I have read through a ton of the RFID topics. I don’t believe anything like this has been asked before.
I have setup several basic RFID readers before, but I now have a new project and can’t seem to figure it out.
I want to have a large “pad”. About 3ft. by 3ft. The goal is to allow for 1, or many ( up to 10 or so tags ), passive tags to be on this pad and be able to tell which ones tags are on the pad.
I have created a crappy version of the pad making my own antenna and it will read one, but not more than 1 tag. This is using a very cheap $5 reader I bought a while back.
I am open to making my own antenna, or buying one. I think the more important part would be the reader. One with anti-collision I am guessing.
The issue is I do not need “range” in the Z direction beyond maybe an inch or two incase 2 tags are on top of each other.
Mainly just need to read from the top of the bottom, and left to right on the 3ftx3ft surface.
It may not be possible, or they may be a better option than RFID. I do need to be able to tell the tags apart to tell who they belong to, so basic sensors for presence or weight won’t do.
This is for a kids game were making for a party, and each child will get a tag to throw.
Any insight is appreciated!!
