Tags (or chips) consist of two parts:

1) Antennae 2) Processor/ storage

Receives signal from reader and gives a return signal with ID numberReader sends number to database or server

WORKING OF RFID

ACTIVE: Tag signal availability of 100ft.HIGH signal strength VERY LOW required signal strength from the reader

example : Railway cars on a trackSEMI- PASSIVE:

Tag signal availability only within field of readerLOW signal strengthLOW required signal strength from the reader

PASSIVE:Tag signal availability < 10 ft.VERY LOW signal strengthVERY HIGH signal strength required from reader

example : Retail Checkout ( Widely used because very cheap to make)

TYPES
