There are a few simple handhelds that read tags, along with a some simple 
tiny usb readers that you can plug into laptops and such.  Purely to read 
tags, they won't save or erase the data on the tag.

Thanks,

Jennifer

Is there any date - eye-readable as to the date of manufacture, and/or
encoded on the tags on date first encoded - to check all this?

And are there any 'cheap and cheerful' read only, store nothing,
handhelds (like the TfL devices used by the Revenue Protection officers
with Oyster cards') just to see what's on the tags and test that they
are working without having to go back to a fixed PC or an expensive
hand-held designed to download data etc. etc.

Hi all



Of the 31 libraries in the survey (still ongoing) that have reported
problems with tags deteriorating over time most have had problems with
CD/DVD tags. Quality of manufacture has been mentioned in only two
instances. Most also report that the number of failures is not
sufficiently large to be considered a major problem.



There are 450+ replies to analyse - and there are certainly duplicate
entries from some organisations - but even allowing for that 31 doesn't
sound too alarming. From bitter experience I think the real key is to
buy from a supplier that understands the life cycle of a library book.
The tags used for libraries are also used in supply chains where
longevity is not such a big concern - so poorer quality materials can
survive long enough to move goods. Libraries are a little bit
different...



As Jennifer suggests there may be a case for "refreshing" tags
periodically by waking them up. Using a hand-held to take inventory of
all stock would achieve this - and deliver useful data at the same time.



Using RFID for security only would present the same problems as using
them for anything else. RFID security is driven by data - just as all
other operations - so if you can't read it, you can't use it.



Hope that helps. Survey closes tomorrow so expect first results next
week!

Hi there



We currently don't use RFID in any capacity but want to explore the
technology for security purposes.  Would the issue of tags losing their
read range over time also be a problem for RFID book detection security
systems?



Thanks

Tags can lose read range and data over time.  In a well used library,
despite the 'factory tested' guarantee of 10yrs, on items going home
with different people (in the bath, warm rooms and so on)around the 4/5
year mark is a more appropriate for tags.  There are more styles of tags
and information you can look at, such as plastic coating and operating
temperatures, may help prolong the life span of the tag.  Also depending
on your supplier and SLA, you may need a service.  Most UK IT
departments have a technology refresh, every 3-5 years so it might be
worth asking if your supplier could look at refreshing after running
some diagnostics?



Thanks,



Jennifer

I've also heard of some tags losing read  range over time.  It seems to
be a limited situation.  Can you associate the problem with any
particular tags (perhaps a particular batch purchased from a particular
vendor)?

Dear Colleagues,

Our library has been using RFID since about four years now, and our
automated check-out points are getting less sensitive.
More and more it complains that returns are not complete (book+CD for
example), or that only four of five books from a pile get registrated.

Does any of you have experiences along those lines?
How do you maintain/upgrade the RFID machines to keep them on their
toes?
Hints and tips much appreciated.

Kind Regards
