Finally, there's a gadget called Auto Finder that uses a transmitter left in your car and a receiver attached to your keys. It shows you a picture of where you are and there's a big red arrow to point you toward your car. With this app, you use your smartphone camera. An app called 'Car Finder' uses a visual technology known as 'augmented reality'. Then you go do your business, and when you want to find your car you go back to the app and hit the button that says 'find my car', and it points you in the right direction. When you park your car you open the app, and hit the button that says something like 'remember this location.' It uses the GPS feature to pinpoint your location. They are available for all the smartphone platforms and most of them work pretty much the same way. They have names like, 'Where's My Car', 'Take Me To My Car', and 'Find My Car'. Well, there's an app for that actually several. It also happens with rental cars when you forget what the car looks like. Most of us have experienced walking out of a big shopping mall and not remembering where the car is parked, especially if it's a place with which you are unfamiliar. So as long as you can find just one of your FOFA activated items you can theoretically locate the rest. The difference is that all of FOFA's receivers are also transmitters. That uses a small receiver as part of a glasses lanyard.

It has a variety of receivers including flat ones for your wallet, key fob style, and the only one I've found for retrieving eyeglasses. Find One Find All, or FOFA, can manage six devices as well. There is one product I've found that may have the best solution. Misplace that and you're out of luck in finding any of the six things electronically attached to it. But there is one big problem with most of these systems. Prices generally run from about $25 to $45 for a transmitter and a set of six receivers. Among the brands we found available on : EZ-Find, Smart Finder, Click 'n Dig and Orliv Smart Finder.

There are a number of key finder sets on the market, many of which come with multiple receivers so you can tag other important items like your wallet, or remote controls. Sometimes there's a flashing light as well. Push the transmitter and an alarm sounds on the key fob. It's easy to attach a small electronic key fob to your keys.
