This is not the first time foreign nationals or migrants have been used as guinea pigs to test a law or technology. Examples include the Asylum Registration Cards (ARC), which is a similar card that asylum seekers have been required to carry since 2002. Once migrants have been used as a 'road test' for the widely opposed ID scheme, the government will start on the rest of us. From 2010 on, the government predicts that one million cards will be handed out every year.
