[QUOTE="JMN, post: 309286, member: 8469"] I am afraid you have a few misunderstandings of technology. Cell phones can not get tracked when the device has no charge whatsoever. The systems know where is was when last powered. Modern Iphone and Android-based devices do not fully turn off when you turn them off. This is why they can be turned on without an actual switch, but rather a momentary pushbutton. Just like the phone is always listening otherwise it wouldn't hear you say "Hello Google" or "Hey Siri". Edit: I believe you are thinking about something like this: [URL]https://dentureid.com/[/URL] Unpowered devices are capable of communication. You likely have used them without knowing. The anti-theft tags on clothes and electronics, for example, have RFID tags. Sadly these are not the solution which you seek. Short of an unhealthily high amount of EM output from an RFID scanner there is no way to track something more than a few inches that does not have its own power source. That is why you have to tap your card to the checkout or gas pump. It has a large antenna coil wrapping around and around the card and still needs a very short distance. There are ways for nefariously purposed endevours to read data from non-powered RFID as in credit cards from up to 300 feet, but this requires knowing where the card is and aiming an antenna appropriate for the task. For an alternate idea, a local demetia ward gives the patients their dentures with their meals. It's far less than ideal, but it works. And sadly, most get no visitors to notice whether they are wearing their denture or not. This same ward gives the patients a "Very special bracelet", as they are told, which has an RFID tag embedded and a reader in the elevator does not permit it to close the doors while a patient is near or inside the elevator.
