Anyone got experience or knowledge if multiple Paper Security Labels (RF 8.2 Mhz) can be counted accurately at the same time? For example, if I put 10 of these labels on top of each other or beside each other, can I still count them reliably?
Do you have a link to the exact technology and labels being used? it sounds like this is a bit more industrial so would be worth messaging the company that products these labels.
Short answer - no. What you are talking about is something called “Multiple Tags In Field” (I think - it’s been a while since I was last involved)
Longer answer - yes with very complex (read expensive) equipment. I have seen a system where consignments of items - each tagged with their own unique RFID tag - were passed between two large detector arrays, and all items were inventoried.
But for any small and handheld reader - you may get 1 or two, or none.
Noting that you seem to be just (!) trying to count quantities of this style of tag - I would guess that you would be against the same problem of separating them out for counting.
(back story) We were looking into a way to scan a piece of equipment and check whether all items listed on a special Bill Of Materials was installed … . . . . … could not do it, so went back to reading individual unique barcodes (tedious but practical) on the listed parts.
@Murray125532 thank you for your reply mate. One time cost will not hurt me, but reliability is really what cant be compromised on for this particular project. The tags are the security RF tags, used in stores for theft protection. Does it make things clearer?
Clearer - yes, but I don’t know of any tech that could help you.
As far as I do know, the anti-theft operation simply detects a signal resonance from a tag as it is excited by the signal generator systems at the doors. One tag or many, the result is the same, the resonance triggers the alarm.
I have only looked into the tech around RFID tags that can hold data and be activated and read by the scanner systems. I don’t think that applies to the simpler anti-theft tags.
