Field notes
The page distinguishes five document layouts by line count and character width, including credit-card-sized TD1 identity documents and 44-character-per-line TD3 passports. It presents decoded fields such as nationality, document number, birth date, and expiry date, alongside check-digit verification. The site states that processing happens locally in the browser, which limits the exposure of pasted document data according to its own description.
