Hi all,
I'm researching RFID for an application which would require the following:
* Detection range of about 2m (actually, what I'm really interested in is detecting any tag leaving through a door, kind of like the ones in commercial stores for security
* Need to be able to detect multiple tags at a time
* No need to write to them; just read an ID
* Passive tags
So far, it seems that UHF is the frequency I should be targeting (due to the range), but all readers are more than $200 (and I want to make this cheap).
Does anybody know of a cheaper reader in the market, or some other technology (maybe a weird antenna design) that would allow me to use the cheaper readers (125KHz or simillar)?
Thanks in advanced for any reply,
- Nicolas.
