Re: RFID reader design

I am trying to build a RFID reader for passive RFID tags like
http://availabletechnologies.pnl.gov/securityelectronics/rftagsdescription.stm.
These tags has got read/write range upto 10m.

My reader must be capable of reading tags at a minimum distance of 6m(
also the maximum).

I got few questions regarding this

1) Is it possible to read passive tags at a distance of 6m

Not likely.

2) Is it possible to build this reader.

3)What would be the size of reader

4)What would be the power requirement of this reader

5)Is it possible to detect direction and distance of RFID tag from the
reader


It would have to be more than an RFID tag. It would have to be able
to report back directional data other than merely the RFID packet.

Too many systems to itemize here rely on the 'unique ID' of an RFID token to grant access to a system or building, and, in the case that these tokens are based on 125kHz or 134.2kHz standard tags, many of them may be vulnerable to relatively simple cloning attacks. ...
