Description

Transponder of 125 KHz perfected.

Technical sector

The present invention is related to technologies that are used in the identification of individuals, animals or objects of any kind, proposing a device RFID type of adhesive label that provides some really advantageous constructive and functional characteristics for said application.

State of the art

In the current market there are different types of technologies aimed at the automatic identification of objects, individuals or animals, knowing the biometric systems, the magnetic stripes, voice recognition or codes bars, among others.

Both biometric systems and bands Magnetic, as well as voice recognition, are especially indicated for the identification of animals or individuals, while that barcodes are more used for identification of objects.

Bar codes encode data from a image formed by combinations of bars and spaces that are read by special scanning equipment through which can communicate data to a computer, for which for example in In the case of supermarkets, each item is passed through the scanner equipment to keep track of stock and sales

Currently, they are developing technologies for the identification of objects of any kind, individuals or animals, through rapid data collection automatically, without touch or visual contact, by radio frequency, called RFID, being applicable in areas where which current identification technologies are Poor, as in the case of logistics, the management of Materials, industrial automation, after-sales service, etc.

RFID devices allow consulting, modify and capture useful information in real time in virtually any environment, allowing mobility, resistance to rough use and ability to interact with a suitable Information computing system.

Every RFID system consists of an interrogator or  base system that reads and writes data on devices and of a transponder or transmitter that answers you. The interrogator generates a radio frequency field normally by switching a coil to high frequency, these frequencies being in a range 125 KHz to the ISM (Industrial Scientific and Medical) band 2.4 GHz

The radiofrequency field generates a current electric over a transponder receiving coil so that said current is rectified and feeds the circuit. When the feed reaches a sufficient level, the transponder transmits its data, which are detected by the interrogator as a disturbance of the signal level itself.

Depending on the application you want control there are different formats of RFID devices, such as for example capsules, coins, cards, badges labels adhesives, etc.

Self-adhesive labels are stickers formed by different layers of materials that carry in their inside the RFID device and that can adhere to any surface. The RFID device that contains these items is formed by a printed circuit type antenna, connected to a chip or PCB and operate at a frequency of 13.56 MHz.

With the mentioned devices you can perform for example the identification of the different objects of sale in supermarkets, so that when the customer that Acquires pass by box, you can automatically get the price end of total purchase.

However, despite the fact that the price of mentioned tags with RFID device is only approximately two euros, usually results from an incident too high in relation to the price of the item at which apply, discarding its usual use.

Object of the invention

According to the invention, a sticker type transponder that has characteristics constructive and functional that make it really advantageous for its application, resulting in a reduction in the costs of manufacturing and allowing its use in applications single use identification.

This transponder object of the invention presents in its realization the appearance of a self-adhesive label, incorporating inside an RFID functional module that can be read only or read and write, so that the whole  it comprises an outer covering layer, a functional layer intermediate and a subsequent layer of adhesion.

The outer covering layer can be of paper, plastic or any other material that allows to constitute a flexible and adaptable support to cover the functional set of the RFID functional module. This outer covering layer is provided that is also printable on the face destined to be seen.

The intermediate layer is constituted by a module RFID consisting of an antenna coil and a microchip of operation in frequency ranges between 100 to 150 KHz. The antenna coil has a toroidal shape and is constituted by a determined number of turns of enameled copper wire.

The subsequent layer of adhesion is constituted by an impregnation of adhesive applied on the back side of the covering layer, incorporating a removable protective paper that must be removed for fixation of the device in the place of application.

The three layers mentioned overlap in a set that acquires the appearance of a conventional label, with the benefits of a transponder, resulting in a final product Low cost and easy to manufacture.

Detailed description of the invention

The object of the invention relates to a device used to identify objects without contact, constituting a label type transponder with the appearance of a conventional sticker.

Said transponder presents a set (1) that consists of an outer layer (2) of covering, an intermediate layer (3) that integrates the functional mechanism and an adhesion layer (4) for fixing at the place of application.

The covering layer (2) consists of two corresponding sheets (2.1 and 2.2) of paper, plastic, or any other material that allows to form a flexible support and adaptable, which plates (2.1 and 2.2) come together in confrontation mutual, with fixation by glued together, forming a covering which allows an RFID module to be locked inside. The blade (2.1) of the mentioned set destined to be in the front part provides with a printable external face, to incorporate on it the reasons you want.

The intermediate layer (3) is constituted by a RFID module consisting of a coil (3.1) as an antenna and a microchip or PCB (3.2) operating in a frequency range between 100 and 150 KHz.

The toroidal coil (3.1) consists of a certain number of turns of enameled copper wire (3.3), whose ends are arranged by welding on the microchip (3.2), in which the information that the device for your application.

The information data incorporated in the device are transmitted when it is interrogated by a electronic reading device, which generates a current electric on the coil (3.1) so that it generates energy necessary for the microchip (3.2) to transmit the data that It contains stored.

The adhesion layer (4) is constituted by a impregnation of adhesive incorporated on the outer face of the backsheet (2.2) of the covering layer (2), being arranged on said impregnation a protective paper (5) that is removable and must be removed for fixing the device in the place of application.

The device thus forms an adhesive label intelligent, which can be used to identify any object, its manufacture being realizable with conventional procedures, for example starting from rolls sheet suppliers (2.1 and 2.2), among which includes the intermediate RFID module (3), so that the assembly can be carried out in a continuous process, by juxtaposition of the elements and die cut, applying even at the same time the desired prints on the front sheet (2.1) and the impregnation of the adhesive (4) on the backsheet (2.2).
