<h2>Introduction to RFID Technology</h2>
Radio Frequency Identification (RFID) is a wireless technology that uses electromagnetic fields to automatically identify and track rfid netherlands attached to objects. These tags contain electronically stored information, which can be read from several meters away without requiring a direct line of sight. RFID systems consist of three main components: the tag (or transponder), the reader (or interrogator), and the backend system for data processing. The technology is widely used in various industries, including logistics, retail, healthcare, and access control, due to its efficiency and automation capabilities. However, one of the most common challenges faced by RFID implementations is its interaction with metallic surfaces, which can significantly affect performance.


<h2>How RFID Interacts with Metal</h2>
RFID technology operates based on radio waves, which are a form of electromagnetic radiation. When these waves encounter metal, several physical phenomena occur that can interfere with RFID functionality. Metal is highly conductive and reflective to radio frequencies, causing two primary issues: signal reflection and absorption. Signal reflection can lead to multipath interference, where waves bounce off metal surfaces, creating dead zones or reduced read ranges. Absorption, on the other hand, dissipates the energy of the radio waves, weakening the signal and making it difficult for the reader to communicate with the tag. This is particularly problematic for passive RFID tags, which rely on energy harvested from the reader's signal to power up and respond. As a result, standard RFID tags often fail or sensor rfid poorly when placed directly on or near metal objects.

<h3>Types of RFID and Metal Interference</h3>

Not all RFID systems are equally affected what is nfc cover metal. The impact varies based on the frequency band used:


- Low-Frequency (LF) RFID (125-134 kHz): These systems are less susceptible to metal interference because they use near-field communication and magnetic coupling, which can penetrate metallic environments to some extent. However, read ranges are short (typically a few centimeters), and performance may still degrade if metal is too pervasive.
- High-Frequency (HF) RFID (13.56 MHz): HF RFID, commonly used in NFC (Near Field Communication) applications, also relies on magnetic fields The Use of RFID for Human Identity Verification
