Some authors received a message related their final paper submission and registration fee payment. In a relevant number of cases (50% or even more), due to limited number of characters in bank wire transfer description, the name of issuing author is missing in our bank records, so in these cases we are unable to check whether both submission and payment of registration fee have been fullfilled. While we apologize with authors, we point out that have no responsability with this situation and we need a proof of payment for verification. We kindly request to upload copy of receipt in your own area at http://cms.iecon2016.org. Thank you for your understanding.
