FR2889883A1 - Folder-like anti-code device for bank card, has front and two lateral flaps vertical to central flap in operation state, where all flaps made of cardboard paper have sizes based on bank notes, bank note dispenser and bank card apparatus - Google Patents

Abstract

The device has a central flap, a front flap and two lateral flaps, where the central flap has an opening in the middle, and the front and lateral flaps are vertical to the central flap in operation state. All the flaps made of cardboard paper have determined dimensions calculated according to current bank notes, bank note dispenser configuration and bank card apparatus. The flaps are also dimensioned based on the conjugation of different constraints such as the anatomy of the skull, the physiology of the eye, and laws of the physics of the optics.

Description

Description

  Advertising medium and optical device to prevent the copying of a code: the Anti-Code.

  I) Indication of the technical field of the invention.

  The technical field of this invention is twofold.

  1 / Advertising: as a new mass-market advertising medium.

  2 / Bank cards: by protecting the bank codes, in particular, prying eyes or hidden cameras, but more generally by protecting all codes that are typing (access of buildings, safes, computers etc.).

  This invention, conveyed as a new advertising medium, actually comes in the field of personal protection, but more specifically in the field of bank secrecy protection in correlation with the current widespread use of credit cards. It is therefore an invention with a dual purpose: advertising and protection.

  One carries the other, and conversely, to ensure the success of this invention.

  For added security, many countries add a code number to the credit card number. Thus in case of loss or theft the lack of knowledge of the bank code still protects. But the knowledge of these two elements allows forgers to freely debit the account of the unfortunate owner. The most serious is that it is done without his knowledge. Indeed, in case of loss or theft, it is still possible to realize early enough and make an immediate opposition and thus limit the damage, but, and this is the trick of counterfeiters, the great art is only to copy the number of the card and the code.

  In less time than it takes to say, some in the world a new card is made, it's a perfect clone. The withdrawals can begin, they are done in a few days, and it is only by the exorbitant bank statements that the owner learns his misfortune. It is then very late to block the account.

  Everyone knows this is a very unpleasant adventure, but fortunately the 30 insurances, despite their costs, will be of great help.

  The system I propose to describe can only be adopted by the Bankers if it is infallible and allows them to no longer be insured. This so assured will be analyzed at length. It is also necessary that this system, besides its imperative infallibility, be much cheaper than the insurance premiums and be of a very simple and very fast use.

  This invention is based on the anatomy of the skull of man and on the elementary knowledge of the physiology of the eye, so it is not surprising that it is a doctor who deposits this invention.

  II) Indication of the state of the prior art highlighting the technical problem.

  State of the art: Type your code away from prying eyes, this is the essence of the current protection technique when typing a bank code. There is added on three sides of the keyboard a small vertical relief of two centimeters in height. How to accurately steer your index finger on the right touch while looking, left, right, back, forward and why not up? This famous phrase is inscribed on all the apparatus, it is of a desperate intelligence. The worst thing is that even the most honest man looks at the keyboard in the hands of the other, and this instinctively, in spite of himself. This is an irresistible attraction, incomprehensible, very real, but that everyone denies of course. It may be to better indispose the neighbor. But what is only an innocent little game for everyone is a very skillful teleological exercise for others.

  Recently, in some large car parks, in Marseilles in particular, at the level of crates, there is an optical protection device, or at least one device that would want to be optical protection. It is an imposing metal system that hides the keyboard in an almost vertical position. It's an open box up and down. The hand slips from underneath and the face goes up. One sees there, in the darkness and at a distance too close for a correct reading, his hand and the keyboard. This is the best system that can exist to slide a tiny camera. The system is so imposing, so surprising, so complex, so little enlightened that it is impossible for anyone who could possibly see a little more relief to be wary of it. Currently cameras can be the size of a big capsule.

  Another highly publicized protection system is: fingerprints. The code is replaced by fingerprints.

  The pinnacle of code protection technology is% retinal footprint. Again the code is replaced by the single retinal footprint for each of us.

