  The Information Bureau shall furthermore be charged with collecting all personal valuables,
  including sums in currencies other than that of the Detaining Power and documents of
  importance to the next of kin, left by prisoners of war who have been repatriated or released, or
  who have escaped or died, and shall forward the said valuables to the Powers concerned. Such
  articles shall be sent by the Bureau in sealed packets which shall be accompanied by statements
  giving clear and full particulars of the identity of the person to whom the articles belonged, and
  by a complete list of the contents of the parcel. Other personal effects of such prisoners of war
  shall be transmitted under arrangements agreed upon between the Parties to the conflict
  concerned.
  ARTICLE 123
  A Central Prisoners of War Information Agency shall be created in a neutral country. The
  International Committee of the Red Cross shall, if it deems necessary, propose to the Powers
  concerned the organization of such an Agency.
  The function of the Agency shall be to collect all the information it may obtain through official or
  private channels respecting prisoners of war, and to transmit it as rapidly as possible to the
  country of origin of the prisoners of war or to the Power on which they depend. It shall receive
  from the Parties to the conflict all facilities for effecting such transmissions.
  The High Contracting Parties, and in particular those whose nationals benefit by the services of
  the Central Agency, are requested to give the said Agency the financial aid it may require.
  The foregoing provisions shall in no way be interpreted as restricting the humanitarian activities
  of the International Committee of the Red Cross, or of the relief Societies provided for in Article
  125.
  ARTICLE 124
  The national Information Bureau and the Central Information Agency shall enjoy free postage
  for mail, likewise all the exemptions provided for in Article 74, and further, so far as possible,
  exemption from telegraphic charges or, at least, greatly reduced rates.
  ARTICLE 125
  Subject to the measures which the Detaining Powers may consider essential to ensure their
  security or to meet any other reasonable need, the representatives of religious organizations,
  relief societies, or any other organization assisting prisoners of war, shall receive from the said
  Powers, for themselves and their duly accredited agents, all necessary facilities for visiting the
  prisoners, distributing relief supplies and material, from any source, intended for religious,
  educational or recreative purposes, and for assisting them in organizing their leisure time within
  the camps. Such societies or organizations may be constituted in the territory of the Detaining
  Power or in any other country, or they may have an international character.
  The Detaining Power may limit the number of societies and organizations whose delegates are
  allowed to carry out their activities in its territory and under its supervision, on condition,
  however, that such limitation shall not hinder the effective operation of adequate relief to all
  prisoners of war.
