UDI Implementation Guide

This document explains the structure of a UDI, including the mandatory Device Identifier (DI) and variable Production Identifier (PI), and outlines how UDIs must be displayed using AIDC technologies such as barcodes, 2D codes, or RFID. It also addresses common implementation challenges like limited space, low-quality codes, and high-speed production, while promoting KEYENCE code readers as solutions for smooth UDI compliance.
