What are the structure, dimensions, thickness, and weight of a standard smart card?

The smart card structure mentioned here refers to the finished product structure, meaning what is made up of a smart card. The smart card mainly consists of a top layer of 0.04MM film, plus 0.17mm PVC material, 0.2MM PVC material, 0.3MM PVC material, 0.17MM PVC material, and finally a 0.04MM thick film. A small smart card Yet few people know that it is made up of so many layers of material.

The standard smart card measures 85.5*54*0.84MM, with 85.5 referring to the card's length. 54 refers to the width of the smart card, and 0.84 is the thickness of the smart card. Their unified unit is millimeters (MM).

The standard smart card weighs 6~8g. If a 0.84MM thick smart card can only hold 200 cards, each box of 200 cards multiplied by the weight of 8g per card, so the thickness of a smart card is: 200*8=1600g, which means one box is 1.6 kg. One box can hold 25 smart cards, which means each box can hold 5,000 cards. 5,000 cards multiplied by 8g = 40,000g, which is 40 kilograms.
