Product Overview
The SDEE-RF-FM is a non-contact IC card reader/writer module developed in-house. The mainboard operates at 5V and features an RS232 serial communication interface. It supports both the first-power protocol and industry-standard protocols, enabling read/write operations for Type A and Mifare One (MF1) cards compliant with ISO14443.
Customizable communication protocol; defaults to a custom first-power protocol.
Supports reading and writing of Type A and MIFARE One (MF1) cards compliant with ISO14443 standards.
Compact, lightweight, and easy to install.
