Abstract:

To meet the smart cards’application requirements in the banking, insurance, medical management systems, a smart card reader system is designed based on ARM. The chip STM32F103RBT6 with ARM CortexM3 and the near field communication transceiver STRFNFCA are used in the hardware design. In the process of software design,it gives initialization operations and application layer data transactions,LCD display between contactless/contact IC card and reader,implements smart card’s financial transactions including credit for load, debit for purchase and getting balance transactions, and integrates Crypto 1 encryption algorithm into reader so as to be compatible with Mifare cards.Experimental results indicate that the system has stable performance, low power consumption,strong practicability and high reliability.
