The authenticity of Deutz original parts is now validated by two methods. A hologram, which can be tested under an ultra violet banknote tester, has been added to each part. This is in addition to the previous logo, which turns red under the same light. The hologram is automatically destroyed when removed from the part to prevent its transfer to another part. A range of adhesives has been used to allow the hologram to be used on a range of surfaces.
