A Brief History Of The Key Finder
There have been several versions of the key finder developed over the years. The first versions were activated using sound such as a clap or a whistle. For instance, if you lost your keys in the house, you would only have to clap loudly and listen for the beeps. Unfortunately, this wasn't a fool proof method. If the keys were too far away to pick up the sound, then you would be out of luck. Also, any loud clapping or whistling sound could set off the beeping, even if you were carrying the keys in your pocket.
These are still sold today even though they are dipping in popularity due to more advanced versions.
The second type of key finder developed was the Radio Frequency key finder that operates on a radio transmission. These are still sold today even though they are dipping in popularity due to more advanced versions. The biggest problem with the radio frequency key finder is that if you lose the base unit, you need a key finder to find your key finder.
The second generation key finder was patented by Cheryl J. Skeffington and Kathy S. Walker in 1998. They filed the patent under Key Buddy, Inc and proposed the key finder in which a button on the base unit was used to locate the keys or other item attached to the tag.
The third type of key finder was developed on a peer-to-peer system. This meant that any part of the device could act as both the base unit and the tag. You could attach these tags to each important item: smartphone, keys, wallet, etc and if you lost one, you would simply use one of the other items to locate it.
Now, with the rise of Bluetooth technology and smartphone apps, these systems are becoming less popular in favor of convenience.
