Abstract: A device for managing mold operation for production of molded objects of building material, such as for example concrete, discourages tampering of data collected pertinent to use of a particular mold over time. Various relevant parameters of the manufacturing process are stored in a transponder during active use thereof on a building material machine, the transponder being non-detachably connected to the production mold. The transponder is fixed to the mold in a manner inhibiting tampering with data stored therein and shielding same from mechanically induced damage. The above arrangement of the device permits subsequent retrieval and utilization of the accumulated stored data with write/read equipment available only to authorized personnel.
