The technical field

The present invention relates to access control areas that use contactless media for access to a controlled area, and, in particular, disposable contactless ticket and method of its manufacture.

Prior art

In media for access in areas with controlled access, such as public transport network, such as RATP (Autonomous management of the Paris urban transport) and SNCF (the National society of the Railways of France), is increasingly used so-called “contactless” technology in contrast to the classical contact the media. The latter must be inserted into the reader for making contact to verify the validity of the media. Over time, brush the reader polluted, which often entails the loss of contact, forcing the user to repeat the operation several times, and, as a consequence, leads to a considerable loss of time.

The exchange of information between the contact carrier and the reader is basically performed by remote electromagnetic coupling between the first antenna installed in the contactless data carrier, and a second antenna located in the reader. In addition, the media made an electronic module containing the first antenna, associated with a semiconductor plate or a microchip, which further comprises a radio frequency part (RF), a storage device that stores information intended for transmission to the reader, and the logic necessary to generate the transmitted information and processing the received information.

In the public transport network, there are two groups of users : regular users and occasional users. For the first group contactless electronic card ISO format is the most appropriate solution, since the cost of such cards, divided by the total number of trips made over a long period of time, the result is low for the user. However, for the second group, formed by random users, the price of the card becomes too high, as they are forced to buy a card just for one trip.

Disclosure of inventions

Given the above, one of the objectives of the present invention is to perform a media access in areas with controlled access, such as public transport network, in the form of a single ticket is often biodegradable, with a low cost and at the same time with the same functional parameters, the it and non-contact input card, despite the smaller size.

The present invention is a developing method of manufacturing a disposable contactless ticket having the same functional parameters as contactless input card, despite its reduced size.

Thus, an object of the present invention is a ticket that allows access to an area with controlled access at its contactless presentation to the reader access to the zone having the format Edmonson and paper containing body having two sides with a protective coating. In the paper the body of the ticket is made through the socket, which is an electronic module that contains an integrated chip and an antenna formed of at least one revolution, made by printing stencil paint from a silver powder in the polymerizable composition before curing by heat treatment.

Another object of the present invention is a method of manufacturing a contactless tickets, which consists in the preparation of the canvas or multi-row strips of a width corresponding to several values of the width of the ticket, running the cloth through sockets, designed for the installation of the electronic module of tickets, the cutting of fabric into several single strips, each of Kotor which x corresponds to a single roll tickets and consistent imposition on each side, beginning with the first layer of protective coating, and then the second layer of protective coating after installation of the electronic modules in the slot.

In accordance with one of the distinguishing features of the invention on the electronic module in the setup of an integrated circuit installing the cover, having a thickness equal to the thickness of the IC chip and containing a through slot, with subsequent processing of the electronic module with a lid using hot lamination to reduce the resistance of the antenna.

Detailed description of embodiments of the invention

Figure 1 shows the entrance ticket 10 for access to the area with controlled access, such as network metro RATP. The ticket includes a housing 12 Edmonson format 67 mm ×30 mm and an electronic module 14 containing electronic funds necessary for the user presenting the ticket to the appropriate reader to gain access to the zone, for example to the hole automatically opening doors. The reverse side of the housing 12 ticket includes printed information, such as labels, logos (RATP), alphanumeric information, bar codes, etc.

Shown in figure 2 the body of the ticket has a Central layer of paper of a thickness of about 0.5 mm and two thin coating layer on one side 18 and on the other hand 20, made of paper or plastic, such as polyester or polyvinyl chloride, of a thickness of from 0.03 mm to 0.05 mm, the Total thickness of the body of the ticket mainly is 0,560 mm to 0,640 mm or less.

Posted in through the slot of the electronic module 14 is installed between the two layers of the protective coating 18 and 20.

Electronic module, shown in figure 3, includes a substrate made of b the sorcerers or plastic, thickness from 0.08 mm to 0.15 mm, on which the chip or the chip 22 and the antenna 24. Chip is designed to handle electromagnetic signal with a frequency of 13.56 MHz, radiated by the reader and received by antenna 24, and transfer the information stored in the integrated circuit 22 and intended to control access to an area with controlled access by modulation of electromagnetic signal frequency of 847 kHz, used as a carrier.

The antenna 24 is a spiral, made in the form of a square with sides 19 mm and containing at least one stage, preferably 6-10 coils, with the coils may have a square or round shape; the two ends of the spiral are connected with the IC chip 22 with terminals 26 and 28. It should be noted that the antenna 24 has an inductance with a value that allows it to produce a circuit that is resonant with the input capacitor of an integrated circuit.

