A fob is a small metal device that attaches to your keychain. The linking chain may also be made of leather or cloth, it holds the keys together and prevents them from getting lost.
Key chains are often used for carrying identification such as a driver’s licence or bus pass. It can hold keys, coins and other personal items so they’re easy to reach when you need them quickly. You can attach sewing pins, golf tees and other things on the lanyard instead of using coins to activate locks at laundries!
