India (in)

Biometric passport: Yes

According to Wikipedia, citizens of India can/must have biometric passports [doesn't imply retaining biometric information].

National ID card: Not compulsory

According to wikipedia, Gambia and Iraq seem to have compulsory biometric databases for all citizens (This is only a parial list. For example: Pakistan isn't mentioned). In India it is not compulsory, and in Israel — it's considered to be at a "pilot" stage, so citizens can still refuse to submit their biometric data.
