I am so behind the times. Just received our new passports and it has been a long time since renewal. Our daughter did get a new passport 2 years ago for her job in Japan. However, our passports, unlike Kait's, now have computer chips inside. Apparently, all we have to do is look for the symbol at immigration stations at entry points and wave our passports at a chip symbol sign and we are in (or out) like flint.
Technology can be pretty cool.
Aging is another story but it beats the alternative.
