Passive vs. Active RFID Comparison
RFID vs. Barcodes | Passive vs. Active RFID | RFID for Tracking Assets
The primary difference betwee passive and active RFID tags is that active tags
are powered by a battery and automatically broadcast their signal, whereas
passive tags do not have a power source and only transmit a signal upon receiving
RF energy emmited from a reader in proximity of the tag.

$15-50 depending upon quantity, options (motion sensor, tamper detection, temperature sensor), and form-factor |
| Ideal Use |
For inventorying assets using handheld RFID readers (daily, weekly, monthly quarterly, annually). Can also
be used with fixed RFID readers to track the movement of assets as long as security is not a requirement.
|
For use with fixed RFID readers to perform real-time asset monitoring at choke-points or within zones. Typically
necessary when security is a requirement.
