People born in or before 1927 must apply for a Smart ID Card from September 4 to November 11.

The Immigration Department said those who are away from Hong Kong during that period should apply within 30 days of returning.

If applicants' cards bear the "A" residential symbol or "***" symbol, or their cards were issued on or after January 1, 1999 and bear the "R" residential symbol, they need only bring their existing identity cards. Otherwise they should bring along travel documents showing their current residential status in addition to their cards.
