It would be a shame to lose this. We were discussing the idea on OVDB. It was Enelysions idea.
Interception detection chips. They consist of photovoltaic cells, volatile memory and battery powered extended range RFID chips. The volatile memory contains a secret 'not compromised' string and is attached to the RFID. It also contains some simple programs, primarily a program that broadcasts the secret string after some time delay (alternatively broadcasts the secret string in response to another secret string being broadcast to it, although this requires broadcast of the pick up agent and may deanonymize them if LE are waiting for them with radio frequency analysis equipment at the pick up location). The device is set wirelessly after being placed into a closed package. If the photovoltaic cell is triggered by light, for example when customs opens your package, the secret string is removed from volatile memory so customs agents can not reconstruct it. After some time delay, the extended range battery powered RFID begins to transmit the secret string, or perhaps begins to transmit a pseudo random pattern that uses the secret string as the seed (this will allow for verification of the secret string being present and make it so that law enforcement can not rebroadcast the secret string if they identify the chip and rebroadcast what it transmits after the time delay runs out).
Now you can tell if your package was opened prior to picking it up from your fake ID box, merely by analyzing the radio frequency spectrum near your box location. Extended range RFID can broadcast signal significant distances, and as no broadcast is required to activate the interception detection chip it will be very difficult for law enforcement to identify anyone performing such radio frequency analysis near the box store.
Additional detectors / triggering mechanisms can also potentially be integrated, such as oxygen sensors with the chip vacuum sealed with drugs, or x-ray sensors, etc.
This sort of defense is strongly related to concepts from the field of measurement and signature intelligence, MASINT.
Such chips would likely cost under $10 each to create, although some custom programming would be required to configure them. As far as size goes, they could be pretty small, probably about the same size as a quarter maybe a little thicker.

Very clever idea.

It is a good idea but the person who made such a chip would have to be someone you trust. LE could create such a device and then hope that it makes it to sellers. They could use the device to gain information that they may not have access to otherwise. Its always a bad idea to use something created by someone you dont know or dont trust..........even drugs............even technology.

Obviously you would want to make them yourself. You can buy all the components for it with out any problem, but putting them together and making them do what you want is the part we haven't done yet. Enelysion was talking with some people about making an open source design and software required for people to make these themselves.
