What is RFID?
Radio-frequency identification (RFID) is an auto-identification technology, similar in concept to other common auto-identification technologies such as bar code scanners, magnetic strip readers, or magnetic ink readers.
It stands for Radio Frequency Identification. It helps to automate
applications, gather data and information of the tagged item/object which
may include
Description( EPC)
Time
Location
Physical parameters (temperature, pressure, humidity, etc)
Radio frequency identification (RFID) technology uses radio waves to
automatically identify physical objects (either living beings or inanimate
items).
Advantages of RFID vs. Barcode
No requirement for line-of-sight
Dynamic information carrier (read/write)
High memory capacity if needed
Anti-collision (many tags can be read at the same time)
Robust and reliable
Performs in rugged, harsh environment
Cheaper in long term
No human intervention
Reader virtually maintenance free
