A method, device, and system are disclosed. A floating point value is defined by a sign, an exponent and a mantissa. In a first embodiment, the stiffness of the stylet is adjustable. The object information is then transferred to one or more database server computers, where the object information can be compared to object information from other computers to determine whether the object is potentially identical to another object on one of the other computers. In order to ensure contacting with different conductors, the flat part is substantially coated with a metal and the inlay is partially coated with the metal.
