RS232 Serial Port 13.56MHz IC Card Reader for Access Control System

Product Overview

The RS232 Serial Port IC Card Reader is a contactless smart card reading device designed for reliable RS232 serial communication. Operating at 13.56MHz, it supports MIFARE® IC cards such as S50 and S70, with a reading distance of up to 10cm and a fast response time. Featuring a standard DB9 interface, the reader obtains both power and data communication through the serial port, eliminating the need for an external power supply. It is widely used in access control, attendance management, membership systems, parking management, and industrial automation applications.

FAQ

Q1: Does the reader require driver installation?

A: No. The reader uses standard RS232 serial communication and can be accessed directly through serial terminal software without additional drivers.

Q2: Does it support 125kHz ID cards?

A: No. This model supports only 13.56MHz IC cards. For both IC and ID card reading, please choose a dual-frequency IC/ID card reader.

Q3: Can the output data format be customized?

A: Yes. Customized output formats such as card UID only, prefixes, suffixes, or specific data structures are available for bulk orders.

Q4: Why is the reading distance shorter than expected?

A: The standard reading distance is up to 10cm. Please ensure that a compatible IC card is being used and that there is no metal interference near the reader.

Q5: Can it be used with Linux or Android systems?

A: Yes. Any system supporting RS232 serial communication can use the reader. Android devices may require a USB-to-RS232 adapter and compatible serial communication software.
