Sir: Your report about identity cards (3 February) is illustrated with a sample card, which shows a young woman smiling happily. Presumably this is to encourage us all to feel that identity cards are something to be pleased about. Such a cheerful expression is not acceptable for a passport photograph and is unlikely to be useable for an identity card. My identity card portrait, if I ever have one, will carry no such sunny expression, I assure you.
