The principle of RFID (Radio-Frequency ID)
tag tracking is that the tag can be read
remotely from several feet away. Thus, if
you carried such a tag around with you, it
would be relatively simple to track your
movements wherever you went. Some
people are nervous about the privacy
of carying such tags or, for
example, having them embedded in their
This idea reverses the
usual model of how these tags work.
Buildings, bus shelters, train stations,
businesses would be tagged with RFID
tags and individuals would carry around
readers, perhaps as functions of their
PDAs. At the end of a day you would be
able to see a list of all the RFID tags you
had walked past that day. This would show
you where you had been, the bus you
caught that morning, which clients you
had visited, even perhaps which rooms in
your office building you visited. This
information would be yours - there is no
way the RFID tags can know who is
reading them and so there are no privacy
have an incentive to tag their premises so
as to get a mention on your personal 'log'.
This idea might help to remind you what
you had done on a particular day, or help
you to link notes you had taken to your
location when you took them and the
people you were talking to.
||I can see a variation on geocaching coming from this.
||Proliferation of pocket-sized long range readers might cause some security concerns since some people do carry around RFID tags in the form of building access/security cards.
||Hmmm, I don't remember walking buy a business called "Cheapest Viagra on the net!" today. Oh, no....
||Where have you been?!
Its all right here, honey.
<mumbles under breath> Whew! Good thing I passed this off to my friend this morning. </mub>
||Yes, [krelnik], you'll need a spam filter
on your RFID reader. Howwever, the
RFID tags could deliver money-off
vouchers etc. as well so there may be
some benefits from the more unsolicted
||I noticed all your ideas were in the past tense, but this would be so useful if you wanted to use public transport in a foreign city (for example, the underground railways in China, or the bus service in South Korea), or check items in a museum.
If there was a wireless link it would be great. It could even allow you to enquire about the details of goods in a department store, with the appropriate database.
||The portable reader part may prove somewhat difficult to impliment, or so I've been led to understand...
||All the same, there's plenty of good fun available in this idea... and larger vehicles, which might be able to use more powerful, and therfore longer range readers could have some other applications.
||This would need to be a very cheap
product as it doesn't provide a fuction that
can pay for itself. It's a good idea for when
money is abolished. Wait for the age of
Star Trek to come around. Long Live Picard
||I'm just not seeing this as an advantage over GPS.
