Use your electronic identity card on the web
beID stands for "Belgian electronic identity": the chip on your Belgian identity card and the software that lets you use it. With your eID and a card reader you can prove your identity online and sign documents with legal validity.
To use your eID on a computer you need three things: the official eID software from the Belgian government (free at eid.belgium.be), a card reader, and — to use your card on regular websites — a bridge between your browser and the card.
The beID Helper is a small, free program that provides that bridge: supporting websites can read your identity data or request a signature through the helper — always only after you enter your PIN. The helper runs entirely locally on your computer; nothing is sent to a server.
eID is the card itself: your electronic identity card. beID is the name commonly used for the card together with its software. itsme is a separate smartphone app you can also use to log in — convenient, but for some uses (such as a qualified signature with your card) the eID itself is still required.
