Also, you can find previous announcements of Hitachi's μ-Chip series. In 2001, evidently, they put out a 0.4 mm x 0.4 mm chip.
Not being programmable at all and just transmitting a 128 bit number would help get the size down.
Let's compare to a Monza R6 chip that was introduced in 2014, I think. This thing is 0.464 by 0.442 mm according to the datasheet, so quite a bit larger even than the 2001 read-only μ-Chip.
But it it has a two-way communication with the controller, and writable memory. You can enable password protection and such.
The newer M800 series is smaller: 0.247 mm × 0.362 mm, but still larger than the 2005 read-only μ-Chip. There are more features: fatter datasheet. Things like a privacy mode: tag remains radio silent unless it sees a specific 32 bit code from the reader.
You know how you can hold a totally unrelated RFID tag to a door reader and have the reader beep, indicating it has communicated with the tag? This looks like the feature that would prevent that. That could be useful.

So you could spray sticky rfid chips into an enemy’s hair, undetectable when scanned, and later on you could send the correct signal to identify enemies in the room. Later their hair would be trimmed, leaving no trace.
Aside from the cool privacy aspect, it seems like it would be cool to:
- Attach to insects to later use a detector to find their homes.
- Coat it and eat it to track your digestion.
- Use it in a miniature tornado model or wind tunnel along with a radio spectrograph to have cool visualizations.
- Embed in paintings, 3D models, clothing labels, and more to verify authenticity, get serial numbers, or track inventory.
- Drop a trail of them behind you so others can follow the trail and find you!
