Magyarorszag Taj Szam Input

MagyarorszagTajSzamInput is a headless input for entering Hungary's Társadalombiztosítási Azonosító Jel (TAJ), Hungary's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to MagyarorszagTajSzamView.

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: Nine digits, displayed as SSS SSS SSK. The first eight digits are a simple issued-in-order serial number; the ninth is a check digit computed by multiplying the first eight digits by alternating weights 3 and 7, summing the products, and taking the result Modulus 10 — an algorithm unique to Hungary, distinct from Luhn.
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
• Companion to MagyarorszagTajSzamView

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="Társadalombiztosítási Azonosító Jel (TAJ)" required>
  <MagyarorszagTajSzamInput label="Társadalombiztosítási Azonosító Jel (TAJ)" value={value} required />

When to Use

• Use in forms collecting Hungary's Társadalombiztosítási Azonosító Jel (TAJ).
• 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 magyarorszag-taj-szam-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 .magyarorszag-taj-szam-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
