Ask HN: How do I reverse engineer my country's Smart ID Card

I'm from Pakistan, and we recently had our National ID cards updated to the Smart National ID Card (SNIC).

Trouble is, despite have a chip like a smartcard, there is no documentation on the Smart Card, or the "Smart" functionality of the card.

I'm an Estonian E-Resident[1], and I can sign documents using my Estonian ID card's certificates, but nothing pops up when I plug my SNIC into the my +ID Smartcard Reader[2].

I'm a developer, and fairly competent at learning new things, but there's no straightforward guide on how to read the data on my ID card.

Could you provide any resources I can look up to find out what this piece of plastic is capable of?
