1. A checking apparatus, comprising:
- a data transmitter forming one of a plurality of such transmitters disposed at fixed locations to be checked, each of said data transmitters having an elongated track magnetically encoded with data in a magnetically activatable form specific to the respective location and arrayed along the respective track;
a portable data-acquisition device formed with a head shiftable along the tracks of said data transmitters and including;
a magnetic-field generator in said head for magnetically activating the magnetic coding arrayed along each track upon shifting of said head therealong in a given direction,a code detector in said head behind said magnetic-field generator with respect to said direction for detecting the respective code, anda battery-powered electronic storage connected to said code detector for storing electrical signals represented by the code detected by said code detector; and
a data-evaluating device operatively couplable with said portable data-acquisition device for transfer of data represented by the electrical signals stored in said storage for evaluating said data.
