Some fobs are attached directly to the item, while others are added to a key ring. Each fob can be color coded to represent a specific tagged item - red for a car key, blue for a house key, green for a TV remote, and so on.
While many RF key finder systems only include one receiver, a Bluetooth system can handle additional smartphones with the installed app. The phone will ring if it is within range of the two-way transmitter. The fob can also be used in reverse to locate a missing phone. Some Bluetooth-enabled key finders can use GPS information to pinpoint the exact location of the fob. When a tagged item is lost, the app sends out a signal through the phone and listens for a response. The other system uses Bluetooth technology and a special app for smartphones. When the searcher is within range of the fob, the transmitter displays a light cue and/or emits an audio tone. An RF key finder uses a transmitter that sends out a specific frequency tuned to the fob attached to the lost item. The older of the two is radio frequency or RF, and it doesn't require any smartphone app or Internet connection to work. Most key finder systems are powered by two different technologies. At the top of our list is the Tile Mate Key Finder, which is a Bluetooth-powered system with two-way communication and a generous 200-foot range.
Others offer two-way communication, so a key fob can be used to locate a missing transmitter or smartphone. Some key finders offer a generous supply of tracking fobs, so you can tag a number of commonly misplaced items. If you are in the market for a new key finder system, please read this helpful shopping guide. RF systems do not require any Internet service, but Bluetooth-based systems provide more precise results. Both systems involve applying a special tag or fob to the object and using a transmitter to pick up the tracking signal. There are two common types of key finders: one using radio frequency (RF) technology and the other using a Bluetooth-powered smartphone app. One popular solution to this problem is an electronic key-finder system. Small but vital possessions such as keys, remote controls, and wallets are easy to misplace, and they can be nearly impossible to find during a frantic search.
