Singapore National Registration Identity Card View

SingaporeNationalRegistrationIdentityCardView is a headless read-only display of Singapore's National Registration Identity Card Number / Foreign Identification Number (NRIC/FIN), Singapore's government-issued personal identifier. It renders as a <span> with an accessible label. It is the read-only companion to SingaporeNationalRegistrationIdentityCardInput.

Status: beta — implemented and unit-tested in all seven frameworks; not yet exercised in a composed flow.

Implementation Notes

• Renders as <span>
• Format: One letter (S or T for citizens/permanent residents; F or G for long-term foreign residents; M for newer FIN series), seven digits, and a trailing check letter. The check letter is computed by multiplying the seven digits by fixed weights (2,7,6,5,4,3,2), summing the products (adding 4 for a G/T prefix or 3 for an M prefix), taking the sum Modulus 11, and mapping (10 - remainder) through a lookup table to a letter.
• Provides accessible name via the label prop
• Companion to SingaporeNationalRegistrationIdentityCardInput

Props

• value: string (default: "") — the identifier to display
• label: string (required) — accessible label via aria-label
• ...restProps: any — additional HTML attributes spread onto the <span>

Usage

<SummaryList>
  <SummaryListItem term="National Registration Identity Card Number / Foreign Identification Number (NRIC/FIN)">
    <SingaporeNationalRegistrationIdentityCardView label="National Registration Identity Card Number / Foreign Identification Number (NRIC/FIN)" value={value} />
  </SummaryListItem>
</SummaryList>

ARIA

• aria-label={label} — provides the accessible name

When to Use

• Use to display a stored Singapore National Registration Identity Card Number / Foreign Identification Number (NRIC/FIN) read-only.
• Use in summary lists, patient records, audit logs, or detail views.
• Use when the identifier should not be editable in the current context.

When Not to Use

• Do not use for editing identifiers — use singapore-national-registration-identity-card-input instead.
• Do not use for general text display — use a <span> directly.
• Do not use for other countries' identifiers — use the corresponding country-specific view.

Headless

This headless component ships zero CSS. The consumer provides all styling targeting the .singapore-national-registration-identity-card-view class hook.

Testing

• Verify renders a <span> with the correct class
• Verify the value prop is rendered as text content
• Verify aria-label is set from the label prop
