Bharat Aadhaar Input

BharatAadhaarInput is a headless input for entering India's Aadhaar (आधार), India's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to BharatAadhaarView.

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

Implementation Notes

• Renders as <input type="text">
• Format: Twelve digits, the first of which is never 0 or 1. The twelfth digit is a check digit computed with the Verhoeff algorithm, a checksum that detects every single-digit error and every adjacent-digit transposition. Issued by the Unique Identification Authority of India (UIDAI).
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
• Companion to BharatAadhaarView

Props

• label: string (required) — accessible label via aria-label
• value: string (default: "") — bindable input value
• required: boolean (default: false) — form validation
• disabled: boolean (default: false) — disabled state
• ...restProps: any — additional HTML attributes spread onto the <input>

Usage

<Field label="Aadhaar (आधार)" required>
  <BharatAadhaarInput label="Aadhaar (आधार)" value={value} required />
  <Hint>Twelve digits, the first of which is never 0 or 1. The twelfth digit is a check digit computed with the Verhoeff algorithm, a checksum that detects every single-digit error and every adjacent-digit transposition. Issued by the Unique Identification Authority of India (UIDAI).</Hint>
  <ErrorMessage>Please enter a valid Aadhaar</ErrorMessage>
</Field>

ARIA

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

When to Use

• Use in forms collecting India's Aadhaar (आधार).
• Use in administrative or national-id workflows where the identifier is required.

When Not to Use

• Do not use for displaying read-only identifiers — use bharat-aadhaar-view instead.
• Do not use for general text input — use text-input instead.
• Do not use for other countries' identifiers — use the corresponding country-specific input.

Headless

This headless component ships zero CSS. The consumer provides all styling targeting the .bharat-aadhaar-input class hook.

Testing

• Verify renders an <input> with the correct class and type="text"
• Verify aria-label is set from the label prop
• Verify autocomplete="off"
• Verify value binding works
