RFID vs Barcodes | Difference between RFID and Barcodes
Tweet
As far back as 1960s, the barcodes were used in industrial work environments. In the early 1970s, common barcodes started appearing on grocery shelves. To automate the process of identifying grocery items, UPC barcodes were placed on products and were used to mechanize the process of checking out in store. They are in use today also for allotment, supply chain, retail stores, apparel shops,...

How RFID Works - Technovelgy
How does RFID work? A Radio-Frequency IDentification system has three parts:
A scanning antenna
A transceiver with a decoder to interpret the data
A transponder - the RFID tag - that has been programmed with information.
The scanning antenna puts out radio-frequency signals in a relatively short range. The RF radiation does two things:
It provides a means of communicating with the transponder (the RFID tag) AND
It provides the RFID tag with the energy to communicate (in the case of passive RFID tags ).
This is an absolutely key part of the technology; RFID tags do not need to contain batteries, and can therefore remain usable for very long periods of time...

What is RFID?
RFID tags and Inlays consist of three components: a chip, an antenna and a substrate. RFID tags are manufactured in different shapes and sizes depending on the type of application in which they are used.
RFID operates tags can either be Passive (no internal power source), Semi-Passive (passive but includes a battery) and Active which only operate with a battery.
Active Tags: These tags have a longer read range and larger memories than passive tags and usually operate at 455 MHz, 2.45 GHz, or 5.8 GHz frequencies. Typical read range is from 20 to 100m.
