The US authorities do take fingerprints on entry. But they have nothing to compare them with.
I have contradicting info: the US requires biometric passport on entry, that with significant biometric data.
We were talking about our UK passports not having biometric data contained within them. The US and UK are different countries.
ofc, but if you want to go to the US from UK, you must have a UK biometric passport with sufficient biometric data in the chip to satisfy the US customs.
