On the subject of biometrics and passports, this was posted earlier on this forum by
@cujenn81 (snipped for focus):

all passports issued after 2007 contain biometric data chips and the biometrics are derived from the photo you submit. That’s why they have such strict guidelines — the height of the head should measure between this many and that many inches, eye height should be this many inches from the bottom of the photo, full head from the top of the hair to the shoulders, head must be front facing with open eyes, closed mouth, neutral expression, no eyeglasses, no hat or head coverings unless it’s worn for religious purposes everyday, no shadow on face or background, must have plain white/off-white background, normal lighting, and on and on and on.
If your passport has that little square symbol (that kinda looks like a flag) on the front of it, it’s a biometric passport. That’s true for all countries, btw. The symbol is the same.

Below is my own post on this forum when earlier we were discussing biometrics and passports - - (BBM) --
I have dual citizenship, and one of my passports that was issued in 2015 (not the U.S.) has a page that says the following:
"This passport contains a contactless integrated circuit, which is an electronic device. In addition to the care and respect afforded a passport, please treat this document as you would any other portable electronic device and take precautions that it doesn't become wet, folded or damaged. Abuse may adversely affect the operation of the integrated electronic circuit and reduce its usefulness to the bearer and to border inspection personnel."
Once when we got off the plane on a trip overseas and were going through customs at the airport, the border inspection officer asked my husband to tilt his head slightly in a different direction, so we knew that he was paying attention to some digital information at that point, while he held my husband's passport in his hand.
