hi everyone
i am building some project and basically i want to tag somethings like wallet, pda etc
and be able to determine if a person is carrying those tagged things from a reader by the door as the person passes through the door.
i need a reader which reads in a range of about 1m
i have found so many of them on the net with a cost btn &400-2000 which is too much for my budget.
does any one know of a cheap reader which can read in this range?
or have a better idea of how to do this?
