Tracking Chip?

[tyanque]

Is there anything available to buy online / in stores like a chip that you can put on a device so you can track it down if you lose it, I don't mean GPS. I ask this question because I am always losing pen drives and it would be useful if I could find it easily rather that having to look ever where in the house :p.

Thanks

They have beeping locators for keychains for when you lose your car keys in the house. If your pendrive has a keychain hole on it you could use one of those.
