Lanyard

A lanyard is a length of cord, webbing, or strap that may serve any of various functions, which include a means of attachment, restraint, retrieval, activation, and deactivation.

In the military, lanyards of various colour combinations and braid patterns are worn on the shoulders of uniforms to denote the wearer's qualification or regimental affiliation.

Members of the British Royal Artillery wear a lanyard which originally held a key for adjusting the fuzes of explosive shells.

Lanyards are widely used with small electronic devices such as cameras, MP3 players and USB flash drives to prevent loss or dropping.

The Wii Remote wrist strap is a form of lanyard, keeping the device attached to a player's arm during the often vigorous movements involved in its use.

Lanyards are commonly used to display badges, tickets or ID cards for identification where security is required, such as businesses, corporations, hospitals, prisons, conventions, trade fairs, and backstage passes used in the entertainment industry.

Lanyards can feature a variety of customisation techniques including screen-printing, Jacquard loom weaving, heat transfer, and offset printing.

Lanyards with a breakaway feature are most often used in hospitals and healthcare clinics, schools, nursing homes, child care facilities, and factories that require employees to operate machinery.
