Wal-Mart last week kicked its on-again, off-again RFID tagging program into higher gear. Starting next week, it will track socks, jeans, shirts and (ahem) underwear with RFID tag technology based on EPCglobal’s “Gen 2” UHF standard. With predictability you could set your watch to, the consumer-privacy alarm bells clanged across the land.
Up popped one of the most-quoted critics of the plan, Katherine Albrecht, a talk-show host and author of a book that argues RFID technology is the fulfillment of a Biblical “end of time” prophecy.
Despite the clamor, though, the sun rose the next day. And its light shone on the challenges and promise of RFID technology in the months and years ahead. RFID investment, like much of the rest of the economy, was packed into the deep freeze the past two years. VDC Research Group reported recently that growth in core RFID hardware overall, fell from nearly 20 percent year on year to 5 percent in 2009.
But now comes the thaw. As the economy recovers, companies are keen to wring as much productivity gains as they can before they ramp up hiring again. RFID technology is key lever for that increased productivity. Earlier this year, ABI Research reported that that global RFID market would grow 15 percent to $5.35 billion this year.
Predictions are predictions and nothing more, but consider how much more promising the RFID market has become in recent years. A 2006 report by BCC Research predicted an RFID market of $1 billion in 2011. We’re on target to do 5X that now. Usually, forecasters are overly optimistic in their predictions; in the case of RFID they have been proven overly cautious.
If you’re looking for a market to drive your RF components and antenna technology into, life is good. Just ask the engineers at Avery Dennison, where the stock price has doubled since March of 2009.
If you’re worrying about privacy concerns, get a grip. Have a cellphone? They know whom you’re talking to. Walking on a London street? They see you at every corner (yes, your hair’s a mess). Have a FasTrak-type device to speed through bridge toll booths, they know where you’re been.
That horse left the barn years ago. Yet if technology has its pernicious potential, it also can be used to counter-act them: There’s no reason RFID tags can’t be built to solve the retailer’s inventory problem AND be automatically de-activated the minute you leave the store.
Failing that, there’s the mechanical solution: Have the clerk just yank it off after you buy your items.
To Mark's point, I think the good news is Wal-Mart is probably smart enough to watch its analytics and if no one's buying BVDs anymore (remember those?), they'll get religion.
But, stepping up a level, this is really an interesting time--the new confluence of the famous three Cs, only the Cs are a little different: Computing, Communication and Cognition.
The opportunity resides in that interface between the trillions of sensors begin deployed and the "cloud" if you will, where all that sensed data gets computed and acted on. Some scary consequences and possibly unintended ones too, but lots of positives too.
The technology is indeed a productivity booster, and there are easy solutions to privacy issues as Brian said at the end of the article. No reason for alarm I would say.
As for underwear, I am resisting the temptation of commenting...too many puns :-)
My fear is that all those people buying the RFID-tagged underwear will stop wearing underwear entirely when visiting Wal-Mart retail stores because they will fear being watched. I for one will steer clear of all Wal-Mart stores when that happens!
JD, excellent point and fabulous pun.
How about added functionality: sit too long and it jolts you into activity.
Or an integrated device that's woven into fabric that functions as RFID device until you leave the store and then energy-harvesting device that self-warms during the winter.
The possibilities are, um, endless.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