  A word from / to subcutaneous flea. It can be easily placed as a hormonal implant. It is an excellent solution to not lose or steal your credit card, identity card, passport, driver's license, registration card or Vitale card. But the problem of the code remains intact and the number of the card is no mystery on the internet in particular.

  The technical problem: Just obtain the number of a bank card and its code to reproduce it in an infinite number of copies.

So you have to find a parade.

  It is possible to solve this problem of fraud very simply without using high technology.

  III) Presentation of the invention. Preamble: The proliferation of credit card frauds has two perverse effects.

  On the one hand, the insurance premiums are higher and higher.

  On the other hand, too many consumers shocked by these widely publicized frauds are refusing, for fear, to adopt this mode of payment, yet so practical.

  These are hundreds of millions of bank card transactions that are daily insecure.

  I will be presenting a new mass-market advertising medium that is useful as an optical system for protection against prying eyes or hidden cameras when entering a code. Like car locks, it will be a code lock. It will be an advertising anticode. We will call it for the convenience of the description Anti-Code.

  Technical means to implement to achieve the desired result of the invention. Generally speaking, what is needed to manufacture the AntiCode is found in all printers: A slightly hard-bound paper surface of A4 size. Its tactile qualities, rough, silky, metallized, plasticized etc., are not to neglect, they will have a certain psychological impact.

  É A system for slightly grooving the card stock for easy folding. A system for printing photos and / or advertising texts.

  A cardboard sheet cutting system with the right dimensions. In addition, there is a need for a 20mm orifice, approximately at the center: chisel or punch.

  É An automated system to fold these sheets of paper a little rigid to the dimensions of a ticket of 50.

  For cash dispensers or fuel pumps it is necessary: That the machine delivers, through the ticket slot for the bank dispensers or through the invoice receipt slot for the fuel pumps and possibly the cash dispensers. bank, this Anti-Code to the introduction of the bank card by a simple electric mechanism.

  Whether ambient lighting is adequate, or that the keyboard is illuminated or even better than the keys themselves are illuminated.

  For tradesmen, craftsmen, liberal professions, restaurants, cinemas, supermarkets, etc. it is necessary: É That they put at the disposal of their customers this Anti-Code beside their credit card machine.

  Same as before for lighting.

  What you do not need: Do not change anything else on current computer or electronic systems.

  Banks or fuel distributors by credit cards will have only a small distributor of Anti-Codes to add. Rather than the ticket slot, the banks will certainly use the slot that currently delivers the tickets, to issue the Anti-Code since its dimensions are those of a ticket of 50 or a note of another currency whose dimensions are close to a banknote of 50 C. The facades of bank distributors will remain unchanged and will not be mobilized. The modifications will be done at the back of the dispenser.

  There are currently stacks of 10, 20, and 50 notes at the back of the visible facades of the dispensers. There will be one more stack, the stack of Anti-Codes. It is only an electrical contact that will cause the expulsion of the Anti-Code outside the distributor at the introduction of the bank card. An identical mechanism, but necessarily simpler, will be installed on fuel dispensers. The expulsion of the AntiCode will also be done with the introduction of the bank card but by the slot with receipt of invoices.

  Anyone who currently has a simple credit card keyboard will not change. Supermarkets, SMEs, traders, liberal professions etc. will not change anything at their facilities. They will not have to invest huge amounts of money in fingerprint or retinal recognition systems. They will simply have, next to their device, their stack of AntiCodes Advertising and everyone will use naturally; it's free. If the device is not fixed, at a restaurant for example, the device will be brought on a tray, under the device there will be the Free Advertising Code and the addition of course.

Description proper:

  A slightly hardened paper surface of A4 size on which is cut the surface shown in Figure 6 [Plate 6/10]. That is a surface of 191mm on 254mm. The corners A and B are cut each with a square surface of 50mm on each side. A right triangle, 2mm for the smallest side, is amputated at the four corners A, B, C, D. Two notches are cut, in the shape of any triangles, from points E and F, with the smallest equal side at 2mm. This determines two flaps G and H of trapezoidal shape of 50mm of height and 71mm of base on 37mm. The rectangular surface ABCD measures 154mm on 141mm. 154mm, or (77mm x 2), represents two widths of a 50 note. 141mm represents the length of a 50 note. These measures were taken according to a teleological reasoning as we will see.

