Definitions

  • this invention is related to an element for crediting and/or access to electronic terminal equipment which capacity for storing credit and/or access codes is not limited by its physical dimensions. More specifically this invention is related to an element for crediting and/or acess to electronic terminal equipment, said element constisting of a card type substratum having embeded in it and integrated circuit chip, the transferring of data between this card and the electronic terminal equipment being effected by electromagnetic induction.
  • the invention covers also a data registering and reading device intended to transferr data between the above mentioned card and electronic terminal equipment said transferrence not needing physical contact or any displacement, being effected by electromagnetic induction.
  • cards as element of credit and/or access
  • these cards generally containing a fixed code to identify its owner and/or the authorized access and the elements of credit themselves subject to alteration by the machine effecting the reading and charging of the authorized credit, as it happens, for example, with cards to pay the fare for multiple trips in subways, which cards contain a code to identify the authorized type of service, in this case a multiple number of trips, and a plurallity of credits, which are cancelled every time the card is inserted in the imput terminal equipment.
  • the magnetic card due its simplicity and easy of reading/registering, are the more widelly used, not excluding however,the use of other types, such as optical or holographic reading cards, or even a combination of these types.
  • the magnetic card in spite of its easy of registering and reading, has as an inconveniente the fact that the imput equipment must be provided with means to displace said cards or the registering/reading head, to register/read data in the cards, as it happens with a magnetic sound recording tape, requiring the use of displacement mechanisms having mayable parts, usually subject to wear and malfunctioning and requiring frequent maintenance. Besides, such magnetic cards present also the additional inconvenience that the data recorded in them are highelly vulnerable to the action of magnetic fields emanating from permanent magnets, electric motors and transformers, etc. Another inconvenience presented by magnetic cards, when used as credit elements, is the fact that the credit processing substratum is not destroyed after accounting butoonly altered, so that the cards may be repeatedly recorded and evenlually reused dishonestly.
  • optical reading cards in which coding as well as crediting is registered by means of mechanical perforation, due to their simplicity, they may be easily altered, through obstruction of the existing perforations or else the opening of new ones, their use, as of consequence,not being dependable as element of credit, besides requiring, to register as well as to read, mechanical equipment of high complexity and poor reliability requiring expensive maintenance.
  • coding and credit charging are registered as differential reliefs in a stripe, the reading being performad by the identification of the angular differences of a reflected laser beam aimed at the stripe, and the credit charging by erasure of the relief with heat or pressure. So that the laser beam may sweep the stripe lenght the beam or the card must be displaced, requiring a system of high complexity and expert maintenance.
  • the Brasilian Patent N9 7804885 teaches us how the inconveniences described above may be easily avoided through the use of a card containing a plurallity of electronic cells, each one corresponding to a unit of credit which reading and charging is effected by electromagnetic induction and, in accordance with the principles of the invention described in the patent, mentioned above, the credit cells are cancelled after being processed, thus avoiding their restoration, and also permitting the user to identify by visual inspection the number of credits will available.
  • the objective of this invention is to provide an element of credit and/or access which codes storing capacity is not limited by its physical dimensions. It is also the objective of the present invention to provide an element of credit and/or access permitting changes in the number of codes registered without changing the dimensions of the element.

  • an addressing means known as parallel technic may be employed, in which the code combinations constituting the address are transmitted throug a terminal base having as many conductors as are the number of bits forming the combinations, or else the addressing modality known as series technic may be employed, in which the combinations in the address are transmitted through a terminal base having only one conductor, each combination having its begin and end identified by an additional signal, the use of this technic being, in view of its reduced number of external accesses, very suitable to make use of the present invention.
  • the type of card included in this invention is not limited to a particular kind of integrated circuit chip, the integrated eletronic memories and the micro-processeres ' are particularly suitable to the majority of applications, the type of circuit to be chosen being dependent of the level of intelligence required by the application..
  • a registering and reading device which permits to detect the presence of a card and to transmit data between said card and an electronic terminal equipment through the application of an induced signal in the inductive coupling terminals contained in the card, each inducting element being formed by two call wound core bars separated by an air gap and located in the electronic terminal equipment in which the card is introduced by the user, in such a position to permit that each inductive coupling terminal is subjected to the action of a correspondent inducting element without physical contact between them.
  • the registering/ reading device does not require additional movements for ' introduction or extraction of the card, since these movements are manually executed by the card user, the use of electric motors, movable parts or displacement devices being obviated.
