On the technical level there are different possibilities to fight counterfeiting and to prohibit the use of counterfeited parts in machinery and equipment. The aim should be to enable the machinery and equipment to recognize the exchange of wearing or the assembly of additional parts automatically and to check their originality independently. RFID offers not only the conditions to realize the suggested functions but also the possibility to check the authenti-city of products along the whole supply chain. Of course, the checking of parts along the supply chain avoids that co-pies or counterfeited goods break into the original value added chain.