  This ABCD surface is bordered on three sides by the following slightly trapezoidal surfaces of 50mm height: ABIJ, then ACNK and BbML. A 20mm diameter hole is drilled on the ABCD surface. Its center is 77mm BD and AC and 50mm AB. Surface AIJBMLDCKN represents the spread invention, i.e. Anti-Code. This surface is grooved so that it can be easily bent along the following lines: AB. BD. DC. IT. and OP. EF.

  When the three surfaces ABIJ, ACNK and BDML are folded perpendicularly to the surface ABbC I'Anti-Code appears in its functional form as shown in Figure 7 [Plate 7/10] and [Fig 10. Board 10/10]. in this case, if the consumer is right-handed, the flap G is folded on a plane parallel to the surface ABbC and beneath this surface. If it is left-handed it will be the flap H and in this case the flap G will be perpendicular to the surface ABbC.

  When the three border surfaces: ABIJ, ACNK and BDML are folded on the plane parallel to the surface ABbC and beneath this surface and if the assembly is folded along the line OP, the Anti-Code appears according to FIG. 8/10] to the dimensions of a banknote of 50 according to the surface RBbP. It is under these dimensions that it will be issued by the distributors of banknotes or the credit card devices of the fuel distributors for example. He will be able to keep himself in a current portfolio.

  If the consumer wants to keep it in a small wallet, it will fold easily according to the QF line and in this case the Anti-Code will look like Figure 9 [Plate 9/10] according to the surface RBFQ.

  The values in Figure 6 [Plate 6 / 10J are not arbitrary.

  They are derived from the visual fields of Fig 4 [Plate 4/10] and its enlargement [Fig 5. Board 5/10], and this for the ideal viewing distance of 400mm according to ophthalmologists. All other values derive from this first postulate. The second postulate is to take the 50 note as a reference ticket. Thus with these two postulates and taking into account the volume occupied by an average adult man's hand the experiment advises to place the ABbC surface according to the figure 10 [Plate 10/10] parallel and 80mm of the plane of the keyboard of the machine to Bank cards; this is the third postulate. It follows from Figure 4 and Figure 5 that it is necessary for the Anti-Code system to be infallible against any prying eyes or covert cameras that the borders represented by the ABIJ, ACNK and BDML surfaces are 50mm wide.

  Let's summarize: 1 postulate: 400mm for the best viewing distance. [Plate 4/10]. 2 postulate: 77mm and 141mm for the dimensions, ie those of a 50 C note. 30 [Plate 6/10 and 8/10] 3 postulate: 80mm to place the hand between the Anti-Code and the keyboard. [Figs 4 and 5].

  Consequences of these postulates: By changing one, two or all three postulates the dimensions of the anti-Code will change.

  Why did I choose these values for these three postulates? Why this variation between 400mm and 330mm for the optimal viewing distance? Because ophthalmologists believe that it varies between these two values. Why did I choose 400mm? Because it is at this distance that ophthalmologists correct presbyopes in general. be this distance and given the visual field plots for a subject located at 400mm from the keyboard, it follows that the hole of the ABDC surface must be about 20mm in diameter for 10mm / 10mm keys.

  It is of course possible to make a little bigger or a little smaller but it is necessary to know that obviously and always according to the visual field layout a reduction of this value would make the use difficult and an increase would weaken the infallibility of the system.

  Why did I choose the 50 note as a reference ticket for its size? Because it's a common ticket. One could just as easily create an Anti-Code on the basis of a 20-note or use another currency, while remaining in notes of this order of magnitude. The Anti-Code would see its dimensions dictated by these choices and its dimensions would always flow from the visual fields of Figures 4 and 5. It is a quality of this invention to be able to adapt on the one hand to all currencies and secondly to the optimum distance of vision that a particular country would like to adopt.

