Chapter 1 Overview
This series of readers have built-in small gain PCB antenna, excellent structural
design, can effectively prevent the tag from being misread or serial read, positioned in
the use of close reading card scenarios. Suitable for supply chain management, asset
management and other fields of card issuing applications and close card reading
applications. At the same time, it can support the optional high-gain ceramic antenna,
combined with the high-performance RFID module to meet the use of higher card
reading performance scenarios.
The series currently has three main products
