Overview
The Inventory Master Contactless IC HF RFID Reader Writer Module is a series of RFID read or write module. It has various functions and supports multi-ISO or IEC standard of contactless card. The RF protocol is complex, but the designer 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. The impedance between RF module and antenna was tuned by impedance analyzer. And then the module has excellent performance and stability.
Features
- Ferrite plate under the antenna, good performance for metal-around environments
- EMV 2010 certification ability in RF protocol part
- 2 SAM slots, full fill payment system usage
- USB HID interface, convenience to use on PC