  Why did I choose 80mm between the keyboard and the Anti-Code? This value comes from experimentation. Obviously for a normal hand of an adult man, 80mm is largely sufficient for the lower part of a hand, that is to say the fingers and half of the metacarpus, move easily to hit a small keyboard. This value can therefore vary somewhat in more or less.

  Three remarks: Regarding the dimensions of the bank card devices of the shops. The keyboard (j) approximately 9Omm wide may vary somewhat.

  2 Borders (n) of approximately 20mm may vary somewhat from back to front.

  3 According to [Plate 5/10], and for the assumptions we have adopted, the value of the borders of the Anti-Code should be 47.3mm.

  Thus, considering the two previous variables, a value of 5Omm for the borders of the Anti-Code, instead of 47.3mm, provides security and resolves the possible small problem.

  With regard to the anti-codes eviction slot: For cash dispensers the elegant solution is to use the current ticket slot to evict the anti-code at the introduction of the bank card. We pointed out that this expulsion could be done through the ticket slot. But of course, it is also possible to do differently and at least in two ways: either by creating an additional 3 slot only for the expulsion of Anti-Codes, or by placing an Anti-Codes dispenser on the outside. , which would significantly alter the facade. Same analysis of course for fuel distributors.

  As for the dual function, advertising and protection of the Anti-Code: It is worn just as much by both sides of the AntiCode.

  IV) Understanding of the technical solution which is brought to the technical problem posed: The description of my invention is as we have just seen it very simple. The understanding of its effectiveness requires in part knowledge of anatomy of the skull [Plates 1/10, 2/10 and 3/10], in physiology of the eye and in optics physics [Plates 4/10 and 5 / 10]. The simplicity of my invention is the result of the combination of all this knowledge. But that the reader is reassured, it will not be necessary to leave the encyclopaedias of anatomy, physiology of the eye or optics. The great trick is simply to draw from it only a few fundamental pieces of information that combine together give this fruit: the Anti-Code.

  Some analogies are needed, I think, to the understanding of the system: When an ENT specialist has to learn how his Boss grafts a tympanum, the operating theater must have a whole system of optics based on prisms and mirrors for that he too can see the operating area. When a doctor examines a tympanum with his headlamp and auricular speculum he is the only one to see the tympanum. This is very embarrassing especially when he would like to show it to the mother to better explain what should be done. But it's impossible even plays against cheek. Decidedly Newton is right, the light rays propagate effectively in perfect straight lines [Plates 4/10 and 5/10]. He can sometimes show him the tonsils of his child if he wants to open his mouth wide. So by varying the opening of the mouth we can or not see two. Hence the idea of reproducing the same conditions, or almost, so that this impossibility of seeing two serve the good cause that concerns us, without however going to ask consumers the Dexterity of the Doctor. Thus analogy by analogy the invention is born and understood. The key (k) to reach precisely is the eardrum. Their dimensions are very similar. The distance of vision is the same, it is the distance of the best vision (400mm). The axes of vision are the same. The orifice of the surface (m) is the orifice of the external auditory canal. The Skull of the Doctor [Plates 1/10, 2/10 and 3/10] is the same as that of the consumer lambda. End of analogies.

  A little anatomy of the skull is, I think, essential: (Planks 1/10, 2/10 and 3/10). The essential The human skull is less wide in the eyes (110mm) than in the ears (160mm). Children who are old enough to walk know it well, they can pass through the bars of a balcony ramp, eyes but not ears. The value of the spacing bars has not been imposed for nothing ... The reader can switch to a little physiology of% eye next page ..

  But for the purposes of the patent I must say a little more: Indeed, why even plays cheek, tempe against tempe it is impossible to see two? This is due first to the morphology of the skull and to the position of the eyes in relation to the most prominent elements of the skull and then to the optical consequences of two skulls playing cheek. Nobody sees the world from the same angle at the same time. And for each person, at the same moment, the left eye sees a world different from the one seen by the right eye. The pupils [Plate 4/10. (a) and (b)] and [Plate 2/10] are on average spaced 62mm apart.

