Abstract
Abstract The invention relates to a device for preventing unauthorized use of card- or disc-shaped proofs of legitimacy and/or data carriers, such as ATM cards, credit cards and flexible discs, comprising a cover or case-shaped device (1) or the like having at least one pocket or the like adapted to receive at least a portion of at least one card, disc, etc., actuators and control means (4) arranged in said pocket, said control means being adapted to control said actuators and preferably being of the code lock type and comprising one or more means which, when actuated in a certain sequence or in a certain combination, are adapted to control said actuators. The novelty of the invention resides in that said actuators comprise means (17, 20x, 27) which are activatable when an attempt at gaining access is made without proper actuation of said control means and which, in the event of such an attempt at unauthorized access, are adapted to permanently mechanically damage said card, disc etc. and/or the data carried thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A device for preventing unauthorised use of card- or disc-shaped proofs of legitimacy and/or data carriers, such as ATM cards, credit cards and flexible discs, comprising a cover- or case-shaped device (1) or the like which has at least one pocket or the like adapted to receive at least a portion of at least one card, disc etc., actuators and control means (4) arranged in said pocket, said control means being adapted to control said actuators and preferably being of the code lock type and comprising one or more means which, when actuated in a certain sequence or in a certain combination, are adapted to control said actuators, characterized in that said actuators comprise means (17, 20x, 27) which are activatable when an attempt at gaining access is made without proper actuation of said control means, and which, in the event of such an attempt at unauthorised access, are adapted to permanently damage the card, disc etc. and/or the data carried thereon.
Claim 2
Independent Claim
162 words
A device for preventing unauthorised use of card- or disc-shaped proofs of legitimacy and/or data carriers, such as ATM cards, credit cards and flexible discs, comprising a cover- or case-shaped device (1) or the like which has at least one pocket or the like adapted to receive at least a portion of at least one card, disc etc., actuators and control means (4) arranged in said pocket, said control means being adapted to control said actuators and preferably being of the code lock type and comprising one or more means which, when actuated in a certain sequence or in a certain combination, are adapted to control said actuators, characterized in that said actuators comprise means (17, 20x, 27) which are activatable when an attempt at gaining access is made without proper actuation of said control means, and which, in the event of such an attempt at unauthorised access, are adapted to permanently damage the card, disc etc. and/or the data carried thereon.
Claim 3
Dependent Claim
54 words
Device as claimed in claim 1, characterised in that said actuators comprise mechanical means (17) which, in the event of an attempt at access without proper actuation of said operating means, are activatable and which, when such an attempt at unauthorised access is made, are adapted to permanently mechanically damage said card, disc etc.
Claim 4
Dependent Claim
42 words
Device as claimed in claim 1, characterized in that said actuators comprise containers for substances which, in the event of an attempt at unauthorised access, i.e. without preceding proper actuation of said control means, are activatable, or like substances affecting said card.
Claim 5
Dependent Claim
26 words
Device as claimed in claim 3, characterized in that said activatable substances (20x) are pyrotechnical and, under the action of heat, affect said card, disc etc.
Claim 6
Dependent Claim
31 words
Device as claimed in claim 4, characterized in that said activatable pyrotechnical substances (20), under the action of mechanical means (17), are adapted also to mechanically affect said card, disc etc.
Claim 7
Dependent Claim
48 words
Device as claimed in claim 1, characterized in that said actuators comprise at least one magnet or the like adapted, when an attempt at removing said card is made without proper actuation of said control means, to negatively affect the information magnetically stored on said card or disc.
Claim 8
Dependent Claim
31 words
Device as claimed in claim 1, characterised in that said control means are adapted to control electronically operating actuators (27) which, when activated, will damage the information available on said card.
Claim 9
Dependent Claim
24 words
Device as claimed in claim 1, characterized in that said cover- or case-shaped device is adapted to store at least one card, disc etc.
