IDENTITY BOOKLET WITH A RADIO FREQUENCY IDENTIFICATION DEVICE
FIELD OF THE INVENTION This invention relates to identity cards such as passports and refers in particular to an identity book with an identification device or radiofrequency. BACKGROUND OF THE INVENTION Non-Contact Radio Frequency Identification Devices (RFIDs) are most often used to identify people moving in controlled access areas or in transit from one area to another. A non-contact RFID is a device composed of an antenna and a chip connected to the terminals of the antenna. The chip is generally not energized and receives its energy by an electromagnetic coupling between the reader antenna and the RFID antenna, information is exchanged between the RFID and the reader and particularly information stored on the chip that relates to the identity of the owner of the RFID. object on which the RFID is located and to authorize (him / her) to enter a controlled access zone. In this way passports can include RFID to identify the owner Jel passport. The memory of the chip
Ref. -.173037
It contains information such as the identity of the owner of the passport, his / her country of origin, his / her nationality, visas of the different countries visited, dates of entry, restrictions of movements, etc. Such a passport is described in U.S. Patent No. 5,528,222 and in the World Patent Application WO / 00/26856. In these documents, the RFID is integrated in the upper part of the passport cover. This is generally inserted between the reinforced cover and the guard sheet of the passport page block, which is laminated to the back of the upper part of the reinforced cover. Unfortunately, it is relatively easy for a fraudster individual to try to forge such a passport and make a forged passport with it. The individual fraudster simply needs to remove the guard sheet to access the RFID already, either replace the cover with a new cover including another RFID, or simply replace the chip with another chip so that the information provided by the RFID corresponds to the information contained in the falsified passport. SUMMARY OF THE INVENTION This is the reason why the purpose of the invention is to provide an identity book such as a passport using a device -d. identity by
radio frequency in which the antenna is installed in such a way that it is destroyed if an attempt is made to falsify the notebook. The object of the invention is in this way - an identity book, particularly a passport, which includes a reinforced paper cover composed of an upper and lower cover, an inner block of sheets whose upper and lower guard leaves are laminated with the rear of the upper cover and with the front of the lower cover respectively and a radio frequency identification (RFID) device composed of a chip and an antenna connected to the terminals of the chip, with at least a part of the RFID that is inserted between the upper cover and the upper guard sheet or between the lower cover and the lower guard sheet. The antenna includes a first part of the antenna placed on the surface - of the upper and / or lower cover - designed to be laminated with
. the corresponding guard sheet and a second part of the
_ Antenna placed on the surface of the. upper and / or lower guard blade designed to be laminated with the corresponding cover, the first and second parts of the antenna are connected to constitute the antenna when the guard leaves are laminated with the covers.

DETAILED DESCRIPTION OF THE INVENTION In accordance with a first embodiment of the invention, the first part of the antenna 10 includes the chip 12 that is in the rear part of the lower cover of the cover 14 of an identity card such or a passport illustrated in Figure 1A. The back of the upper cover 16 does not have an antenna. It should be noted that the first part of the antenna 10 may be a metal band glued onto the page but it is preferable to secure the antenna with a deposited screen of ink containing metallic particles such as silver. The second part of the antenna 18 illustrated in Figure IB is fixed, preferably by silk-screen printing mentioned above, on the back of the lower guard leaf 2 0 of the block of pages of the identity document (FIG. for this reason, it is represented with dotted lines on the figure) when the upper guard blade 22 of the leaf block does not include an antenna. Assuming that the booklet is a passport to which the invention preferably refers, the manufacturing method consists in manufacturing the interior pages of the block with the use of a safety rope to connect them to one another. Afterwards, the guard sheets are '
