Definitions
- the present invention relates to a system for marking cash or other valuables.
- marking being designed so as to provide a permanent visible reaction upon contact with substances deployed by a security marking system in order to degrade or neutralise the value of the cash or valuables being marked.
- a security marking system can also produce human readable markings which will provide information that can identify the security equipment that deployed the marking system.
- Such security systems also often deploy taggents which are unique to the individual security container or other deploying system.
- taggants may comprise a unique combination of rare metals, or artificial DNA, to create a large number of 'codes'.
- Each item of security equipment is allocated such a unique 'code', which is included in the security ink.
- the resistance of such stains and taggants to removal by criminals is an ongoing problem for the developers of such systems.
- One problem is that there are a number of different substrates, inks and coatings used in the manufacture of banknotes in different countries, and even between denominations and series of banknotes within a single country.
- the combination of different substrates, inks and coatings is constantly changing as banknote issuers try and make counterfeiting more difficult.
- banknote issuers are moving towards declaring such stained banknotes as either illegal tender or mutilated banknotes such that they are not accepted for normal transactions.
- a disadvantage with this move is that high speed banknote counters are often unable to detect the security stain on the banknotes, resulting in stained notes being dispensed from automatic teller machines and the like.
- the banks have an obvious problem in issuing via their automatic teller machines banknotes which they are declaring as illegal tender or mutilated.
- issuers of banknotes are also, inadvertently, working against those deploying such security systems.
- issuers try to extend the average life of a banknote by providing stain resistant coatings.
- future issues of the Euro for example are likely to be manufactured on a polymer (plastic) substrate so making staining more difficult.
- an item characterised by having at least one security marker formed as part of the item, where the at least one security marker is responsive to an external stimulus to undergo a permanent change.
- the change to the feature is visible to the naked eye so that members of the public, bank staff and the like are able to easily recognise that the banknote is no longer valid.
- the change also generates a 'code', unique to the deploying security system, and which is also visible to the naked eye so that there are no costs involved in extracting the code.
- polymers can be produced which change their visible optical properties in response to an external stimulus.
- Such polymers can be used to create a sensing device which can change colour, indicating exposure to the specified stimulus.
- the stimulus sensed could be temperature, light (visible, infrared or ultra violet), electric field, pressure, ion concentration or biochemical reaction.
- the invention provides a sensor polymer which is affixed to a banknote during manufacture.
- banknote degrading security systems are deployed which contain within the staining ink the substance to which the sensor polymer is designed to sense. Upon the sensor polymer coming in contact with the said substance the polymer changes its colour, for example.
- the polymer may change from opaque to transparent (or visa versa) such that a printed image under the sensor polymer can appear or disappear.
- Such an area that is made visible by a change of opacity may be designed as to reveal a word such as 'VOID'.
- such an area covered by such a sensor polymer may obscure one or more security features of the banknote so that high speed note counters will reject the banknote, so preventing the banknote from returning into global circulation.
- a plurality of sensor polymers may be affixed to a banknote during manufacture. Such polymers maybe affixed into an array or be affixed sequentially along the face of the banknote. Preferably each sensor polymer is designed to react with a different substance.
- Banknote degrading security systems can be deployed which contain within the staining ink a combination of substances to which the sensor polymers are designed to react. A unique code can therefore be created by mixing various combinations of such substances in the staining ink.
- the polymer array Upon the sensor polymer array coming into contact with the ink containing a mixture of substances the polymer array changes its appearance. Those sensor polymers which react with the combination of substances contained within the security ink change colour, whilst any other sensor polymers would remain unchanged. The changed polymer array would therefore generate a unique pattern which is visible and readable by the human eye.
- each degradation security system has a unique or rare combination of substances designed to react with the individual elements of such a sensor array.
- the array of sensor polymers is deployed in addition to a single larger sensor polymer, which reacts to a substance common to all staining inks.
- one or more sensor polymers are affixed to banknotes during manufacture, each of which is capable of effecting a number of different colour changes according to the combination of substances detected. In this way a smaller number of sensors maybe deployed.
- the invention in all of its embodiments, benefits from a solution which involves features incorporated into the manufacture of a banknote which are designed to interact with features built into systems intended to protect such banknotes. This maximises the effectiveness of the staining system and in particular the resilience to removal of such stain.
- a security system for transporting an item, whereby in the event of a theft or an attempted theft a spoiling agent release mechanism releases a spoiling agent such that it contacts the security marker to cause it to undergo a permanent change.
- the banknote 1 illustrated in Figure 1 has a security feature 2 imprinted upon its face.
- security feature may be, for instance, an infrared emitter which can be detected by high speed banknote counters.
- a transparent sensor polymer 3 which is laid over the security feature 2 such that the security feature can still be detected.
- the banknote 1 also contains an array 4 of individual sensor polymers 5, 6 etc. through to 15. Each of the individual sensor polymers 5, 6 etc. through to 15, and the larger area sensor polymer 3 is responsive to a different substance.
- the same banknote 1 is illustrated in Figure 2 after being subjected to staining ink containing a mixture of substances to which sensor polymers 3, 5, 7, 8, 11 and 14 are responsive.
- Each of these polymers 3, 5, 7, 8, 11 and 14 have changed colour in response to the staining ink as indicated by shading on Figure 2 .
- the changed opacity of sensor polymer 3 has obscured security feature 2 which will no longer be detected by a high speed counting machine. Such a note being processed by such a machine would therefore be diverted to the banknote reject pile and removed from circulation.
- Sensor polymers numbers 5, 7, 8, 11 and 14 in Figure 2 have also changed colour in response to the staining ink as indicated by shading on the figure.
- the sensor polymer can be selected from suitable candidate polymers.
- suitable polymers include hydrogels.
- a stimuli responsive hydrogel is a long chain polymer that expands or contract when it comes into contact with specific stimuli. It is known that the changes can be made reversible and repeatable if some cross linking is provided within the polymer. To make the change non-reversible the cross linking is broken. This may be achieved by a component within the stimulant or by the swelling of the hydrogel exceeding the parameters of the cross linked polymer. It is also know that the polymers can be made responsive to specific bio-molecules - see for example Hoffman, "Bioconjugates of Intelligent Polymers and Recognition Proteins for use in Diagnostics and Affinity Separation", Clinical Chemistry, 1478 - 1486, 2000 . Similarly components in a stimulant can cause the formation of permanent cross links, and such permanent cross linking to give rise to irreversible charges.
