Based on the given picture, choose the correct explanation on RFID steps of working concept.

• 1. Tags sends its data to reader.
     Reader Emits radio waves that activate the tag's microchip.
     
     Middleware/Software receives data from the reader, processes it for relevant actions.

• 1. Reader Emits radio waves that activate the tag's microchip.
     Tags then sends its data to reader.
     Middleware/Software receives data from the reader, processes it for relevant actions.

RFID used in

• Access Control

• sensor and control

• Product Tracking and Inventory Control

• Contactless Payment Systems

Component of RFID System is..

• Transponder

• Reader

• Transceiver

• Software

RFID tag is

• a microchip attached to an antenna that is applied to an object

• store the information that describes the object being tracked in the memory of tags

• convert radio waves from RFID tags into a form that can be passed to middleware software

• Tags can be active or passive and read-only, write-once, or read-write

RFID Tag/Transponder device can be

• 
• 
• 
• 

Active tag

• has it own battery

• can be read up to 100ft distance

• can only be read when place near reader

• has it own power circuit

Passive tag is

• without the use of battery

• can be read up to 100ft distance

• can only be read when place near reader

• has it own power circuit

RFID Reader/interrogator

• software that interfaces directly with RFID devices

• uses antennas to communicate with the RFID chip

• convert radio waves from RFID tags into a form that can be passed to middleware software

• filters and formats read data
