Standard: ISO7816 defines the distance from the midpoint of the IC card chip to the edge of the card: 15.6MM, the distance to the upper edge: 23.89MM (8-PIN) 22.62MM (6-PIN), width: 85.72-85.47, height 54.03-53.92MM, thickness 0.84MM.

     IC card production process can be made according to the needs of the customer to produce the size or size of the card, for general contact ic cards are required to use the standard size card (convenient, accurate reading information). For contactless ic cards: the shape and size of the card can be designed in any way you like, because contactless ic cards are radio frequency cards and can be read by induction only, but they are a little more expensive than normal cards.
