Article 42

The personnel designated in Articles 36 and 37 shall wear, affixed to the left arm, a water-resistant armlet bearing the distinctive emblem, issued and stamped by the military authority.

Such personnel, in addition te[lees: to] wearing the identity disc mentioned in Article 19, shall also carry a special identity card bearing the distinctive emblem. This card shall be water-resistant and of such size that it can be carried in the pocket. It shall be worded in the national language, shall mention at least the surname and first names, the date of birth, the rank and the service number of the bearer, and shall state in what capacity he is entitled to the protection of the present Convention. The card shall bear the photograph of the owner and also either his signature or his fingerprints or both. It shall be embossed with the stamp of the military authority.

The identity card shall be uniform throughout the same armed forces and, as far as possible, of a similar type in the armed forces of the High Contracting Parties. The Parties to the conflict may be guided by the model which is annexed, by way of example, to the present Convention. They shall inform each other, at the outbreak of hostilities, of the model they are using. Identity cards should be made out, if possible, at least in duplicate, one copy being kept by the home country.

In no circumstances may the said personnel be deprived of their insignia or identity cards nor of the right to wear the armlet. In case of loss they shall be entitled to receive duplicates of the cards and to have the insignia replaced.
