Anti-intrusion device for use in data reading/writing system, has flange and slug pivoting dummy pad when upper portion is laterally displaced with respect to lower portion to ensure interruption of electrical connection between strips

摘要

#CMT# #/CMT# The device has a case (11) including an upper portion (14) that is fixed to a lower portion (12) in a normal usage position. The case has a dummy pad (30) with a conductive portion (32) that electrically connects two metallic strips (34, 36) in the normal usage position. The upper portion has a flange and a slug pivoting the pad when the upper portion of the case is laterally displaced with respect to the lower portion of the case to ensure interruption of electrical connection between the strips. #CMT#USE : #/CMT# Used in a data reading/writing system for reading or writing data on a chip card and a magnetic card, and for realizing operation of payment, to protect an object e.g. electronic circuit, contained in a case (Claimed). #CMT#ADVANTAGE : #/CMT# The upper portion has the flange and the slug that pivot the movable element when the upper portion of the case is laterally displaced with respect to the lower portion of the case to ensure interruption of electrical connection between the metallic strips, thus preventing the access to the objects or to information contained in the case, and hence effectively protecting the objects against the attempted intrusion of the case. The device has reduced encumbrance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a data reading/writing system. 11 : Case 12 : Lower portion 14 : Upper portion 30 : Dummy pad 32 : Conductive portion 34, 36 : Metallic strips.
