RFID card reading system. HEMAK s.r.o. provides a comprehensive system for operating vehicle scales, including self-service systems and number plate reading systems. Automatic systems enable more efficient and faster weighing with the storage of number plates in a database and photographs of weighted material. This removes the erroneous entry to the database. The system can be supplemented with car position sensors on the weighing bridge, traffic lights and ramps. Another option is RFID card readers with vehicle, cargo data, etc. There is also the option of weighing using remote control, which directly selects the number plate and material for the vehicle driver. The above systems can also be installed on already existing road bridge scales.
