Abstract: The instant invention is an arrangement wherein a set of devices are enabled to signal each other either individually or as a group, and are attached, inserted, or integrated into various items in order to locate such items when they are lost, or to secure them, or otherwise keep track of them; or also any arrangement and deployment of electronic components, modules, etc (one example of which might be standard RFID chips such as are used in inventory control), such that a group of important but easily lost items, (such as wallet, keychain, calendar, and briefcase) can signal to one another so that a lost item can be “beeped” so that its whereabouts can be discovered. Additionally, the devices may be configured to signal the others if or when mutual contact is broken.
