The 'usuario' number is your user number and the 'clave' is your password number.
The card with all the numbers on it is your PIN card. Every time you want to make a transfer, make a payment, cancel a payment etc, then they will ask you to enter the value that is next to the number they have given you. It's an excellent way of making sure that nobody can log into your account and conduct transactions, as each card is unique.
You can go directly to thier site at www.cam.es
Once there, on the top left hand side you will see 'Idioma' which means language, click the down arrow in the box underneath and select 'Welcome'.
Then click on 'Usuario' (user) and enter your user number.
Lastly, click on 'Contrasena' (password) and you will get a pop up box with numbers inside it, just enter you password by clicking these numbers and finaly click 'Aceptar' (to accept).
