I'm a software guy so a bit on deep waters here so I thought I'd ask here. :-)
I'd like to understand if it is possible to have an RFID tag with the following properties:
weight: a few grams, size: around 5mm in diameter, length can be a few centimeters price: as cheap as possible range: a few meters or more
A person would then have a reader and walk around to find the items that have the tags on them getting a sound when a tag is in range or even better knowing somehow how close an item is.
Is this feasible with RFID? If not, where does it break?
Is there a better technology to use? I.e. have some kind of small and cheap "thing" to put on items that later can be used by a reader to find them?
Thanks in advance!
