1. An apparatus comprising:
- a memory element configured to store information; and
a switching element coupled to the memory element;
wherein the switching element is configured to be switched from a first state to a second state in response to an input signal from a capacitive touch screen external to the apparatus and wherein when the switching element is in the second state the memory element is configured to provide at least part of the information in the memory element to the capacitive touch screen external to the apparatus; and
wherein the memory element and the switching element are configured to enable an electrode to be connected to and disconnected from ground.
