#CMT# #/CMT# The document has an adhesive label with a flexible sheet (3) whose recto side (30) bears features (73) printed related to the bearer identity. An additional flexible sheet (4) has the reverse side (41) bearing a radio frequency identification (RFID) antenna, and a recto side (40) bearing a non-contact silicon chip (60), connected to the antenna via pads (611). The reverse side (31) of the sheet (3) is fixed to the side (40) to enclose the chip between the sheets, and the side (41) is covered with an adhesive. The sheet (4) has fragilization lines which separate the sheet into two parts. #CMT#USE : #/CMT# Identity and security document e.g. passport, identity card and visa, for storing biometric data. #CMT#ADVANTAGE : #/CMT# The reverse side of the additional sheet is covered with the adhesive which ensures an irreversible bonding and which covers part of the antenna. The antenna is therefore directly in contact with the adhesive and the additional sheet so that any attempt to separate will make part of the antenna to be detached from the sheet and to remain fixed to the adhesive, thus improving the safety by the destruction of the antenna, in case of attempt of separation. The fragilization lines ensure the safety of the antenna while attempting to de-laminate. The reverse side of one sheet is fixed at the recto side of the additional sheet to enclose the non-contact silicon chip between the sheets, thus protecting the chip in a better manner from external constraints. Any attempt to recover the chip requires an internal de-lamination, which involves the destruction of the adhesive label. The antenna spires are far away from the upper side of the label so that the legibility of the label is increased and fine and secured supports can be used for the graphical side. The document avoids the formation of an insulating bridge associated to the antenna. The document permits to implement the `doubles face` technique in order to eliminate the need for specific case for the connection of the chip. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a passport in half-open position. 3 : Flexible sheet 4 : Additional flexible sheet 30, 40 : Recto sides 31, 41 : Reverse sides 60 : Non-contact silicon chip 73 : Features 611 : Pads `(Drawing contains non-English language text)` #CMT#POLYMERS : #/CMT# The sheets can be made of fibers of Teslin(RTM: polyethylene based synthetic medium) and Neobond(RTM: a mixture of cellulosic fibers and textile i.e. polyamide and polyester, fibers) type synthetic material such as polyethylene, polypropylene, polyamide and polyester. |
