TARJETA INTELIGENTE CON CONTACTOS SMART CARD WITH CONTACTS
DESCRIPCIÓN DESCRIPTION
Tarjeta inteligente con contactos Smart card with contacts
Objeto de la invención Object of the invention
La invención se refiere al sector de las tarjetas magnéticas y de seguridad, con soporte de informaciones de alta densidad de memoria y un microcircuito. The invention relates to the magnetic and security card sector, with support for high memory density information and a microcircuit.
Se trata en concreto de una tarjeta chip con contactos, en la que se utilizan técnicas de aprovechamiento de energía ("Energy Harvesting") para su alimentación eléctrica, transformando la energía mecánica en eléctrica mediante el uso de un material piezoeléctrico, almacenando posteriormente la energía generada en un condensador (4) dispuesto en la propia tarjeta. In particular, it is a chip card with contacts, in which energy harnessing techniques are used for its power supply, transforming mechanical energy into electrical energy through the use of a piezoelectric material, subsequently storing energy generated in a capacitor (4) arranged in the card itself.
Antecedentes de la invención Background of the invention
Dado el desarrollo de la tecnología se hace necesario un constante avance en el manejo de la información en forma rápida, oportuna y sin límites en demoras o de formatos en papel. De este modo, se hace necesaria la utilización de las nuevas tecnologías aplicadas a las tarjetas inteligentes. Given the development of technology, a constant advance in the management of information is necessary in a fast, timely and unlimited way in delays or paper formats. In this way, the use of new technologies applied to smart cards is necessary.
Las tarjetas inteligentes son tarjetas de plástico, similares en tamaño y otros a las tarjetas de crédito, que llevan estampadas un circuito integrado.
Este circuito integrado puede ser de sólo memoria o contener un microprocesador con un sistema operativo que le permite realizar funciones como almacenar, codificar información o leer y escribir datos. Smart cards are plastic cards, similar in size and others to credit cards, which have an integrated circuit stamped on them. This integrated circuit can be memory only or contain a microprocessor with an operating system that allows you to perform functions such as storing, encoding information or reading and writing data.
La tarjeta inteligente se activa al introducirla en el lector de tarjetas. Los contactos dispuestos en el cuerpo de la tarjeta permiten el intercambio de datos entre el lector y la propia tarjeta, así como el suministro de energía eléctrica para su correcto funcionamiento. Por lo que la tarjeta siempre necesita de un lector que suministre la energía necesaria para operar. The smart card is activated by inserting it into the card reader. The contacts arranged in the card body allow the exchange of data between the reader and the card itself, as well as the supply of electricity for proper operation. So the card always needs a reader that supplies the energy needed to operate.
Tradicionalmente, la única forma de suministrar energía eléctrica de forma autónoma a una tarjeta inteligente ha sido mediante la incorporación de una batería extraplana o mediante una célula solar en el cuerpo de la tarjeta. Es el caso por ejemplo de la tarjeta descrita en la patente EP 0785527, que incluye una unidad de microprocesador para la ejecución de las instrucciones almacenadas en la memoria, una pantalla, para mostrar la información, un teclado para la entrada de datos del usuario, un interfaz para la transferencia de señales entre la tarjeta inteligente y el sistema externo, y una células fotovoltaicas para proporcionar energía a la tarjeta inteligente cuando ésta está expuesta a la luz. Traditionally, the only way to supply electric power autonomously to a smart card has been by incorporating an extra-flat battery or by means of a solar cell in the card body. This is the case, for example, of the card described in patent EP 0785527, which includes a microprocessor unit for executing the instructions stored in the memory, a screen, for displaying the information, a keyboard for user data entry, an interface for the transfer of signals between the smart card and the external system, and a photovoltaic cells to provide power to the smart card when it is exposed to light.
Esto resulta en una serie de inconvenientes como son una duración limitada de la tarjeta debido a la corta duración de las baterías, fragilidad de la solución e incluso problemas medioambientales ocasionados por el deshecho de la tarjeta. This results in a series of drawbacks such as a limited card life due to the short battery life, fragility of the solution and even environmental problems caused by card disposal.
