Abstract:
1. A method of making a microcircuit card comprising a card body ( 11 ) and a module ( 22 ) comprising a support film ( 23 ) forming a printed circuit carrying a microcircuit ( 26 ) on one of its faces, the method comprising the steps of: providing the card body with a cavity having a bottom and a sidewall; surface treating at least an entirety of the bottom of the cavity to increase adherence of a predetermined resin to the bottom; depositing a required quantity of resin; positioning the module in the cavity so that the microcircuit is surrounded by the resin; and polymerizing the resin, the resin filling at least a part of the cavity so as to adhere to the bottom and surround the microcircuit, said surface treating being such that the adherence of the resin to the bottom is greater than adherence of the resin to the support film of the module, whereby the microcircuit is separated from the support film when a fraudulent attempt is made to remove the module from the card body.
