Identity document
Other forms of officially accepted identification include the driver's license and the birth certificate. However, these are accepted only in limited circumstances and cannot take the place of the ID Card in most cases. The ID Card is mandatory for dealing with government institutions, banks or currency exchange shops. A valid passport may also be accepted, but usually only for foreigners.
Certificate of incorporation
A certificate of incorporation is a legal document relating to the formation of a company or corporation. It is a license to form a corporation issued by state government or, in some jurisdictions, by non-governmental entity. Its precise meaning depends upon the legal system in which it is used.
