Passive : RFID tags have no internal power supply.

Do not require power Draws from Interrogator Field Lower storage capacities (few bits to 1 KB) Shorter read ranges (4 inches to 15 feet) Usually Write-Once-Read-Many/Read-Only tags Cost around 25 cents to few dollars

Semi-passive : RFID tags have a small battery.

Active : RFID tags have their own internal power source.

Battery powered Higher storage capacities (512 KB) Longer read range (300 feet) Typically can be re-written by RF Interrogators Cost around 50 to 250 dollars

Line of sight

Right-side-up (mustphysically align carton)

Can tear Limited amount of

data

No encryption

Can read through objects

Tag orientation less of a

problem

Can store megabytes of

data, if needed

Can be encrypted
