RFID (Radio Frequency Identification) technology has revolutionized the way we track and identify objects. One of the most widely used RFID frequencies is 125kHz, due to its widespread compatibility and low implementation cost. In this blog post, we will explore the features and applications of a relevant 125kHz RFID reader module.

Understanding RFID

Before we delve into the specifics of the 125kHz RFID reader module, let's briefly understand how RFID technology works. RFID uses electromagnetic fields to automatically identify and track tags attached to objects. The RFID system consists of two main components: the reader and the tags.

The reader emits radio waves, which are then captured by the tags. These tags can either be active (powered by a battery) or passive (powered by the radio waves emitted by the reader). When the reader sends a unique identifier, the tags respond with their stored data, allowing for quick and convenient identification of objects.
