The Post It project won the challenge released by CTT at the Taikai platform to present any item’s tracking information solution for smartphones.

This information is collected through a photo of the fluorescent barcode, the” ID tag”, printed by the Production and Logistics Centers’ sorting machines.

With more than 80 competitors from all over the world, the winning team is from Brazil, and offered an app that can read all the information regarding the ID tag in less than 3 seconds and with different light conditions, using only a smartphone and with no need for internet connections or any other external processing.
