I thought RFIDs, like toll road cards, could only be read when the
reader was 10 or 20 feet from the chip. That there was no battery or
transmitter in the card and it worked by resonating with the
transmitter in the reader.

So how could they know if the kid was home?

Even though other sites report it, this story sounds fishy to me.

track them wherever they go. These chips are always broadcasting so
anyone with a reader can track them anywhere,” she says.

Just point out the potential health issue from exposing all those
growing kids to the electromagnetic fields from long range RFID
scanners. The normal door access ones that read from a couple inches
have negligible fields, but the ones that can read from feet away have
substantially stronger fields since it is those fields that power the
RFID chip when in range.
