Not trying to cause a ruckus, but I've worked in several Latin American countries that require citizens to have a national ID card, normally called a "cedula de identidad". It's used, well, like a national ID card. They generally ID them with a description, DOB, and place of birth as a citizen of that nation, period. Sorta a primary means of ID when someone from the gov, cops or any branch or organization needs to see ID. We generally present a license or mil ID or something with a photo; they present a license or anything, and then get asked to see their cedula if the person is still curious. For example, in Central America, they have a problem with illegals--cedula's help ID who's a citizen and who isn't. Like any document, including passports, there is a lucrative trade in false cedulas. In one country I worked in it was known that fake ones could bought for a price. Not saying that a national ID could not somehow be abused, but in the several countries I've worked in that uses them, I've not seen it happen. It they want to control citizens they ain't real subtle about it down there; cedula or no cedula. To tell the truth, I can't see how a national ID could be used against the populace here; as noted by many above, most of us already have more than enough info on record with the gov. Ain't many of us that aren't in the records starting with a birth certificate and then on up. I figure for 25 years I carried and used a Military ID to identify myself, and still do as a retired guy--and proudly I would add. I also use my license or my CCL, depending. When I travel overseas, I use my passport with that big eagle and United States of America on the cover of it--and proudly I would add. My opinion on issue of National ID cards? May have some utility, but hard to quantify. Good forgeries will be done by well funded bad guys, and hard to tell from real ones without expensive high tech equipment that will not be used generally and certainly not at airline counters. Hell, the current photo ID check at the counter is a joke. Why would a national ID card check be any better? Might be OK to help ID illegal aliens who can't afford a good false one. Will they be used to control the population? Personal opinion is no, not needed. So in wrap-up; good use, to a degree; bad use, naw; just another card to lose. My personal opinion, got way too long, sorry. Stay safe--
