One of the common complaints about RFID, from companies considering its use on their products, is that item-level RFID tags
significantly bump up the cost of tracking product. With the
conventional barcode, one code typically sufficed for all items of a
specific product. With item-level RFID, every single item has to be
treated distinctly from its siblings on a store shelf, or what have you.
So
if you have 1000 items to send out to a distributor, your cost of
manufacturing and shipping goes up by 1000 times the cost of an item
level tag, not to mention the cost of pallet- and case-level RFID tags.
As well, each item's RFID tag has to be programmed with a unique code
in the manufacturer's database. In this case, that's 1000 RFID codes
instead of one barcode.
Imagine if you manufactured millions of
items per year. This forces an overhaul in a manufacturer's product
database and in system software (data collection, querying, reporting).
In other words, more costs to an RFID deployment project, when
barcoding works well enough for most manufacturers. (Keep in mind that,
often, its the distributors that want to track items.)
At item-level RFID tags
running around 40 cents, it's not always financially feasible to use
them for low-ticket items. Pallet- and case-level tags tend to not only
be cheaper, but there's obviously less of them required for a shipment.
But the prices of item-level tags will go down. According to an article at Sterling Hoffman, Alien Technology
announced a sub-ten cent passive RF chip at some point in the recent
past. In fact, a Google search suggests the truth of the claim, but the
linked URL does not exist on Alien's website. There is, however, a
press release for a 12.9 cent EPC Class 1 chip. Still, RFID Times suggests that sub-five cent RFID tags will become commonplace, although probably not until 2013.
I
don't doubt that the sub-ten cent barrier will be cracked, and likely
well before 2013. It also helps that companies like Gillette recently
ordered 500 mln chips. Evan Schuman at Storefront Talkback
writes that 200 mln item-level tags will be sold this year out of a
total of 1.3 bln RFID tags, followed by 2.2 bln next year. Procter
& Gamble (new owners of Gillette - way to corner the razor market) is also conducting two RFID tests on their Fusion five-blade razors. (Which may explain why the darn things cost so much, and why I shave once a week now lol.)
These
kinds of large orders will eventually bring the price of all types of
RFID tags down. Unfortunately, most small vendors cannot currently
afford to use item-level tags. This financial limitation hampers
initiatives such as Wal-mart's plan to have all vendors eventually supply all their products complete with item-level RFID tags.
Alternatives
being looked into included both "light-based" tags as well chip-less
tags that created from thin-film transistor circuits and other means.
Of course, there's always the option of combining RFID with barcoding,
but that wouldn't let P&G know how many times a week I'm shaving.
