Identification card

Abstract

An identification card includes a ceramic substrate with opposite surfaces, and an accommodating part. A marking joint part is arranged in the accommodating part, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate. The marking joint part includes a bearing layer and a marking part arranged on the bearing layer. The bearing layer and the marking part are of an integrated structure. The ceramic substrate is provided with an accommodating part for setting a marking joint part to ensure the flatness of the identification card, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate.
