Direct EXchange (DEX) is a digital communication protocol that extends the Uniform Communication Standard (UCS), it enables direct store delivery drivers to transmit digital invoices to the retailer's receiving clerk at the loading dock.
Created by the Uniform Code Council (UCC), DEX has been adopted by most national grocery chains. This standardized system reduces time, costs and inaccuracies inherent in paper invoices. Originally designed in the early 1980's, the DEX protocols have been revised several times over the years. The most current version is 5030 version, released in 2006 .
SmartDEX solution is a hardware and software bundle combining Android handheld computers from Zebra and embedded DEX software from Versatile Mobile Systems.
SmartDEX on Android is currently available only as an embedded client. This means that SmartDEX must be called from a parent route or delivery application. That application must supply the necessary invoice data to SmartDEX in order to run a DEX session.
