I wonder if you could create a chip that could break the passport reader system. That could really disrupt things, so hopefully that’s not possible.

You can transmit arbitrary data in certain steps of the passport reading process. The possibility of disruption depends on whether the reading system has bugs exploitable by the incoming data.

I've seen crashes in PKCS#11 drivers when reading cards with malformed data. So, the possibility, in theory, is always there.
