On Monday, the finalists for a contest called Rethink Supply Chains were announced. The two ideas were a mobile phone system that would be used to collect data on forced labor, and a survey tool on cellphones would assess working conditions for fishermen in Ghana. The winner of the competition will be announced in April and will win a $250,000 prize. It is estimated that as many as 18.7 million people worldwide are victims of forced labor.
