    Dear SIS Community.

    A credit card from Danske Bank -  type MasterCard KontantKort -  has been found on the premises.

    The card can be collected from the school's admin. office in exchange for a written note with the number of the card and a parent signature. This is to ensure that the card is not handed out to the wrong person.

    Kind regards
    The SIS Administation
