A cordless, electro-optical reader (30) is compatibly docked with different docking stations having station contacts located at different locations. A rechargeable battery is mounted in a housing that extends along a longitudinal axis. Multiple housing contacts (40, 42, 44, 46,48) are located on the housing. Some housing contacts conduct electrical power to recharge the battery; other housing contacts conduct electrical signals to and from a controller. Each housing contact has one exposed contact portion facing in a first direction, e.g., axially along the longitudinal axis, to make electro-mechanical contact with station contacts located at one location of one docking station, and another exposed contact portion facing in a different second direction, e.g., transversely of the longitudinal axis, to make electro-mechanical contact with station contacts located at another location of another docking station. |
