Definitions

  • the invention relates to a security card and a method for its manufacture.
  • Security cards include a wide variety of cards, usually manufactured from a plastics material, which are used to identify or authorise the bearer.
  • One group of security cards is that of transaction cards used in the process of completing a financial transaction and including credit cards, cash cards, debit cards, identification cards and cheque guarantee cards.
  • Other groups include that of pass cards enabling the owner of the card to gain access to a building, service or country and the like and cards enabling the bearer to use vending machines.
  • These cards usually exhibit personalised information characteristic of the bearer, for example the name of the bearer, details relating to a credit or bank account held by the bearer, the date of expiry of the card, and the signature of the bearer.
  • transaction cards may be presented to a retailer who may use the card to imprint the account details onto a sales slip which, in the case of a credit card, the bearer subsequently signs.
  • the retailer is then obliged to ascertain that the signature on the sales slip corresponds with that on the card. No other means is commonly provided to enable the retailer to ensure that the person presenting the card is the rightful bearer of that card.
  • Fraudulent use is possible if the signature can be removed from the card and a new signature is substituted, or alternatively the signature may be forged on a cheque following the example provided on the card.
  • Various means have previously been proposed to prevent tampering with the signature including the addition of reactive chemicals to the strip on which the signature is written, but these are not particularly effective.
  • the forged card When covered with a varnish, the forged card, particularly when presented in a busy retail outlet, is not readily distinguishable from a genuine card.
  • a further method involves the addition of a photographic emulsion to a substrate, usually paper, which is then encapsulated within a clear plastics envelope. This envelope is usually formed from two plastics films which are then laminated together to seal in the photograph and substrate.
  • This card also suffers from a disadvantage that it is often possible to remove the photograph and substitute another, without leaving any easily recognisable sign that the card has been tampered with.
  • a security card comprises a core formed by at least two laminae, one or more indicia characteristic of the card bearer being provided within the core between the laminae, and the or each indicium being detectable through at least one of the laminae.
  • a security card comprises a central core, often of a plastics material, on which indicia characteristic of the card bearer are printed, outer surfaces of the core having overlaminae provided thereon.
  • indicia are provided within the core itself so that anyone attempting to gain access to the indicia would have to destroy the card or leave signs that it had been tampered with.
  • the card bearer such as a photo-image of the card bearer is provided between the core laminae.
  • This may be for example a likeness of the bearer's face.
  • a likeness may be solely provided but alternatively, or additionally, a representation of the bearer's signature may be provided between the core laminae.
  • the indicia may provide one or more alphanumeric characters characteristic of the bearer, or the bearer's name.
  • a security card comprises a core formed by at least two laminae, one or more indicia being provided within the core between the laminae, further indicia duplicating some or all of the indicia between the laminae being provided on a surface of the core, and the or each indicium within the core being detectable through at least one of the laminae.
  • the core will carry on at least one of its outer surfaces conventional information about the bearer, such as his account number and the like and the or each indicium provided within the core may duplicate at least some of the indicia on the outer surface.
  • the security card can be easily checked by comparing the indicia on the surface of the core with the indicia within the core. Even if the indicia within the core is not as clear as that on the core, a sufficient comparison can be made to establish that they are in fact the same.
  • At least one indicium within the core may be duplicated at least once within the core either between the same two core laminae or between different pairs of core laminae where the core comprises more than two laminae.
  • the duplicated indicia may be arranged in alignment with one another so that by viewing the security card, any differences between indicia which should be the same will be fairly easily recognised, but preferably the duplicated indicia are relatively offset to assist comparison.
  • At least one of the duplicated indicia may be reduced in size relatively to' the other or others.
  • the reduced indicium is considerably reduced relatively to the other or others so that it is only detectable with the use of a lens.
  • the non-reduced indicia are detectable and recognisable to the naked eye.
  • the reduced indicium will be provided within the core and the non-reduced indicia on an outer surface of the core.
  • One new feature which we have developed for use with the invention is the inclusion in addition to other indicia of a security character or code solely within the core.
  • the retailer or other person to whom the card is presented must not only record information on the surface of the core but also the character or code within the core which can only be seen by holding the card adjacent to a light source or by some other means.
  • the advantage of this is that it encourages the retailer to look at the other indicia within the core.
  • this security character or code is a single alphabetical or numeric character which may be assigned at random during the manufacturing stage or may relate directly to the security card number, a modulus check number, for example, or may be issued by the bank or other institute issuing the card.
  • the issuing institution can also agree only to honor a transaction involving a security card if the security character is recorded by the retailer.
  • security features which may be incorporated include the use of invisible printing, which is viewable only under ultra-violet light, rainbow printing, and vignette printing. A micro-grounding may also be printed over a photo-image as additional security, or may be printed on an under surface of an overlamina.
  • solvent sensitive inks may be used so that any attempt to delaminate the security card by the use of solvents can be detected since the solvents will react with the inks which will change colour either due to the release of a dye contained within the solvent sensitive ink or due to a direct reaction between the ink and the solvent.
