1. A data entry device intended to be affixed to a touch panel of a terminal, said touch panel being capacitive, said data entry device comprising:
a substantially parallelepipedal plate comprising a lower face, substantially planar, for affixing the device to the touch panel, and an upper face comprising a matrix of entry areas forming a keyboard, the entry areas being configured to allow a detection of a user's finger by the touch panel when the device is affixed to the touch panel;
at least two contact pads independent of each other, that is to say electrically insulated in relation to each other, electrically conductive and arranged on the lower face;
wherein said contact pads are each electrically connected to additional means for evacuating, towards the outside of the touch panel, the electric charges concentrated at the contact pads when said data entry device is affixed and held on said touch panel,
wherein said additional evacuation means evacuate, towards the user's body, the electric charges concentrated at the contact pads when said data entry device is affixed and held, via the additional evacuation means, by the user on said touch panel of a terminal,
wherein said additional means for evacuating the electric charges comprise at least one surface for holding, by a user's finger, the entry device on the touch panel, said at least one holding surface being electrically connected to each of said at least two contact pads, respectively via a conductive tab, and
wherein said additional means for evacuating the electric charges comprise a first surface and a second surface for holding the data entry device on the touch panel, said first and second holding surfaces respectively being in the form of a cavity shaped according to a print of a left thumbprint and according to a print of a right thumbprint.
