WOTC - Should NRIC be kept confidential

I asked this question in the Wisdom of the Crowd:

Should the NRIC be kept confidential?

Here are the responses: (63 Votes)

51 % - The NRIC should be shown, but should not be retained by a third party.
25 % - The NRIC should be kept private and confidential
19 % - It is confusing to keep the NRIC private when it is required to identify a person.
5 % - It is a means of identifying a person and should be public information.
