The maximum range of RFID (Radio Frequency Identification) cards can vary depending on the specific type of RFID technology used and the frequency at which it operates. RFID systems commonly operate in low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF) bands.
Low-Frequency (LF) RFID:
Frequency Range: 125 kHz to 134 kHz
Maximum Range: Typically up to 10 centimeters (4 inches)
High-Frequency (HF) RFID:
Frequency Range: 13.56 MHz
Maximum Range: Typically up to 1 meter (3 feet)
Ultra-High-Frequency (UHF) RFID:
Frequency Range: 860 MHz to 960 MHz
Maximum Range: Can vary significantly but may reach up to several meters (10 feet to 30+ feet), depending on factors such as antenna design, power levels, and environmental conditions.
It's important to note that these are general ranges, and actual performance can be influenced by factors such as the RFID system design, interference, the presence of obstacles or materials that may attenuate the signal, and the power of the
RFID reader. Some specialized RFID systems, such as active RFID, can have much longer ranges, sometimes exceeding 100 meters.
Keep in mind that different applications and use cases may require different RFID technologies based on factors like range, cost, and data transfer speed.
