Accordingly, a Brazilian national may apply for and be issued Citizen Card in the same style as would be issued to a Portuguese national, except that the "Nacionalidade" (nationality) field shows "BRA" to indicate the bearer's Brazilian citizenship, and the back of the card carries the supplementary remark "CIDADÃO BRASILEIRO AO ABRIGO DO TRATADO DE PORTO SEGURO - BRAZILIAN CITIZEN UNDER PORTO SEGURO AGREEMENT". Additionally, because Brazilian citizenship alone is not sufficient to allow a person to make use of the European Union's provisions for the freedom of personal movement, these Citizen Cards are marked "NÃO SERVE DE DOCUMENTO DE VIAGEM / NOT VALID AS A TRAVEL DOCUMENT", instead of the machine-readable zone that would be found on a Portuguese citizen's card.