laminated on the covers, the guard sheet 22, is laminated with the upper cover 16 while the lower guard sheet 20 is laminated with the lower cover 14. As illustrated in Figure 2, the first part of the antenna 10 and the second part of the antenna 18 were respectively placed on the lower cover 14 and the guard sheet 20 in such a way that, at the time of rolling, the end 24 of the first part of the antenna 10 is connected to the end 28 of the second part of the antenna 18, and the end 26 of the first part of the antenna is connected to the end 30 of the second part of the antenna 18. The connection between the ends of the first part of the antenna 10 and the ends of the second part of the antenna 18 can be realized simply by overlapping two small portions of the antenna located at the ends. Such overlap is sufficient to ensure contact. Even a partial contact or a lack of contact is sufficient, as long as the connection is fundamentally capacitive. It should be noted that the capacitance value is not very involved and in no way disturbs the frequency tuning of the antenna (usually 13.5 * 6 MHz). The connection can also be made by placing both ends of one of the parts of the antenna, for example the first part, a drop of glue in the form of a -button
created with conductive epoxy resin. By assuming that an individual fraudster tries to remove the guard leaves in order to falsify the passport, he / she will necessarily separate the two parts of the antenna and thus prevent any subsequent use of the cover as well as the block of pages indoors, unless he / she deposits the missing part of the antenna by screen printing, which is not easy. According to a second embodiment illustrated in Figures 3A, 3B and 4, a part of the antenna is placed on the two covers and thus overlaps the fold located at the intersection of the two covers. Thus, the first antenna portion 40 comprising the chip 42 includes a portion on the front of the lower cover 44 as well as a portion on the back of the upper cover 46. ' The second part of the antenna is located completely on the front of the upper guard sheet 52 of the block of passport pages (this is therefore represented with dotted lines in Figure 3B) while there is not something on the back of the lower guard blade 50. It should be noted that, as in the previous embodiment, the antenna may be a metallic band but it is preferable for the antenna to be made with a deposited screen of conductive ink. The conductive ink used is preferably a polymer ink loaded with elements
conductives such as silver, gold, copper and coal. The material used in the screen printing of the antenna can also be a flexible material such as a conductive polymer. It is also possible to form a flexible connection at the location where the antenna overlaps the fold of the book by adding conductive material such as epoxy resin loaded with silver or conductive elements on the antenna at the fold location of the book for the purpose of making the flexible antenna so that it does not break. When the guard sheets 50 and 52 are laminated on the covers 44 and 46, the end 54 of the first, part of the antenna 40 is connected to the end 58 of the second part of the antenna 48 and the end 56 of the first part of the antenna 40 is connected to the end 60 of the second part of the antenna 48. As in the previous case the connection can be made by simple contacts caused by the overlap between the portions of the two parts of the antenna or by means of a conductive epoxy resin. The second modality presents an essential characteristic that does not exist in the. first modality. Additionally, in the first mode, the antenna remains flat whether the passport remains open or closed, and thus always plays its role as an antenna. In the second embodiment, the antenna is folded when; the passport
it is closed and so in this case it is not operational. Consequently, the passport can only be read if it is open and presented in front of a reader, considering that it can not be read in the closed position. Thus it can never be read without the knowledge of its owner when it is inside his / her pocket or bag, which represents an indispensable security feature. However, in accordance with the first embodiment, assuming that the identity book is a passport to which the invention refers, it is an advantage for screen printing, on the last page of the block comprising the central pages of the passport, a screen flat against the RFID composed of the two parts of the antenna 10 and 18 and the chip 42 when the passport is closed. This screen is preferably fixed on, the entire surface of the page but may be limited to a rectangle whose surface area includes the surface area defined by the two parts of the antenna 10 and 18. The screen is a screen printed with conductive ink or a conductive polymer and is made either of a uniform layer or a grid or a grid pattern whose width of the lines or squares is of the order of a few millimeters and preferably equal to one millimeter. So, when the passport is closed, even if the antenna remains flat, there can be no flow through
This is because the screen plays the role of magnetic protection. Since the antenna does not play its role anymore as one. antenna, the chip does not receive energy and the passport: it can not be read by the reader in the closed position. Continuing not to mention that the two modalities that have been described are not restrictive and that each part of the antenna can be placed partially or completely on the upper and / or lower cover or on the upper guard sheet and / or lower, the only condition is that both parts of the antenna must be connected when the two guard leaves are laminated with the two covers. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