  • Further-security features may be included such as embossing the card surface over a part of the indicia on the surface of the core, and including a security thread in the form of a black line or code.
  • indicia may be provided at the same time within the core.
  • the indicium within the core may normally be provided directly on one or more surfaces of the core laminae, the indicia may be provided on one or more relatively thin laminae sandwiched between the core laminae. These thin laminae may be similar to conventional overlaminae.
  • the laminae of the core is made of a translucent material to enable the or each indicium within the core to be detected. It is particularly convenient, however, if all the core laminae are translucent whereby the or each indicium between the core laminae are visible on transmitting light through the card. In this way, the or each indicium within the core may be visible to the naked eye.
  • the or each translucent lamina may be made from a plastics material such as PVC filled with a sufficient quantity of titanium dioxide such that the lamina is not opaque, as in conventional security cards, but exhibits a degree of translucence.
  • the material of the laminae of the core may be such that one lamina enables the indicia within the core to be detected while the other lamina carries the normally visible indicia and does not enable the indicia within the core to be detected.
  • both laminae allow the indicia within the core to be detected and in this case each indicium within the core may be offset from the corresponding indicium on the surface of the core as previously mentioned.
  • the likeness of the bearer of the card may be a likeness of the head of the bearer and included in thatlikenessmay be a numeral or letter, such as the letter "M" or some other indicium.
  • the likeness will still be recognisable for comparison purposes with the bearer of the card and the included indicia will appear as a shadow.
  • a method of manufacturing a security card comprises providing at least two core laminae; providing one or more indicia characteristic of the bearer of the card between the laminae; and joining the laminae together, the material of at least one lamina being such that the or each indicium is detectable through that lamina.
  • a method of manufacturing a security card comprises providing at least two core laminae; providing one or more indicia between the laminae; providing some or all of the same indicia on an outer surface of one of the laminae; and joining the laminae together, the material of at least one lamina being such that the or each indicium between the laminae is detectable through that lamina.
  • overlaminae may be provided on the outer surfaces of the core.
  • the overlaminae provide protection for any indicia on the outer surface (s) of the core but may also contain security features themselves.
  • the core laminae may have a thickness of between 0.1 and 0.6 mm, while the overlaminae are normally crystal clear and from 0.02 to 0.2 mm in thickness.
  • the laminae may be laminated together at a temperature in the range 120-160°C and at a pressure in the range 200-500 pounds per square inch.
  • an adhesive is introduced between adjacent laminae prior to joining the laminae together.
  • An adhesive could be included between the core laminae and/or between the core laminae and any overlaminae, and/or between adjacent overlaminae.
  • the adhesive may be provided on the laminae by coating such as extrusion, blade coating, or screen printing or by other known methods.
  • Suitable adhesives include those based on polyester, polyamide, and polyurethane resins. These adhesives typically are reactivated by heat and this can be disadvantageous since such reactivation could be carried out in some circumstances in order to tamper with the card. Conveniently therefore thermo-setting adhesives are used.
  • the adhesive is a two part adhesive, one part of the adhesive being coated on one lamina, and the other part of the adhesive being coated on the other lamina, prior to joining the two laminae together.
  • the use of a two part adhesive is advantageous since it cannot be reactivated.
  • the or each indicium provided between the core laminae may be provided on an inner surface of the lamina whose outer surface carries further indicia if that is also provided, or on the inner surface of the other lamina.
  • the or each indicium is provided on a relatively thin lamina, thick core laminae being joined together with the thin lamina carrying indicia sandwiched between them.
  • indicia may be provided between the laminae.
  • One example comprises recording one or more indicia, positioned between the the core laminae, on photographic film (for example 35mm recording film); developing and exposing the film onto a printing plate; printing the or each indicium on a surface of a first core lamina; printing the or each indicium on a surface of a second core lamina; and joining the laminae together with the or each indicium on the first core lamina sandwiched between the core laminae and offset relatively to the or each corresponding indicium on the surface of the second core lamina.
  • the printing plate is used to print the image on a first lamina of the core, a second core lamina is then positioned on the printing press offset with respect to the first core lamina and is printed with the same plate so that the image will be offset with respect to the image on the first lamina.
  • the or each indicium may be recorded directly on paper plate material which is then used to print the or each indicium on the core laminae.
  • an adhesive between the core laminae is particularly useful in that it assists not only in bonding the laminae together but also bonding the ink to the laminae.
  • the method comprises recording one or more indicia, for positioning between the core laminae, on photographic film; developing and exposing the film on a silver halide gelatin photographic emulsion coated on a surface of a first core lamina, exposing the film on a silver halide and gelatin photographic emulsion coated on a surface of a second core lamina; joining the laminae together with the or each indicium on the first core lamina sandwiched between the core laminae and offset from the or each corresponding indicium on the surface of the second core lamina.
  • a sheet of plastics material similar to the core lamina may be coated with a photopolymer, or a photopolymer which has been coated onto a polyester base may be used, the image later being transferred to the laminae used for the manufacture of the core.
