We have noticed this happening from time to time but without the extra
information you seem to have been able to gather we have learnt to live
with it. We have been putting it down to faulty tags and reconfiguring
the tag etc.
Sorry I can be of no help

Subject: False alarms with our detection gates
We are running out of ideas for how we can sort out a lingering niggle
with our RFID installation. The gates are normally very effective and
well-behaved, but they do have a habit of false alarming. Luckily the
reporting software allows us to show this (see graph below). Wednesday
is definitely the worst day. This morning it had alarmed, with no
secured item detected, 9 times by 8am. The error message from one of
the times this morning is also below.
We have had our supplier looking at this, and also the local Estates
staff. We have asked them to check for any machinery nearby in the
plant room above us, and also asked in the Ward downstairs to see if
there is any piece of equipment used more on a Wednesday. We have had
no potential solutions come to light.
I wonder if anyone else has had something similar in their RFID
installation, and might be able to offer us a clue?
