RFID who?

POSTED BY on Jun 22 under Uncategorized

The term RFID is being thrown around a lot these days and I thought I shall make this concept a bit easier to understand for the non-techies visiting this blog.

RFID – Radio Frequency Identification

Long checkout lines at the grocery store used to be one of the biggest complaints about the shopping experience. We are now seeing these lines slowly disappear with the smart labels, also called radio frequency identification (RFID) tags replacing the ubiquitous Universal Product Code (UPC) bar codes. RFID tags are intelligent bar codes that can talk to a networked system to track every product that you put in your shopping cart.

Imagine going to the grocery store, filling up your cart and walking right out the door. No longer will you have to wait as someone rings up each item in your cart one at a time. Instead, these RFID tags will communicate with an electronic reader that will detect every item in the cart and ring each up almost instantly. The reader will be connected to a large network that will send information on your products to the retailer and product manufacturers. Your credit card company will then be notified of the total amount and this amount will be deducted from your account. No lines, no waiting. We are talking 2020 here, which is not too far away.

Passive RFID Tag


There are two kinds of RFID tags, (a) Passive (b) Active

Passive tags are tags that almost always relies on the power generated by the RFID reader to communicate. You can see the application of this technology on expensive clothing and large items when not removed beeps while you walk out of the store pass through the reader.

Active tags are tags that has a battery inbuilt and does not rely on the power generated by the reader. So these tags can be read even from 100 feet away in some cases.
