rfid Technology - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Hi

I am looking for some technical help in regards to an RFID proejct I am currently working on

I am currently looking at an LF based (either 125 or 13.5 MHZ) for this application.

The issue is I need the distance of at least 4 to 6 feet.
For a passive system, I dont think its feasiable to work.
For an active system, it still needs to work at the same frequency.
Is it possible to design and active tag that still communicates at LF frequencies? Based on the same principle of communication as a passive tag?
I though about going to UHF, but the cost and issues assoaciated with it are not accetpable.

Any information would be great

Thank You

Robert Patterson
