Active RFID vs. Passive RFID
Active RFID tags have an embedded transmitter and power source, enabling them to emit signals without requiring external readings. They are more expensive than passive RFID tags but have a wider range. Active tags are typically used for tracking wide-ranging items such as warehouse management.
Passive RFID tags do not have a power source. They rely on the power emitted by the RFID reader to activate and transmit signals. Therefore, passive RFID tags are much cheaper than active RFID tags but often have a reading range of only a few meters. Passive RFID tags are typically used for applications where a short reading range is sufficient, such as retail asset management.
