Why do supporters believe a national ID card would not violate privacy rights?
Supporters say that so much personal information is already gathered by private industry, there would be not much greater threat to privacy rights than exists now. We already require presentation of driver’s licenses to cash checks, get a post office box, board an airplane, buy alcohol, register to vote in some states, enroll in college and drive. Plus, the trade off for increased security is worth it. Also, some advocates have urged that the system be voluntary, at least for American citizens. However, those who opt not to have the card would be subject to greater inspection at places such as airports.
