How RFID Works

Hi ya! How're things with you today? Recovered from St. Paddy's Day, have you? Don't suppose a virtual coffee and a treat will hurt much, eh? Help yourself. Say...do you hate standing in a line at the supermarket as much as I do? It's not the waiting. It's the person in front of me who has a cart full to the top but is carrying something in one hand so s/he can only unload the cart one item at a time. Gr-r-r-! Well that may be about to end, eh.

Long checkout lines at the grocery store are one of the biggest complaints about the shopping experience. Soon, these lines could disappear when the ubiquitous Universal Product Code (UPC) bar code is replaced by smart labels, also called radio frequency identification (RFID) tags. 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 bank will then be notified and the amount of the bill will be deducted from your account. No lines, no waiting.RFID tags, a technology once limited to tracking cattle, are tracking consumer products worldwide. Many manufacturers use the tags to track the location of each product they make from the time it's made until it's pulled off the shelf and tossed in a shopping cart.

Outside the realm of retail merchandise, RFID tags are tracking vehicles, airline passengers, Alzheimer's patients and pets. Soon, they may even track your preference for chunky or creamy peanut butter. Some critics say RFID technology is becoming too much a part of our lives -- that is, if we're even aware of all the parts of our lives that it affects.

I may do a follow-up on this because RFIDs are becoming more and more commonplace in our society, eh. Big brother is not only watching you but he knows what kind (and colour) underwear you prefer and why!

See ya, eh!
