b. RFID Block Schematic:

A simplified block schematic of an RFID tag (also called transponder) is shown in the diagram below. Various components of the tag are as shown. Normally, the antenna is external to the tag chip, and large in size.

The operation of the RFID tag is described below:

Handshaking with the Reader (interrogator):

The reader continuously emits RF carrier signals, and keeps observing the received RF signals for data.

The presence of a tag (for our discussion, we consider only passive tag) modulates the rf field, and the same is detected by the reader.

The passive tag absorbs a small portion of the energy...

What is the difference between passive and active RFID ...

Answer by Tigerwhit

Confidence votes 41.7K

Active systems have a much longer range than passive systems due to having an internal battery. Because of this an active tag will be much larger and more expensive than a passive tag. The passive tag will basically convert the RF signal from the Interrogator or reader and turn it into energy to return the signal.

Active tags will often be found on larger sized shipping containers/products whereas a passive tag, due to its small form factor can be used on any variety of products, containers, boxes...etc.

Passive tags are usually more durable than...

Active RFID and Passive RFID are fundamentally different technologies that are often evaluated together. While both use radio frequency energy to communicate between a tag and a reader, the method of powering the tags is different.
