rfid Technology - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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
