I am old enough, only just, to have had identity card from the tail-end of WWII. I was also brought up watching all those prisoner of war filims where documents were always forged using cut-out potatoes to stamp out official seals and dye washed out of blankets for ink. My card looked as if it had been made in this way. Bigest problem with ID cards could be that if the information that is collated when the card is first issued is wrong or altered in some way, this wrong/altered information could well be regarded as being more correct than reality. So if your date of birth is out by ten years your pension and retirement dates could be a long time coming and I hate to think what could happen if your card was stamped for the wrong sex!!!!. cheers.
