Dammit Jim! Wherez my wallet?

Remember the mainframe concept of consolidation? Where all the CPU power, rules , data are all in one central server - and if that crashes all hell breaks loose? Well the way I maintain my wallet is not too dissimilar to that. All credit cards, cash, membership cards, IDs and licenses are all stored in one consolidated wallet - which makes for great efficiency in access.... till I lost track of it yesterday.

Therez an entrepreneurial idea - as soon as the distance from the wallet to the person who owns it increases by more than 10 yards - there is a mssg going on to alert my laptop, smartphone abt its location.

Question is - Whatz the business model? How does one make money out of this? For one - not losing a wallet would be a good starter.
