Overview
The Inventory Master HF RFID Reader Module with Antenna is integrated designing. The impedance between RF module and antenna was tuned by impedance analyzer. And then the module has excellent performance and stability. It has various functions and supports multi-ISO or IEC standard of contactless card. The RF protocol is complex. The design combined some frequently used command of RF card and then user could operate the cards with full function by sending simple command to the module.
