A skating blade with a cross-section of three different portions. The method includes distributing a feature testing tool, computing feature builds, and data sets to client computing systems. The virtual contact card, when updated by the user, may be automatically sent by the service provider to the same recipients that previously received a pre-updated version. A relative adder adds the immediate value and the instruction pointer value to arrive at the target recovery address. The measuring standards are positioned with respect to each other such that at least one code track of a first measuring standard and at least one code track of a second measuring standard at least partially overlap and the position information of at least one of the code tracks is scannable by the scanning unit in the region of overlap. In embodiments, this method further comprises, if a set of items of the document possesses associated values, a step of coding said values associated with said set of items of the document.
