Active Tag vs Passive Tag

Active

(With Embedded Battery)

Battery powered Memory, Radio & Circuitry
High Read Range (Up to 200M)
$$$

Passive (Without Embedded Battery)
Reader activates Tag
Shorter Read Range (Up to 3M)
$

How does Passive Tag Work?
Passive Tags
•Tag enters RF Field
•RF Signal powers Tag
•Tag transmits ID (plus Data)
•Reader captures Data
•Reader sends Data to System
•System determines Following Actions
•(Reader may transmit Data to Tag)