  The distance between the two lateral bony edges of the orbits [Plates 1/10, 2/10 and 4/10. (c) and (d)], that is, the zygomatic processes [Plate 1/10. (2) (see summary)], is on average 11Omm [Plate 2/10]. Thus the left eye of the mother is at best 48mm from the right eye of the Doctor it follows that the two cones of vision of the Doctor and the mother are not the same.

  It remains to be determined, but we will return, the diameter of the central hole of the screen surface, Anti-Code, [Plates 4/10 (m) and 5/10. (m) and 6/10] so that it is favorable only to one. Everything is here. Let's finish with the essential anatomical knowledge that will be used later. The skull, in superior view, is wider in its posterior part than in its former part [Plate 1/10]. The plane of vision [Plate 3/10 (20).] Passes over the temporal bone (13) just above the supra-mastoid ridges (15). Regarding the plane of the field of vision, temporal bony prominences [Plate 4/10. (e) and (f)] are on average at this level of 16Omm [Boards 1/10 and 2/10]. Finally the vertical planes [Plate 3/10. (21) and (22)] orbital (21), [Plate 4/10 passing through (c), (a), (b), (d)]. and temporal (22), [Plate 4/10. passing through (e) and (f)] are averaged 75mm apart. To finish completely on the anatomy, say that the lower half of a hand (that is to say the fingers and the half of the metacarp) normal of an adult man slips and moves without any difficulty in a space 8Omm high [Plate 4/10. (r)] is what the experiment shows. End of anatomy.

  A little physiology of the eye is now necessary: A word on accommodation at distance and on convergence [Plates 4/10 and 5/10].

  Thanks to the lens that behaves like a deformable lens, the eye adapts to the distance. The lens changes its curvatures to obtain the sharpest image. Regarding reading, the optimal reading distance, the proximal punctum, which varies with age, is noticeable for adults who have good eyesight or are well corrected from 33Omm to 4OOmm.

  It is at 400mm that corrective lenses of presbyopes are adapted by ophthalmologists usually. It is actually the most convenient distance. The consumer therefore instinctively positions his eyes 4OOmm away from the [Plates 4/10 and 5/10. (k)] that it is aimed at. Each eye targets the same point and as they are spaced 62mm the two lines of vision form a cone, it is the convergence mechanism of the eyeballs.

End of / a physiology of / 'cei /.

  We come to the combination of these three poles of knowledge: the anatomy of the skull, the physiology of the eye, that is to say, the functioning of the eye and the eyes of the eye. 'optical. The result is represented by [boards 4/10 and 5/10] and [Board 10/10].

  (j) represents the keyboard, (n) its small side and anterior protectors 20mm high, (k) one of the 10mm / 10mm keys, (m) the screen surface pierced with a hole, that is, say the Anti-Code, (q) the left hand that holds this Anti-Code (Fig 10), (r) the right hand that is placed between the horizontal surface of the Anti-Code and the keyboard (Fig 10) , (s and s' not drawn) the arms and forearms on each side. The eyes are instinctively 400mm from the key that is perfectly visible in binocular vision (Fig 4 and 5). So that the vision is perfect, that is to say with the impression of relief which is necessary to guide the index (Fig 10), it is necessary that the vision is binocular. The left hand (q) instinctively guide the plane of the horizontal surface of the Anti-Code (m) to 80mm from the plane (j) of the key (k). At more than 80mm binocular vision would be embarrassed and less than 80mm is the right hand (r) that would be cramped. The position at 80mm will impose itself by automatic central cerebral correction instantly. At 80mm from the plane (j) of the keys, the hole of the horizontal surface of the Anti-Code (m) is about 20mm in diameter. It is a value that derives from the pattern of light rays, the agreed postulates, and the following.

  The result in binocular vision or play plays: Thus only the one who has the keyboard in hand has this cone of vision on the entire surface of the key (k) it aims. Slowly moving the Anti-Code (m) it sweeps the keyboard from right to left and back and forth and hits the keys that match its code. He can even pretend to hit several times and actually hit only four times. Confirmation does not require the use of the Anti-Code. These [boards 4/10 and 5/10] show that the cheek never plays, the copier (rays (T)}, to see the key (k) chosen by the one who holds the keyboard.