La patente EP 0788636 se refiere a las tarjetas con microchip. Se propone una tarjeta con microchip que puede no tener más que dos contactos
que sirven a la vez para intercambios de información, instrucciones y datos, entre la tarjeta y un lector de tarjeta, y para una alimentación de energía de la tarjeta. Según la solicitud, los contactos de entrada son preferentemente un contacto de reloj, que sirve para la sincronización de los datos e instrucciones, y un contacto de entrada/salida de datos (i/o) que sirve para la transmisión de datos e instrucciones del lector hacia la tarjeta y para la transmisión de datos de la tarjeta hacia el lector. Para la alimentación de energía, un rectificador de doble alternancia, puente de diodos, puede ser colocado entre los dos contactos. La solicitud se refiere también al protocolo de comunicación que permite utilizar solamente dos contactos a la vez que tiene instrucciones similares a las de las tarjetas con microchip convencionales (inicialización de la tarjeta, incremento de dirección de célula de memoria, lectura de la célula, escritura, comparación de un código confidencial). El objetivo de la presente solicitud es solucionar el tema de alimentación autónoma de la tarjeta inteligente, sin necesidad de una dependencia exterior para la tensión de alimentación, utilizando para ello una técnica de aprovechamiento de energía mecánica en energía eléctrica comúnmente conocido como técnicas de "Energy Harvesting" que como bien sabemos es utilizar pequeñas cantidades de energía mecánica y convertirlas en energía eléctrica mediante el uso de un material piezoeléctrico, con el fin de ser utilizada en microcircuitos, ya que estos microcircuitos no requieren de grandes cantidades de energía para su funcionamiento por lo se puede utilizar la energía mecánica aplicada a la tarjeta por el simple movimiento de ella y transformarla a energía eléctrica utilizando un material piezoeléctrico, para luego ser almacenada y distribuida por medio de un condensador plano conformado por las caras de la tarjeta con un dieléctrico adecuado entre estas.

According to the request, the input contacts are preferably a clock contact, which serves to synchronize data and instructions, and a data input / output contact (i / o) that serves to transmit data and instructions from the reader to the card and for the transmission of data from the card to the reader.

Description of the invention
La presente invención trata de dar solución a los problemas expuestos anteriormente, como la duración limitada de la tarjeta por las baterías, o los problemas medioambientales por su deshecho, entre otros. Se trata de aprovechar la energía, transformando la energía mecánica en eléctrica mediante el uso de un material piezoeléctrico. Teniendo en cuenta que el chip microcontrolador incorporado en la tarjeta inteligente está orientado a un bajo consumo eléctrico, esta técnica resulta especialmente adecuada. The present invention seeks to solve the problems set forth above, such as the limited duration of the card for the batteries, or the environmental problems due to its disposal, among others. It is about harnessing energy, transforming mechanical energy into electrical energy through the use of a piezoelectric material. Taking into account that the microcontroller chip incorporated in the smart card is geared towards low power consumption, this technique is especially suitable.
De acuerdo a la presente invención, la energía generada es almacenada en un supercondensador situado en el propio plástico de la tarjeta que permite ir liberando la energía en función de la demanda del microprocesador. According to the present invention, the energy generated is stored in a supercapacitor located in the card's own plastic that allows the energy to be released depending on the microprocessor's demand.
La principal ventaja de la solución propuesta en la eliminación completa de las baterías, con todos los beneficios que eso conlleva, como son un uso ilimitado, la eliminación de los problemas medioambientales derivados del desecho de la tarjeta y otros. The main advantage of the proposed solution in the complete disposal of the batteries, with all the benefits that entails, such as unlimited use, the elimination of environmental problems arising from the disposal of the card and others.
La recarga del supercondensador se produce mediante movimientos de flexión de la tarjeta. The supercapacitor recharging occurs by bending movements of the card.
Para la realización práctica se puede usar un micromódulo de la tarjeta sin contactos, ya que el puente rectificador está incorporado en el propio diseño del microcontrolador lo que facilita la implementación de la solución al no requerir ningún componente externo. For the practical implementation, a contactless card micromodule can be used, since the rectifier bridge is incorporated in the microcontroller design itself, which facilitates the implementation of the solution by not requiring any external component.
La realización del supercondensador se consigue laminando el frontal y el reverso de la superficie de la tarjeta mediante una delgada película de
material piezoeléctrico. Como dieléctrico se usa el propio plástico de la tarjeta, lo que forma un condensador que se conecta a los contactos de alimentación (Vcc) y tierra (Gnd) de la tarjeta inteligente. El material piezoeléctrico se conecta a los puntos destinados a la conexión de la antena. The realization of the supercapacitor is achieved by laminating the front and the back of the card surface by means of a thin film of piezoelectric material. The card's own plastic is used as a dielectric, which forms a capacitor that connects to the power (Vcc) and ground (Gnd) contacts of the smart card. The piezoelectric material is connected to the points intended for the antenna connection.
De este modo, cualquier flexión de la tarjeta produce una pequeña corriente eléctrica AC que es rectificada y almacenada en el supercondensador formado por ambas caras de la tarjeta inteligente. Thus, any flexion of the card produces a small AC electric current that is rectified and stored in the supercapacitor formed by both sides of the smart card.
