In the 1980s and 1990s the term described [RS232] or [LPT] attached appliances acting as CopyProtection for high-end applications. [Dongle]s in this capacity acquired the image of being unwanted liabilities, not only because of their purpose, but also because of a whole slew of technical problems. They either took up a precious port or caused problems with other devices connected thru them. It was usually impossible to daisychain [Dongle]s, should several applications require them. As if all that was not enough, their connectors would often start failing within short time if un/plugged too often. As a result, these days CopyProtection [Dongle]s are a rare sight. |

The term however is being recycled as for [USB] attached, highly specialized devices, often containing RandomNumberGenerator~s, secure key stores in cryptographic systems, or suchlike. |
