WALD UNATTRACTIVE passport photos, once merely traditional, may become mandatory. The reason is that computers do not like smiles. A United Nations agency that sets standards for passports wants all countries to switch to a document that includes a "biometric feature," a digital representation of the bearer's face recorded on an embedded computer chip. In airports and at border crossings, a machine will read the chip to see if the information there matches the bearer's face. But the machine can be flummoxed by smiles, which introduce teeth, wrinkles, seams and other distortions. The State Department issued instructions that passport photos "should be neutral (non-smiling) with both eyes open, and mouth closed." In a grudging sop to the irrepressible, a "smile with closed jaw is allowed, but is not preferred." A State Department spokeswoman pointed to another page of the Web site where "neutral" had been changed to "natural." But it, too, said that the mouth should be closed. Canada and Britain have issued similar instructions. In the end, some critics say, the joke may be on the government, because the face recognition system may deal poorly with aging, and a passport is good for 10 years. -- ----------------- R. A.
