RFID TAGS
RFID tags can come in numerous physical forms with different capabilities, including:
- Key fobs (active read/write).
- Wristbands
- Bulk metal tags (use-once passive read-only).
- Garment disks (reusable active read-only).
- Animal Identification
- Smart Card credit-cards with RFID tags embedded for storing personal information.
There are three types of RFID tag – Active, Semi-passive and Passive.
PASSIVE RFID
Passive RFID tags rely entirely on the reader as their power source. These tags are read up to 20 feet (six meters) away, and they have lower production costs, meaning that they can be applied to less expensive merchandise. These tags are designed to be disposable, along with the disposable consumer goods, such as CD and DVD logos, on which they are placed.

ACTIVE AND SEMI PASSIVE RFID
Active and semi-passive RFID tags use internal batteries for power. An active RFID tag uses its battery to send radio waves to a reader, whereas a semi-passive tag relies on the reader to supply its power for sending information. Because these tags contain more hardware than passive RFID tags, they are more expensive. Active and semi-passive tags are reserved for costly items that are read over greater distances – they broadcast high frequencies from 850 to 950 MHz that can be read up to 100 feet (30 meters) or more away.
