A church in Sweden says it will use the remote controlled devices to distribute small electronic Bibles.
"The bibles are the size of pill boxes and have a display. They require no electricity, but work on their own," said Livets Ord Church mission director Christian Åkerhielm in an interview with SVT.
He added: "Our ambition is to pass on the hope and love of the Christian gospel to a population living in closed areas where they are being denied human rights."
Many of Iraq's Christians have now fled the country after Islamic State terrorists took over large parts of land.
The militants ordered believers to leave, pay a tax or be killed.
Livets Ord Church said in a statement: "The contacts, congregations and organisations we work with testifies unanimously on a huge spiritual awakening in the Middle East, where millions of people turn to the Christian faith and the need and demand for Bibles is gigantic.
"It is this need, we want to help meet this demand through the effort.
"To disseminate Bibles and therefore knowledge of the Christian faith, is something the Christian church has done since the invention of printing - in recent years also closed or inaccessible areas of the Soviet Union, China and North Korea.
"This is not something new, with the exception of the practical approach. The project is done in consultation and collaboration with local partners in the area, with great knowledge of the conditions and terms.
"It occurs in parallel with humanitarian efforts, medical team in refugee camps and distributing food and clothing to the needy."
The operation is expected to start in a few weeks but the exact logistics have not been revealed because of security fears.
