... The provisions of the present Convention constitute no obstacle to the humanitarian activities which the International Committee of the Red Cross or any other impartial humanitarian organization may, subject to the consent of the Parties to the conflict concerned, undertake for the protection of prisoners of war and for their relief. ...

... The Detaining Power shall assemble prisoners of war in camps or camp compounds according to their nationality, language and customs, provided that such prisoners shall not be separated from prisoners of war belonging to the armed forces with which they were serving at the time of their capture, except with their consent. ...

... Upon the outbreak of hostilities, and pending an arrangement on this matter with the Protecting Power, the Detaining Power may determine the maximum amount of money in cash or in any similar form, that prisoners may have in their possession. Any amount in excess, which was properly in their possession and which has been taken or withheld from them, shall be placed to their account, together with any monies deposited by them, and shall not be converted into any other currency without their consent. ...

... In any event, and subject to the consent of the Power on which they depend, prisoners may have payments made in their own country, as follows: the Detaining Power shall send to the aforesaid Power through the Protecting Power a notification giving all the necessary particulars concerning the prisoners of war, the beneficiaries of the payments, and the amount of the sums to be paid, expressed in the Detaining Power's currency. The said notification shall be signed by the prisoners and countersigned by the camp commander. The Detaining Power shall debit the prisoners' account by a corresponding amount; the sums thus debited shall be placed by it to the credit of the Power on which the prisoners depend. ...

... Prisoners of war detained in connection with a judicial prosecution or conviction and who are designated for repatriation or accommodation in a neutral country, may benefit by such measures before the end of the proceedings or the completion of the punishment, if the Detaining Power consents. ...
