While protecting tax revenues, two basic strategies can be applied. Governments can build „big brother systems,“ implement extensive surveillance, face protests, and legal actions. The other way insists in issuing documents that simply cannot be counterfeited – banknotes, highway vignettes, stamps, tax stamps, coupons, etc. In real life, measures from both sides need to be used. However, the more resistant are documents, the less obtrusive can be surveillance systems, and the lower are total costs. Moreover, creating full trust into state documents is similarly important as properly working justice system. Unlimited resources can be spent on technology and complicated production. It is important to find the right solution to cover risks for an acceptable budget. We help our clients to answer questions, such as the following: - What processes and issues should be covered by security documents /labels /stamps. - How likely counterfeit attempts can be expected. What technologies can be used by the falsifiers? - What combination of security elements should be used to protect state documents? - Definition of processes for security elements distribution, application, and check. - What are criteria for technology providers selection?
