Can anyone be so kind to explain how it Works the presale tickets to
Barcelona one day before the general sell.

i read thet tickets will be sell via App

is it far ?

Is it just for people with memberships cards?

Maybe ask in the Barcelona thread?

I read it but it does not specifies who is abke to but them but there is a presalw one day before general selling.

Everybody that knows the link the RS app gives is able to access the presale.

Is it needed a password?

No.
