The present invention provides a coil pad (22) for wireless power transfer having a back plane and a front plane radiating an electromagnetic field during wireless power transfer, wherein the coil pad (22) has a circumference (32) encompassing an imaginary positioning contour (34, 48, 52, 56, 60, 64) reflecting positioning options for at least one point-to-point communication element to be embedded into the front plane of the coil pad (22), the imaginary positioning contour (34, 48, 52, 56, 60, 64) has rotational symmetry with respect to a first axis of symmetry 82 and a first axis of symmetry 84 orthogonal to the first axis of symmetry 82, the first axis of symmetry 82 and the first axis of symmetry 84 intersecting at an origin and defining an imaginary coordinate system for the front plane of the coil pad, and the coil pad (22) comprises a first point-to-point communication element (26) embedded into the front plane of the coil pad at a first position being an intersection of the imaginary positioning contour (34, 48, 52, 56, 60, 64) and an imaginary positioning hand (44) extending from the origin of the imaginary coordinate system along a first direction defined by a first angle of rotation π + α, 0 ≤ α ≤ π/2 in clockwise direction relative to the first axis of symmetry 82.
