Quite simply its a normal RFID, with an additional, grid of fragile wires that will break when you try to lift the tag out of its place.

The next time you read the RFID, the RFID will give out its ID and also check the status of the sensing wire.

If the sensing wire is broken, it will append a 'tamper sensed' code to the reader.

Could you describe a use-case?

perhaps you can have it 'seal' documents, e.g. court documents. (There is massive amount of documents that needs to be monitored, and ensured it is not tampered)
