Smart card has been a new trend as practical and secure authentication solution in online transactions such as e-payment, net-banking, e-money, and other online services. The increasing of smart card-based applications demands higher supply of smart card readers as well. Many types of smart card readers in the market have been existed. However, their feature and software are mostly closed and can not be modified to satisfy the application developer's requirements to optimize the performance and security of the applications. Therefore, a self-designed smart card reader is needed to offer flexibility and ability to be costumized in order to satisfy application developer's needs. In this research, a smart card reader is designed based on 32-bit microcontroller STM32F407VG which is implemented on STM32F4 Discovery Kit. The proposed smart card reader is evaluated by accessing information resides on the JCOP31 smart card which has been pre-installed by applet with certain APDU. Evaluation results show that the proposed smart card reader is able to access smart card properly, having good portability on different platform machines and having good performance as indicated by the CWT and CBT which are faster than the recommended ones. Intisari-Smart card telah menjadi tren baru sebagai solusi autentikasi yang praktis dan aman pada berbagai transaksi online seperti pembayaran online (e-payment), transaksi perbankan online (net-banking), transaksi berbasis uang elektronik (e-money), maupun layanan online lainnya. Meningkatnya jumlah aplikasi berbasis smart card berakibat pada meningkatnya pula kebutuhan mesin pembaca smart card atau sering disebut dengan smart card reader. Ada banyak tipe dan merk smart card reader yang tersedia di pasaran, tetapi umumnya fitur dan perangkat lunaknya bersifat tertutup sehingga tidak dapat dimodifikasi apabila pengembang aplikasi memerlukan kustomisasi untuk mengoptimalkan kinerja dan keamanan aplikasinya. Oleh karena itu, diperlukan sebuah perangkat smart card reader yang fleksibel dan dapat dikustomisasi untuk memenuhi kebutuhan pengembang aplikasi. Pada makalah ini, sebuah smart card reader dirancang menggunakan rangkaian minimalis berbasis mikrokontroler 32-bit STM32F407VG. Rancangan smartcard reader diimplementasikan pada STM32F4 Discovery Kit. Pengujian dilakukan dengan membaca informasi pada smart card bertipe JCOP31 yang di dalamnya sudah terinstal applet dengan perintah APDU tertentu. Perintah untuk membaca dan menampilkan hasil pembacaan smart card dikendalikan oleh komputer melalui aplikasi GUI. Hasil evaluasi dan pengujian menunjukkan bahwa rancangan smart card reader mampu bekerja mengakses smart card dengan baik, memiliki portabilitas pada beberapa platform mesin yang berbeda serta memiliki kehandalan yang baik yang ditunjukkan oleh waktu CWT dan BWT yang singkat dan memenuhi standard spesifikasi yang direkomendasikan.

With the level of complexity of the products was higher and higher, as a technology which can accelerate the development process, process modeling has become the focus of the domestic and international scholars. This paper studies the association relationship between the components’ structure of product design, and introduces the hierarchical principle of the feedback mechanisms, and constructs a new process modeling method based on the global design method, which improve the ability of description of the process model and the flexibility of the new product’s design. Then this method is applied to the car spraying production line.
