Abstract

A standard size smart card has a flat support with a slot in the support to define the boundary of a minicard attached to the support by lugs. Each lug has two types of grooves opposite each other so they provide sufficient resistance to bending and flexing. One of the grooves is configured so it starts to crack when the minicard is purposely subject to pressure.
