Abstract
Methods and devices are provided for installing and hiding applets onto smart cards devices. In a first step, a request for installing an instance of a first applet is received at the card device from an off-card entity. The request includes a first applet identifier. An applet instance is then installed with the first applet identifier in a registry of the card device's operating system. In a further step, a request for hiding the instance of the first applet identified by the first applet identifier is received at the card de-vice from the off-card entity. After receiving the hiding request, the smart card operating system finds the applet instance with the give applet identifier and hides it.
