itsme is a free app that allows you to securely log in, register, sign and pay in various online apps using a single PIN of your choice.
It also means you'll never need a card reader and all your different passwords again to carry out those operations. At present, the app can be used at KBC Brussels, Doccle, Bolero and Randstad. It is also useful for submitting your tax return via Tax-on-Web.
itsme is a Belgian Mobile ID initiative involving 4 big Belgian banks and the Belgian network operators.
