Types of RFID TagPassive, Active, metal mountable, specialty tags, etc.

RFID tags contain antenna to enable them to receive and respond to radio-frequency queries from an RFID transceiver

Page 2: Types of RFID Tag

Types of RFID Tag (cont.)

Active - with battery for transmit/receive

Semi-active - use battery only when triggered

Passive - no battery, relying on the collection of RF power from reader for tag operation
