of longitudinally extending edge portions and a first pair of transversely extending edge portions, said edge portions defining therebetween an indicia receiving surface; at least one magnetic track provided on a portion of said indicia receiving surface of said support means; at least one line of non-coded indicia in the form of raised characters provided on a portion of said indicia receiving surface; and means provided in one of said pair of longitudinally extending edge portions for preventing the wedging of the card in the slot of the magnetic reader including: a second pair of transversely extending edge portions provided in said at least one of said pair of longitudinally extending edge portions between said first pair of transversely extending edge portions, and an additional longitudinally extending edge portion disposed between said second pair of transversely extending edge portions, said second pair of transversely extending edge portions and said additional longitudinally extending edge portion defining therebetween a recess for compensating for deformation of the card resulting from providing the card with raised characters, said recess extending substantially over the entire length of the longest line of non-coded indicia.
Claim 2
Dependent Claim
213 words
A magnetic card adaptable to be inserted into a slot of a magnetic reader, comprising: a plasticized generally rectangular support means provided with a pair of longitudinally extending edge portions and a first pair of transversely extending edge portions, said edge portions defining therebetween an indicia receiving surface; at least one magnetic track provided on a portion of said indicia receiving surface of said support means; at least one line of non-coded indicia in the form of raised characters provided on a portion of said indicia receiving surface; and means provided in one of said pair of longitudinally extending edge portions for preventing the wedging of the card in the slot of the magnetic reader including: a second pair of transversely extending edge portions provided in said at least one of said pair of longitudinally extending edge portions between said first pair of transversely extending edge portions, and an additional longitudinally extending edge portion disposed between said second pair of transversely extending edge portions, said second pair of transversely extending edge portions and said additional longitudinally extending edge portion defining therebetween a recess for compensating for deformation of the card resulting from providing the card with raised characters, said recess extending substantially over the entire length of the longest line of non-coded indicia.

Claim 6
Dependent Claim
26 words
A magnetic card as defined in claim 4, wherein said at least one line of non-coded indicia is provided in said support closely adjacent said recess.
Claim 7
Dependent Claim
20 words
A magnetic card as defined in claim 5, wherein said recess is only several tenths of a millimeter in depth.
Claim 8
Dependent Claim
32 words
A magnetic card as defined in claim 1, wherein said support means is formed of a plurality of laminated layers, said magnetic track being provided between a pair of said laminated layers.
Claim 9
Dependent Claim
21 words
