In other words, all the chip does is confirm what is printed in the passport. What it does not do is prove the holder is the person he or she claims to be—no more so than a traditional passport did. If the person has a reasonable likeness to the photograph—and therefore similar biometric details—a stolen e-passport could readily be accepted. Or if the passport is a fake and the chip cloned, it could just as easily pass muster. As always, it will come down to the experienced eye of the immigration official—whether it's a chipped passport or a traditional one.
