    \"MRZ-ID-CARD\"<\/p>

    Los documentos m\u00e1s peque\u00f1os, como los carn\u00e9s de identidad y los pasaportes, suelen tener el tama\u00f1o TD1, que es de 85,6 * 54,0 mm (3,37 * 2,13 pulg.), el mismo tama\u00f1o que las tarjetas de cr\u00e9dito. Los datos de la zona legible por m\u00e1quina de una tarjeta de tama\u00f1o TD1 constan de tres filas de 30 caracteres cada una. Los \u00fanicos caracteres utilizados son A-Z, 0-9 y el car\u00e1cter de relleno <. <\/p>

    Algunos documentos de viaje oficiales tienen el tama\u00f1o TD2, m\u00e1s grande, de 105,0 * 74,0 (4,13 * 2,91 pulg.). Tienen un dise\u00f1o de la MRZ con dos filas de 36 caracteres cada una, similar al formato TD3, pero con 31 caracteres para el nombre, 7 para el n\u00famero personal y un d\u00edgito de control menos. Sin embargo, algunos documentos de viaje oficiales tienen formato de libreta con una p\u00e1gina de identidad TD3. <\/p>
