The master device utilizes a programmable database for up to seven slave items.  The device itself can be built into many different systems and cases.  For instance, a cell phone could affordably make use of the Commo Neo.  The product could also be built into a belt or a wrist watch.  The possibilities are endless, as this device is a hermit crab that can be put into many different shells. 

Although there are many reminder-systems on the market, none of them notify the user that an item is missing.  The Commo Neo, on the other hand, continually monitors the distance between a master and its slaves in a Bluetooth network.  When the master device (carried by the user) detects that one or more of the slaves (a tag attached to the item being tracked) are out of range, the device alerts the user and notifies him/her that an item has been left behind.
