uniquely identify someone walking (or jogging) by
Another idea that came to mind is using a magnetometer to detect when a person is in range.
What I want to do is be able to uniquely identify someone walking (or jogging) by, let's call it a "base station", at a range of 1 meter with a budget of around $200 for a single person solution.RFID comes to mind as a possible solution, but my reading indicates that the 1m range becomes expensive. I was thinking that having an active RFID tag would work, but those readers seem to be expensive as well. Does anyone know of any RFID solution that might work?
Why does your range have to be 1m? An RFID sticker tag inside a shoe and a reader on the ground should be able to reduce that range considerably. Even better would be two sticker tags, one in each shoe. Doesn't matter if they are not both the same ID, as you just want to be able to identify the person. Place the reader where the path is narrow.
This is an interesting idea...How fast is the acquisition time of one of these readers if the shoe passed over the reader quickly? You'd have to ask the manufacturer or supplier. I've no idea.Could I make the reader "long" somehow? That is to say, more like a pill shape vs. spherical? Or would I need a couple readers next to each other to cover a 3 foot wide path?
