EM4100type

The EM4100 is a type of radio-frequency identification (RFID) chip that is widely used in various applications, including access control systems, inventory management, and ticketing systems. Developed by EM Microelectronic, a Swiss-based semiconductor company, the EM4100 chip is a 125 kHz read-only RFID transponder that operates at a low frequency.

The EM4100 chip consists of a coil for transmitting and receiving data, a substrate for mounting the coil and other components, and a layer of ferrite material to improve the chip's sensitivity and reading range. The chip can store up to 32 bits of data, but is typically used to store a single 8-digit hexadecimal code.

The EM4100 chip is relatively small, measuring only 2.5 x 2.1 x 0.55 mm. It is often used in environments where a simple and cost-effective RFID solution is required. The chip's low power consumption and relatively long read range make it suitable for applications such as access control for parking garages, offices, and residential buildings.

The EM4100 chip can be integrated into various form factors, including key fobs, cards, and tags. It is also commonly used in conjunction with EM4100-compatible reader antennas. The chip's widespread adoption has led to the development of various compatible reader devices, ensuring seamless interoperability.

The EM4100 chip's user base has expanded beyond traditional access control and inventory management applications, with uses ranging from laundry and catering services to other industries where identification and tracking of products or personnel are essential.
