I shipped a product I built recently. My customer called me with "this is not in the buyable condition by any stretch of the imagination."
Turns out FedEX ran a forklift claw through the crate. I didn't know any of this would happen in transit. I could have used a Droptag to know what was happening. I could have braced for that surprise call. I could have started the insurance claim ahead of time...
Just EEPROM would be fine, as long as there was no user interface that allowed you to rewrite to the memory. After all, who's going to open the box, remove the tag, unsolder the EEPROM, attach it to something that can Write, know the storage method to write a fake file into the tag, solder it back to the board, back in the box and seal everything up. Yes, it could happen, but isn't really possible.
Plenty of RAM would work too, since power isn't likely to be removed and if it is you can assume that the board took a large shock.
Cabe, for the end user, is the purpose of this technology to query the device inside the sealed package before accepting / opening it? Basically, before you sign, you check your smart phone, and if the device reports high g-loading, you file a claim?
Bluetooth, an accelerometer, a little memory, and with that you can tell if your package was abused and when it was abused (which gives you a fair idea of where it was abused). Keep it cheap and you won't need to worry about making the tag writable for multiple use, and then there's no security concerns. At $2, it's cheaper than insurance for the package.
@a.saji- Yes investing on location shipping container would definitely be an investment which is worth. I think this is something that the government needs to interfere and get the shipping lines to use.
@eafpres- a good point, data security is a major concern for most of the devices we use. This too needs security to make sure that the program is not overridden. No matter how low the cost is people would be reluctant to use it without proper security features.
@mrdon- True a GPS device would definitely help to track, but I have had this question on my mind. How does the GPS location coordinates be uploaded to a location when it comes to international shipping. GPS needs GSM connectivity to upload the coordinates to a server or any other location.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