The manufacture of the antenna is an important aspect of the invention, as it allows you to get a ticket with a lower cost. Manufacturer of antennas based on the technology of screen printing and includes the printing of turns of the antenna on a dielectric substrate which serves as the substrate of the antenna, preferably made of boom and or plastic, with the help of paint, consisting of a fine powder of silver, placed in the polymerizable composition and the solvent. After drying and heat treatment receive conductive spiral shown in figure 3 and formed of silver in the polymerizable composition. After that perpendicular coils put a layer 25 of the dielectric ink. After the heat treatment, paint type conductive strip 27, which is connected to the end 29 of the antenna and the connecting terminal 28, which provides electrical connection with the IC chip, while the second connection is carried out by means of terminals 26. It should be noted that the value of the inductance of the antenna 24 is determined by the width of the forming of the conductor, the distance between the coils and the number of coils.

The sequence of antennas can be made on the strip or tape the antenna substrate by repeating the above operations screen printing. In the future, in the center of each antenna in place an integrated chip, as shown in figure 3, the latter may be connected with the ends of the antenna using a conductive adhesive according to a preferred variant implementation, and by soldering. At the final stage, the strip is cut with electronic modules.

However, before cutting the electronic module within this is of the first invention fulfill one important operation. As can be seen from figure 4, each electronic module 14 includes a substrate 15 on which the stencil method is applied to the antenna 24 and which establish the integrated circuit or microchip 22. If the thickness of the antenna 24 can be neglected, then on another case with a microchip, which has a certain thickness. So a paper or plastic cover 21 mounted on each module before or after cutting the strips. The specified cover has a thickness slightly larger than the thickness of the microchip, and includes a through slot 23 with dimensions slightly larger than the dimensions of the microchip to install it in the slot. Thus, after fitting the cover, the module has an almost uniform thickness (except for the area of the microchip, where the thickness has a somewhat lower value), thereby avoiding the formation of cavities around the microchip after applying a layer of protective coating.

Finally, in the framework of the present invention perform the basic operation hot lamination, which significantly improves the characteristics of the antenna. The overriding objective is to reduce the resistance of the antenna, providing her current maximum power that allows you to achieve maximum radiation power by using the inductance of the antenna. Found that this reduction in resistance is achieved when the impact pressure at to 120 kg/cm 2and basically when exposed to a temperature of preferably from 80 to 170°, that is, through the hot lamination.

A method of manufacturing a ticket starts with the formation of a cloth or multi-row strips of 30 tickets, as shown in figure 5. This paper strip 32 of the desired thickness and width, equal to 10 times the width of the ticket (the width can be different) is removed from the reel 34 and is poured in the molding block 36, in which the paper strip 32 is perforated with receiving holes facing on both sides and intended for mounting electronic modules, and optionally at it from two sides put print. Unit 36 performs the cutting blade 32 10 strips across the width of the ticket, which retracted into rolls of tickets (not shown in the drawing).

The next step, shown in Fig.6, consists of applying a layer of protective coating. With this purpose the strip 40 of paper or plastic (polyester, polyvinyl chloride or other plastic), described above, which is supplied from a roll 42 and has a width equal to twice the width of the tickets, with the ability to cover both sides of the body of the ticket. Served with a roll 42 of the strip 40 is a layer coating consisting of a layer of adhesive substance and a thin layer of silicone paper.

The strip 40 is fed to the cutter 44, in which silicon is the second paper is cut so so after passing over the roller 48 has been removed strip of silicone paper 46 with half of the strip 40. After removing the silicone paper coating layer has an adhesive side of 50, then as part of the adjacent strips 52 remains protected by a silicone paper. After that, the adhesive side 50 is superimposed strip of housings 54 tickets supplied from the roll 56.

The next operation consists in the installation of electronic modules, made in the form, as shown in figure 4, in nests made in the band of the corps of tickets. It should be noted that the retention in the socket module provides adhesive layer provided on the strip of cover 50. In addition, the electronic module cover is independent in relation to the rest of the ticket and has no special axis positioning. It can be installed in the socket in any position, there are 8 possible positions. This feature is interesting because it does not require careful positioning process modules and, therefore, has a low cost. In addition, the consolidation module does not require bonding.

Finally, after removing the layer of silicone paper is part of the coating layer 52 is bent and placed on a strip 54 of the buildings of tickets.

It should be noted that the described method is preferred, however, as the coating layers can also COI is lesofat two separate lanes instead of one, which bend and place the strip of tickets. In addition, you can also apply the gluing layer of the coating on the body of the ticket by hot lamination, instead of just sticking with conventional adhesive.

The above-described contactless ticket has several significant advantages. First of all it is a low cost thanks to low-cost methods of manufacture and use of materials that reduce production costs compared to the contactless card, however, it retains all the functional parameters of such cards. He is also biodegradable, so as for it making use of a paper substrate, and it is the most significant, because we are talking about a single ticket, which is usually discarded after the first use.
