Need to know if there's something like an RFID chip that comes with a light as a visible location marker, doesn't require batteries or any power source to activate it. All u need is a corresponding device (which can be battery powered) like a car remote to signal to the chip to light up for 10secs.
Is there such a device around? If so, where can I buy it?
The idea is to paste the chip (which has a size limit of a 20cent coin) permanently onto a wooden marker which would be placed hidden amongst hundreds and thousands of smiliar markers and to identify the marker easily after 5yrs, 10yrs, 20yrs or 100yrs.
That's the aim.