  When is it in monocular vision? To hit easily with precision you have to be in binocular vision but to simply see and copy the monocular vision is enough. The cameras only have monocular vision.

  In play cheek, we return to the previous situation, but by positioning back and laterally to the skull of the one who is typing his code? --- So in tangential view to the anterior skull and with one eye or with a camera? [Boards 1/10. (T)].

  We said in the course of anatomy that: With regard to the plane of the field of vision, the temporal bony prominences (e) and (f} [Plates 1/10. (E) and (f) and 2/10. ( f)] are on average at this level spaced 16Omm apart from each other [Plate 4/10 (e) and (f)] The skull is wider at the ears {16Omm between (e) and (f)} at the level of the eyes (11Omm between (c) and (d)} and this is very useful to solve the problem which concerns us.It is a mandatory offset of 5Omm [Plate 4/10: {160 -62 100 and 100/2 = 50)] compared to each eye in a bald subject and much more if the hair is abundant and remember that it is especially women who have much more hair than men who do the shopping. The tangent (T) from (e) for example [Plates 1/10, 4/10 and 5/10 (T)] is therefore offset by 5Omm with respect to the right eye, so even in monoculars, even if the consumer holding the keyboard is motionless like a statue, the [boards 4/10 and 5/10] show that the light ray (T) passes next to the key (k). It is therefore impossible to see or film what is written on the key (k). But immobility is not peculiar to man, it is a great art to play the same statues. Everything moves, the head of the subject who is typing his code moves, his left hand (q) moves by moving the Anti-Code (m), the right hand (r) is moving, the distance from the eyes (a) and ( b) the keyboard (j) moves, the distance from the Anti-Code (m) to the keyboard (j) moves. No fixed camera directed to the keyboard (j) could capture the keystroke of the code, and even no moving camera, even if it did not have to hide itself, would succeed. It is the relentless laws of optics that attest to it as shown in [Plates 4/10 and 5/10]. At this stage everything is not yet won: Whether in binocular vision

  or in monocular vision, we have just considered cases of tangential vision fraud in the skull of the consumer who has the keyboard in hand. Figure 4 [Plate 4/10] and especially Figure 5 [Plate 5/10] show clearly that if the Anti-Code consists only of a horizontal surface and even if it is 18Omm of side, so larger than the dimensions we have chosen, the keyboard can be easily seen in left peripheral fields (p) or right (o) and previous. The back of the Anti-Code is protected by the trunk of the consumer. Laterally his hands (q, r) and forearms and arms (s) are not enough. It is therefore imperative to find a parade. This is done by placing on the three free sides a vertical surface. The width of the vertical side surfaces are measured on [Plate 5/10]. So for 18Omm / 18Omm we should opt for a width of 37.5mm.

  For a surface of 154mm / 154mm it would take a width of 44mm and for the dimensions of the Anti-Code we have chosen, 154mm / 141mm, we need 47.3mm, we will opt for 5Omm width for ABIJ surfaces, ACNK and BbML [Plates 6/10 and 7/10]. Here again we see how these [Plates 4/10 and 5/10] are useful to find all the values of the Anti-Code whatever the chosen postulates. The flaps (G) for the right-handed and (H) for the left-handed [Plates 6/10 and 10/10] are cut (see description) so that the Anti-Code is not faulted laterally on the side of the flap folded by the hand that holds the Anti-Code. Finally, remember that the small triangles rectangles of 2mm on 5Omm cut at the four corners A, B, C, b and grooves already described allow easy automatic folding of the Anti-Code to give it the dimensions of a ticket of 50 This will allow cash dispensers to use the money slot already in place. It is therefore not necessary, remember, to change the appearance of current ticket machines.

At this stage 'Asti-Code exists.

  Consumers will learn very quickly to use this curious and very useful advertising and just as anti-theft systems of cars have never completely suppressed car thefts, this system will have, human nature being what it is, some flaws that we should not aggravate voluntarily outgoing values recommended to make the system less foolproof.

  The Anti-Code will become a common object as is the credit card. It is to give all its importance to advertising that the title of this invention begins with: Advertising media ...
