ID cards, plural, for Watch, because since the government is the one managing basically everything in their life for experimental studies, Watch has about five fake IDs at all time :D which is very convenient depending on what age you want to be for which circumstance! (no one knows their age exactly, so anything goes!)
And also do note that in many places, like Belgium, you need to be 16 years old to drink, and not like in the USA where you have to be, you know, 91 years old for your first beer ;)
