Development of a mobility solution based on Movilizer .NET connector and Movilizer client that integrates the data captured using Movilizer client. The main objective was to show the capabilities of Movilizer in order to register all the required data of official documents delivery and reception. One of the keys of the project was to ensure the privacy of all final users data using end-to-end encryption, and generating the corresponding report related with each transaction. Delivery postmans use handhelds to register the data. PoC.
