Detailed explanation-1: -Tasked with weathering harsh environmental conditions such as extreme temperatures and moisture, most active RFID tags are encased in a rugged shell. Because of the size of the enclosed battery, circuitry, and bulk of a durable exterior, active RFID tags are usually much larger than passive tags.
Detailed explanation-2: -The main difference in active and passive RFID tags is that active tags use a battery power source to broadcast their signal automatically, and a passive RFID tag does not have any power source. Passive tags only transmit RFID signals when receiving a radio frequency energy from an RFID reader that is within range.
Detailed explanation-3: -A passive RFID tag is a batteryless tag typically used in smaller-scale operations and tracking systems. Because a passive tag has no internal power source, it is instead powered by the energy transmitted from an RFID scanner.
Detailed explanation-4: -Active RFID tags have a transmitter and their own power source (typically a battery). The power source is used to run the microchip’s circuitry and to broadcast a signal to a reader (the way a cell phone transmits signals to a base station). Passive tags have no battery.
Detailed explanation-5: -RFID tags typically do not have a battery (unless specified as Active or BAP tags); instead, they receive energy from the radio waves generated by the reader. When the tag receives the transmission from the reader/antenna, the energy runs through the internal antenna to the tag’s chip.
