According to the BBC, the biggest user of RFID tagging is the US military. Why am I not surprised? smile

When i was at the equipment libraries forum in Blackpool the other week RFID was discussed and it got me thinking .... Really! I hear you saying... I do it occasionally (Think). boggle

Richard said in a previous post:
Quote:
Device manufacturers who eventually introduce their own RFID tag that can talk to other manufacturers RFID tracking system, that uses an open standard, may produce their own built-in RFID system that can pass-on more data concerning current status and location, plus service and calibration data, etc.


I think this a very exciting concept - having information of where it is, who it is connected to, what is it doing/delivering, or... which cupboard is it in!

I have yet to see a manufacturer that has built in RFID - I think they have been caught napping (or is that me) sleep

Can anyone out there enlighten me whether they have devices with built in RFID? With the NHS going wireless - it seems like a major market advantage to me. smile

Yes, you've been caught napping, I'm afraid, John. What about GLIB? smile

So, two years on, what has become of Rigel's Brain Cells? Has anybody given them a go? smile

A news item on self powered and small RFID tags. So why are the ones for medical equipment so big? boggle
Robert


My spelling is not bad. I am typing this on a Medigenic keyboard and I blame that for all my typos.

I think it's because they may be active, i.e. internally powered, with relatively long life-spans and the ones I've heard of for medical use produce radiated power equivalent to that of a mobile phone for very short periods.

Indeed so.

RFID is available in two flavours; active or passive.

Active tags have an on-board embedded power supply, i.e. a battery, whilst passive tags obtain their power from the reader and can therefore be manufactured in a variety of small sizes.

Active tags have a limited lifetime due to the on-board battery, whilst passive tags have an unlimited lifetime.

RFID infrastructure is also something that needs to be carefully assessed such as operating frequency and reader location etc.

RFID is not a new technology having been used in retail for inventory tracking for some time now.
Wal-Mart have been one of the largest RFID proponents with Tesco and M&S also now using it however, it is new within the medical environment.

As Richard says, the RFID tags used in the article are passive. Whereas active tags require a power source (battery) which obviously makes it larger.
