Question: is a citizen card the same as an identity card

Answer: Yes, The Citizen Card (Portuguese: Cartão de cidadão) or CC is an identity card issued by the Portuguese government to its citizens. The card replaces several previous documents, including the Bilhete de Identidade (BI; Identity Card), Social Security card, National Health Service card, Taxpayer card and voter registration card, in one secure card. The Citizen Card was first issued in the Azores in mid-2006.
