# Council Directive 1999/37/EC of 29 April 1999 on the registration documents for vehicles, Division C: Physical security features of the smart card

Extent: E+W+S+N.I.

The threats to the physical security of documents are:
Production of false cards: creating a new object which bears great resemblance to the document, either by making it from scratch or by copying an original document.
Material alteration: changing a property of an original document, e.g. modifying some of the data printed on the document.
The material used for Part II of the registration certificate shall be made secure against forgery by using at least three of the following techniques:
microprinting,
guilloche printing*,
iridescent printing,
laser engraving,
ultraviolet fluorescent ink,
inks with viewing angle — dependent colour*,
inks with temperature — dependent colour*,
custom holograms*,
variable laser images,
optical variable images.
Member States are free to introduce additional security features.
As a basis, the techniques indicated with an asterisk are to be preferred as they enable the law enforcement officers to check the validity of the card without any special means.
