3. Active Vs. Passive Tags
Active Tags contain an internal battery that allows the reader to increase its read range. This allows them to be more effective in applications that contain humans or animals, vehicles and assets. Active tags are always transmitting. The battery life for an active tag is limited to the transmission of the tag. They are in turn larger and more expensive to build than passive tags.
Passive Tags do not contain an internal battery. When the Passive tag comes in contact with the reader the magnetic field it creates gives energy to the tag which in turn allows the reader to read the tag. The lack of an internal battery allows the tag to be very small. The distance the reader is able to read all depends on the frequency and size of the tag and antenna.
