Progressive unplugging multi-cards body

A card body manufacturing method comprising the following steps:

• a first manufacturing step comprising manufacturing a first card body having a first shape with a first perimeter comprising a first plurality of sides, and a cavity for receiving an electronic module,
• a second manufacturing step comprising manufacturing:
• a second card body having a second shape with a second perimeter comprising a second plurality of sides, the first card body encompassing the second card body, and the first shape and the second shape being separated by a first boundary,
• a third card body having a third shape with a third perimeter comprising a third plurality of sides, the second card body encompassing the third card body, and the second shape and the third shape being separated by a second boundary,
• wherein none of the second plurality of sides of the second perimeter share a common side with any of the first plurality of sides of the first perimeter, and wherein none of the third plurality of sides of the third perimeter share a common side with any of the second plurality of sides of the second perimeter, and
• wherein the second manufacturing step comprises the further following steps:
• a first punching step consisting in punching a first number of apertures and a second number of apertures, a cumulated length of the first number of apertures being greater than a cumulated length of the second number of apertures, and
• a second punching step consisting in punching a first number of notches and a second number of notches, a cumulated length of the first number of notches being lesser than a cumulated length of the second number of notches.

A card body comprising:

• a first card body having a first shape with a first perimeter comprising a plurality of sides,
• a second card body having a second shape with a second perimeter comprising a plurality of sides, the first card body encompassing the second card body, the first card body coupled to the second card body, and
• a third card body having a third shape with a third perimeter comprising a plurality of sides, the second card body encompassing the third card body, the second card body coupled to the third card body, the third card body having a cavity for receiving an electronic module,
• wherein none of the plurality of sides of the second perimeter share a common side with any of the plurality of sides of the first perimeter, and wherein none of the plurality of sides of the third perimeter share a common side with any of the plurality of sides of the second perimeter.
