    Patent number: 8441340
    Abstract: A contactless tag reader device comprises upper and lower electrodes which together define a tag location zone between them in which multiple tags can be placed. The lower electrode and the upper electrode are offset from each other such that they substantially do not overlap. This structure is used to sandwich tags vertically between two horizontally (laterally) offset reader electrodes. This enables power coupling and data transfer using capacitive coupling.
