Documento de Identidad (Uruguay)
The back of the card had information like nationality, date of birth, when the card was given, and when it would expire (usually 10 years after it was issued, but if you got it after you turned 70, it was valid for life, and for kids, it was valid for five years). It also had a thumbprint of the right thumb and any important notes. Since 2010, it also had a photo and a barcode.
