Hong Kong smart ID card: security features, benefits and photo rules in 2026

The Hong Kong smart identity card is a credit-card-size polycarbonate card with an embedded chip that stores your personal data and thumbprint templates. The Hong Kong Immigration Department's "Identity Cards" Frequently Asked Questions page sets out the card's security design, the clearance and self-service benefits that come from the chip, and the photo situations that will be rejected. Anyone relocating to Hong Kong will use this card for immigration clearance, for updating a condition of stay, and as the base credential for electronic government services.

What is a Hong Kong smart identity card?

Hong Kong has issued identity cards in smart card form since 2003. A new smart identity card replaced the old one from 26 November 2018, under the Next Generation Smart Identity Card System.

The card is credit-card size, made from polycarbonate, and embedded with an integrated circuit, or chip, that stores and processes data. The polycarbonate body is described as giving strong resistance to environmental influences and to mechanical, chemical and thermal stress.

How secure is the card, and what protects the chip data?

The department publishes a separate leaflet, "Security features of New Smart Identity Card (with date of issue starting from 26 November 2018)", for the anti-forgery features. The FAQ itself describes the core protection: data are engraved into different layers of the card and stored in the chip, which helps prevent a lost or stolen card from being altered or used by other people.

Physical care matters as much as the chip design. The department's protection tips are:

Keep the card in an appropriate protective holder
Do not bend the card or test it with a magnet
Do not place the card together with keys or coins
Do not try to remove the chip from the card

A protective holder is supplied when the card is issued, but it will not be replaced if damaged or lost. A replacement holder should be made of ethylene vinyl acetate copolymer (EVA) with no plasticiser, and should measure not less than 93mm in length and not less than 61mm in width.

What does the chip actually let you do?

The chip is what turns the card from an ID document into a working credential. The department lists four benefits:

High security, because data are engraved into different layers and held in the chip
Greater convenience, since the card may be used in various non-immigration applications
Quality service, with the card described as the foundation of electronic government service delivery
More travel convenience, because thumbprint templates stored in the chip let holders use the e-channels of the Automated Passenger Clearance System and the Automated Vehicle Clearance System

For new arrivals, the third function of the card reader is the one worth knowing early. Using smart identity card readers installed at immigration self-service kiosks, you can view the personal data stored in the chip, view the content and change the PIN of a Hong Kong Post e-Cert if you have one, and update your condition of stay or limit of stay if you are a Hong Kong resident subject to a condition of stay. The department lists reader locations at Registration of Persons Offices and at immigration control points.

Which photo problems get an application rejected?

The photo must show your full frontal face with clear facial features. The department says a photo will not be accepted if, when you appear in it, you are (including but not limited to):

Seen with hair across eyes or eyebrows
Wearing head coverings, such as hats or a headband
Wearing ornaments, such as an earring, that obscure the ear or face
Seen with reflection on the frame or tinted lens
Wearing a frame across eyes or eyebrows
Wearing coloured contact lenses
Wearing overdone make-up
Not centred
Seen with exaggerated facial expressions
Seen with eyes tilted

The department also publishes a video, "Photo Taking Tips for Application of Hong Kong Identity Card".

Do you still need to replace an old smart ID card in 2026?

If you are still holding an old-form card, the replacement window has closed. Old-form smart identity cards issued before 26 November 2018 became invalid in phases in 2025: cards held by people born in or after 1970 became invalid on 12 May 2025, and cards held by people born in 1969 or before became invalid on 12 October 2025. Non-smart identity cards issued before 23 June 2003 were already declared invalid with effect from 30 November 2008.

The Territory-wide Identity Card Replacement Exercise has ended and all Smart Identity Card Replacement Centres closed with effect from 4 March 2023. Holders of the old form now book an appointment at a Registration of Persons Office. The appointment booking system currently offers a 96-working-day booking period, so plan around that if you are flying in specifically to replace a card.

If you are outside Hong Kong and have not replaced your card, apply within 30 days of your return. You must apply for a new smart identity card in person, though you may authorise another person to collect it on your behalf using Form ID678 if you cannot attend.

An invalid card will not be accepted for immigration clearance. You need a valid travel document to enter or leave Hong Kong, and if you present an invalid card on arrival it has to be surrendered and you will be ordered to apply for a new card within a specified period.

What does it cost, and what are the penalties for not replacing?

No fee is charged for an identity card issued to new arrivals or to people reaching the age of 11 or 18, and no fee was charged for a replacement made under the Territory-wide Identity Card Replacement Exercise. Fees are payable for replacing a card because of loss, damage, destruction, defacement or alteration of personal particulars; an approved amendment of registered particulars leads to a replacement card at a fee of HK$460.

On penalties, failing to apply for a new card within a specified call-up period without reasonable excuse is an offence under section 7B(3) of the Registration of Persons Ordinance, liable to a fine of $5,000 if prosecuted. Failing to comply with an order to replace a card within the specified period is an offence under regulation 19(4) of the Registration of Persons Regulations, liable to a fine of $25,000 and imprisonment for 2 years.

Does time away from Hong Kong affect your status?

Hong Kong permanent residents of Chinese nationality do not lose permanent resident status if their old-form card is invalidated and they have not returned to replace it; they can replace it within 30 days of return.

Permanent residents not of Chinese nationality face a different rule. If they have been absent from Hong Kong for a continuous period of not less than 36 months since they ceased to have ordinarily resided in Hong Kong, their right of abode in the Hong Kong Special Administrative Region may be affected. A person who loses the right of abode automatically acquires the right to land, which means entering Hong Kong freely to live, study or work without restriction.

Frequently Asked Questions

Can I use the smart identity card as a travel document?

No. Entry to and exit from Hong Kong requires a valid travel document, and an invalid identity card is not accepted for immigration clearance. If you only hold an acknowledgement of application for an identity card, you must still produce a valid travel document such as a passport or Hong Kong Re-entry Permit at control points.

Can I use the e-channels as soon as I have the card?

The thumbprint templates stored in the chip are what enable e-channel use. Holders can use the e-channels of the Automated Passenger Clearance System and the Automated Vehicle Clearance System.

Can I update my limit of stay at a self-service kiosk?

Yes, if you are a Hong Kong resident subject to a condition of stay. The smart identity card readers installed at immigration self-service kiosks let you update your condition of stay or limit of stay, view the personal data stored in the chip, and view or change the PIN of a Hong Kong Post e-Cert.

Can I wear glasses or a headband in the ID photo?

The published rules reject a frame across the eyes or eyebrows, reflection on the frame or tinted lens, and head coverings such as hats or headbands. A photo with hair across the eyes or eyebrows is also rejected, as is an off-centre face or an exaggerated expression.

What happens if I present an invalid old card when I arrive in Hong Kong?

The card has to be surrendered and you will be ordered to apply for a new identity card within a specified period. Holders of a replacement notice apply at any Registration of Persons Office within that period without a prior appointment, though the department warns that waiting times may be long.

Will I lose permanent residency if I stay outside Hong Kong and do not replace my card?

Permanent residents of Chinese nationality will not lose their status for that reason alone. Permanent residents not of Chinese nationality should note the 36-month rule: continuous absence of not less than 36 months after ceasing to ordinarily reside in Hong Kong may affect the right of abode, which is then replaced by the right to land.
