When cutting and pasting materials in each process, smart cards are provided. Every worker is equipped with an access control work permit for attendance and food sales. Install a card reader with dual reading heads on each locomotive. In the production process, workers first insert their own work cards, then insert material cards on the work orders and start work. The system begins to collect data. After completing a work order, replace the material card of the next work order, and there is no need to keep the flying tail. The system automatically records when each worker does what work and how long it takes. On the production line, the number of subsequent work orders is automatically obtained by using a single reader. Employees can check the production records of the whole day through the self-service credit card terminal. You can visit the website of China Chuangyi.
