Gosh you
lot are a reticent crowd. |
Over the past
year or so I have basically been writing about 'change'. Well, that's
fine. With the deregulation and retail competition threat being a good example of the former and the evolution of expanded POS use being a good example of the latter. In these pages we have canvassed real or perceived change factors covering a multiple subject list. Alphabetically we have tried to convey bits and pieces regarding: · barcodes Be nice to
think that someone is keeping score and is measuring the predictions
and other opinion pieces with the 'real' world experience out
there. So, I thought
it is time to get way out front and talk about issues that are
almost virginal in their present state. Radio Frequency Identification - RFID. A subject with as much disinformation, mythological and demonic threats and bad hair day emotion as any human nature watcher could ever wish for. Ah, bliss, even worse than the good old Australia Card, smart card brouhaha (which is on it's way back too, but that is another story). First we have to acknowledge rule 1 to rule 10 and rule 101, which is refer to rule 1 about data capture technologies. It is NOT the technology that is the issue, it IS the data. Even after twenty years, people still refer to the 'barcode' as if a barcode is a 'thing'. It is no such thing, merely ink on paper representing information. If the information, usually a number, is wrong then the 'barcode' reading will be wrong. The barcode is only a means to capturing data electronically without re-working the effort by re-keying with all that keying brings about. Think about
it buzz word terms. The printed number represented by bars and
spaces is dataware, the barcode reader is hardware, the decryption
is software, the transaction is middleware and the human operator
provides the wetware component. (we are mostly water - get it?).
So simple
that often smart folk can't see it. No such thing
threatens anyone in the use of these tools in retail applications.
Not, that
is, until we have a chip in our left ear! And, what
is even more galling is that technology, alone, is no threat to
anyone. Take a faxed
discharge summary compared to the improvements from the coming
electronically transacted message. Oh, I know,
there are real threats when technolgy is implemented incorrectly
with little or no protection, standards and so forth. So, now that is off my chest and is clearly in black and white terms lets return to RFID. Let me tell
you what you need to know in three words - a long time. It will be
a very relatively long time before RFID becomes a ubiquitous,
retail community pharmacy, technology tool. In simple
lay person terms this is because of cost, performance and above
all convenience. Got it? Picture the
last time you bought expensive clothing. The other
underlining parameter is cost. A simple rule
would be say data regarding a costly asset is better processed
by RFID than a consumer item. Another possibility,
closer to home, is medical misadventure - in error minimisation
in hospitals. Electronic patient tags and electronically tagged
dosages, for example. The major
performance difference is that some RFID tags can be read/write.
The most commonly
cheap version of an RFID label is the microchip now, mostly, mandatory
for animal registration. In terms of
functionality there is one advantage - as in RFID v barcode. And
it is not distance. It is invisibility.
Picture the most commonly expected retail sector application now being tested in the USA and elsewhere. Tracking freight,
pallets, containers, perhaps cartons of sensitive, costly, merchandise.
Whereas the RFID label can be protected from physical contact and thereby 'hidden' to ensure more end-to-end security of tracking. Picture again! A fork truck
driver who has to While we are
on the fairy tale bent lets put the other lulu to bed. Well, maybe
I can't sell you the Sydney Harbour Bridge, but would you like
another one? Think about
it? So there you
have it. Or if you
meet any item of wetware spruiking RFID systems as being ready-to-go
for retail pharmacy is a) from planet Org, or
