# 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 I 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.
