From the Guardian Nigeria, part of an interview with the Lagos immigration boss
What are the most important features of the e-passport, and how can it be preserved?
The public should not believe that once 'Visa Refused' is put at one corner of the passport, the international document is useless. The passport is as good as the one coming out of the press. What we are saying is this: 'this document is very sensitive, keep it the way you keep your birth certificate.'
If you can keep your birth and professional certificates sacrosanct, away from cockroaches and water, why can't you keep your passport safely; if you can keep your holy books, the Bible and the Koran, from damage, you can as well keep our national symbol neat, not in a nylon bag.
Women keep it in their handbags containing cosmetics. You cannot do that! If you have an e-passport, and you have your degree certificate, you can keep them together. If you respect your degree certificate, I don't know why you cannot keep this one.
What is the greatest danger to this document?
The obvious danger one can inflict on it is staple pin; it is not supposed to be stapled to any other document; you do not apply pin on it because of the sensitivity and the chips in-built and already activated for verifications by other missions and agencies of other countries that are ICAO-compliant.
This passport is such that any other country that is under ICAO must have the software to read the passport. So, what you see physically is not what is embedded in it; everything about you is in it. If you present it somewhere else, within 30 seconds, the person is looking at the total you - your fingerprints, your eyelids and everything.