  • an adhesive between the core laminae not only assists in bonding the laminae together but also in bonding the light sensitive layer to the laminae which is important when using a photographic emulsion and preferable with photopolymers.
  • the method further comprises including a security code or character at an edge of the indicium or whereby the second core lamina is sufficiently offset relatively to the first core lamina that the security code or character is only provided on the surface of the first core lamina.
  • the security code is solely provided within the core and is not duplicated on an outer surface of the core.
  • this offsetting is generally carried out in any case so that the indicia within the coreare offset from and visible separately from the indicia on the surface of the core and can easily be compared.
  • the security code or character can be provided in the gutter between adjacent images.
  • Other methods for providing indicia between the core laminae may comprise conventional printing techniques, such as litho-printing or screen printing, or electrophotographic techniques such as a xerographic method, or other wellknown methods such as ink jet printing, laser printing or engraving.
  • the indicia may be provided directly on thick core laminae but the core lamina may instead be formed by a relatively thin lamina or laminae which is then positioned between thicker core laminae and/or on the surface of the core.
  • This method is particularly useful with the photographic technique since it is difficult to coat thick core laminae with an emulsion. It is also useful since indicia characteristic of the bearer of the card can be more easily provided on thin laminae while indicia which is relatively invarient from card to card, such as the name of the issuing institution, can be provided directly on the core.
  • the method further comprises generating a likeness of the bearer of the card; modulating the likeness; and recording the modulated likeness on a surface of a lamina of the card, the modulated likeness being such that the original image is still recognisable but has one or more indicia included therein.
  • This method is particularly advantageous since the one or more indicia form part of the likeness itself and it is therefore extremely difficult to reproduce fraudulently.
  • the step of modulating the likeness comprises modifying the density of different parts of the likeness.
  • the recording step may comprise-recording the modulated likeness on a printing plate or photographic film and subsequently applying the recorded likeness the lamina, or alternatively, the modulated likeness may be exposed directly onto light sensitive material provided on the surface of the lamina, for example that surface which will provide an outer surface of the core.
  • Apparatus for modulating the likeness may include a memory, such as a computer memory, in which the likeness is stored in digital form. This may be achieved by dividing the likeness into a number of pixels and coding the likeness according to the degree of lightness or darkness in each pixel.
  • the means for modulating the likeness may comprse means for applying an algorithm to the recorded likeness so that the degree of darkness or lightness in some of the pixels is modified to cause one or more indicia to appear within the likeness.
  • One suitable apparatus is the Lasercomp manufactured by Monotype Corporation of Redhill. This is a laser photo-type setter which provides a memory which can store a digitised likeness. In this case, each pixel corresponds to a, or a portion of a, dot the distribution and area of the dots being initially affected by the lightness or darkness of the original likeness, the distribution and area being changeable in accordance with instructions from a computer program.
  • the method may further comprise forming one of the duplicated indicia reduced in size relatively to the other.
  • the reduced indicium is considerably reduced relatively to the other indicia so that at least one indicium is detectable and recognisable to the naked eye whereas the other is only detectable with the use of a lens.
  • a method for manufacturing a plurality of security cards comprises providing indicia on a surface of the first lamina; providing the same indicia on a surface of a second lamina; registering the two laminae together with the indicia relatively offset; joining the laminae together; and dividing the laminae into the plurality of security cards.
  • the dividing step may comprise a punching operation.
  • This method may include.any of the methods previously outlined but preferably the indicia are initially recorded on photographic film and the film is then developed and exposed onto a light sensitive materials using for example a conventional step and repeat exposing machine such as that manufactured by the Dainippon Screen Manufacturing Company Limited of Japan, in sequence across and down a lamina such that an array of images of the indicia is exposed.
  • a conventional step and repeat exposing machine such as that manufactured by the Dainippon Screen Manufacturing Company Limited of Japan
  • Each set of the indicia will relate to a different bearer.
  • the bearer will provide a photographic likeness of himself which can be attached to an application form which the applicant must sign. Other information can be included on that form such as the card number, date of expiry etc. arranged in the same way as is required on the card and this completed form with the photographic likeness can then be photographed to generate the indicia.

  • the laminae 1, 2 are formed by a translucent, plastics material such as PVC filled with titanium dioxide.
  • the photographs 3, 6 and the signatures 5, 8 may have been provided-on the laminae 1, 2 by means of a conventional printing process or a photographic process in which the surfaces 4, 7 of the core laminae 2, 1 are initially coated with a silver halide gelatin photographic emulsion.

  • other conventional security features are provided (not shown in the drawings) such as a complex printed pattern forming a border 20 to the security card.
  • This character 21 is visible through the core lamina 2 in a similar way to the signature 8 and photograph 6 but requires the security card to be viewed in this way thus ensuring that the security card is checked.
  • the security card bearer presents the security card to a checker who will hold it in front of a light source to enable the duplicate photograph 6 and the duplicate signature 8 to be viewed.
