Due to the demand for personalized printing that is not limited by size, various "strange" cards have emerged in countries around the world, which we call irregular cards.

Standard cards are internationally standardized card products with dimensions of 85.5mm × 54mm × 0.76mm. Nowadays, due to the demand for personalized printing that is not limited by size, various "strange" cards have emerged in countries around the world, which we call irregular cards. Geometric cards such as rectangles, squares, triangles, ellipses, and circles are referred to as "non-standard cards"; Some special shaped cards in the shape of animals or dolls are called "quasi alien cards". Relatively speaking, the production process of "quasi irregular shaped cards" is more difficult than geometric shapes.

The common shaped cards have two main uses. On the one hand, they are used for chest cards, and on the other hand, they are mainly used for access cards. They can be made into dozens of shapes, such as keychain cards and coin cards, just like the remote control on a car, which is both modern and beautiful.

Nowadays, there are more and more printed materials made of PVC used in various aspects, such as exhibition tickets, exhibition display boards, and advertising boards used in shopping malls.

A non-standard card does not refer to a certain type of card. Simply put, irregularly shaped cards can be called alien cards. Heterogeneous cards can encapsulate various chips, which means they can have multiple different functions.
