A fob, or more commonly called a key fob, is a small security hardware device with built-in authentication used to control and secure access to network services and data. The key fob displays a randomly generated access code, which changes periodically, usually every 30 to 60 seconds. A user first authenticates themselves on the key fob with a personal identification number (PIN), followed by the current code displayed on the device.
Key fob is also a word used to describe a key chain and several other similar items and devices. The word fob is believed to have originated from watch fobs, which existed as early as 1888. The fob refers to an ornament attached to a pocket-watch chain. Key chains, car starters, garage door openers, and keyless entry devices on hotel room doors are also called fobs.
I like the Wikipedia version:
A key fob is a generally decorative and at times useful item many people often carry with their keys, on a ring or a chain, for ease of tactile identification, to provide a better grip, or to make a personal statement. The word fob may be linked to the low German dialect for the word Fuppe, meaning "pocket", however, the real origin of the word is uncertain. Fob pockets (meaning 'sneak proof' from the German word Foppen) were pockets meant to deter thieves and a chain was used (called a Fob Chain) to attach to items, like a pocket watch, that you would place in them.
Fobs vary considerably in size, style and functionality. Most commonly they are simple discs of smooth metal or plastic, typically with a message or symbol such as that of a logo (as with conference tchotchkes) or a sign of an important group affiliation. A fob may be symbolic or strictly aesthetic, but it can also be a small tool. Many fobs are small flashlights, compasses, calculators, penknives, discount cards, bottle openers, security tokens and USB flash drives. As electronic technology continues to become smaller and cheaper, miniature key-fob versions of (previously) larger devices are becoming common, such as digital photo frames, remote control units for garage door openers, barcode scanners and simple video games (e.g. Tamagotchi) or other gadgets such as breathalyzers.
Tchotchke (/ˈtʃɒtʃkə/CHOCH-ka) is a small bauble, doodad, doohickey, gewgaw, gizmo, goolya, kitsch, knickknack, lagniappe, swag, thingamabob, thingamajig, toy, trinket, whatchamacallit, whosie-whatsit, widget, etc. Depending on context, the term has a connotation of worthlessness or disposability as well as tackiness, and has long been used by Jewish-Americans and in the regional speech of New York City and elsewhere.
The word may also refer to swag, in the sense of the logo pens, key rings, and other promotional freebies dispensed at trade shows, conventions, and similar large events. Also, stores that sell cheap souvenirs in tourist areas like Times Square, Venice Beach, and Waikiki Beach in Hawaii are sometimes called "tchotchke shops."
My package came in the mail today. I ordered in July and picked up my 2013 in September. I can always use another key holder.
