A lanyard is a rope or cord exclusively worn around the neck or wrist to carry something. Usually it is used where there is a risk of losing the object or to ensure that it is visible at all times. Aboard a ship, it may refer to a piece of rigging used to secure objects. Alternatively it is a length of cord or wire with a hook at the end used to fire an artillery piece, or to arm the fuze mechanism on an air-dropped bomb by pulling out a cotter pin (thereby starting the arming delay) when it leaves the aircraft.

Simple lanyards made of braided fabric with a clip attached to the end are used frequently in retail and business situations for holding name badges. The typical arrangement is to attach a plastic pouch with at least one clear side to the lanyard, with the person’s name badge facing the front and occasionally small items such as business cards, pens or tools stashed behind the badge for easy access. Such lanyards can also be used as keychains, particularly in situations where keys can easily be lost for lack of storage, such as gyms, public pools and communal showers.
