The law (Art. 78–1 to 78–6 of the French Code of criminal procedure ("Code de procédure pénale") mentions only that during an ID check performed by police, gendarmerie or customs officer, one can prove his identity "by any means", the validity of which is left to the judgment of the law enforcement official. Though not stated explicitly in the law, an ID card, a driving licence, a passport, a visa, a "Carte de Séjour", a voting card are sufficient according to jurisprudence. The decision to accept other documents, with or without the bearer's photograph, like a Social Security card, a travel card or a bank card, is left to the discretion of the law enforcement officer.
