Abstract
The invention discloses an identification card and a preparation method for the identification card. The identification card comprises: a ceramic substrate, including a main body and an anti-grain film. The main component of the main body is zirconia powder. The textured film is arranged on each surface, and the ceramic substrate is provided with an accommodating groove located on at least one side surface of the main body and passing through the anti-grained film on the surface. The accommodating groove has a bottom surface and an opening opposite to the bottom surface; information identification The part is arranged in the accommodating groove. The information identification part includes a chip part and an information marking part. The orthographic projections of the chip part and the information marking part on the ceramic substrate do not overlap. The chip part has a lower surface and an upper surface opposite to each other. The lower surface Facing the bottom surface of the accommodating groove for accommodating the chip part, the upper surface does not protrude from the opening of the accommodating groove for accommodating the chip part. The ceramic matrix is formed of zirconia powder, with high hardness, high density and compact structure, which can further enhance the anti-bending and anti-wear performance of the identification card and improve the service life of the identification card.
Description
technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to an identification card and a method for preparing the identification card. Background technique [0002] An identification card is a medium used to identify an individual and store individual information. Various identification cards, such as work permits, ID cards, various financial transaction cards, membership cards, etc., have been widely used in people's lives. People have developed various anti-counterfeiting functions and / or decorations providing special visual effects on various identification cards, for example, various financial cards. The identification cards in the prior art are easily deformed and have low structural strength. [0003] Therefore, there is an urgent need for a new identification card and a preparation method for the identification card. Contents of the invention [0004] The embodiments of the present invention provide an i...
