Abstract

The invention discloses a smart card. The smart card comprises a first interface, a master control chip internally provided with business software for realizing the functions of a POS (Point-Of-Sale) terminal, and a radio frequency chip, wherein the radio frequency chip is used for building a wireless communication channel with a user RFID (Radio Frequency Identification) radio frequency card under the control of the master control chip; the master control chip is used for controlling the radio frequency chip to receive and transmit transaction data, and finishing the transaction process with the user RFID radio frequency card through the built-in business software which is used for realizing the functions of the POS terminal; and the smart card interchanges data with an external device via the first interface. The smart card further comprises an IC (Integrated Circuit) business chip. When the IC business chip is a mobile phone SIM (Subscriber Identity Module) card chip, after replacing the original SIM card of the mobile phone by the smart card disclosed by the invention, the mobile phone terminal can realize the functions of the POS terminal, so that the arrangement of the POS terminal is facilitated and the arrangement cost is reduced; and since the software for realizing the POS functions is set in the smart card, the software is convenient to upgrade.

Description

technical field [0001] The invention relates to the field of micropayment, in particular to a smart card and a POS terminal. Background technique [0002] The traditional micropayment system mainly consists of three parts: card, POS terminal, and background system. The communication method between the card and the POS terminal adopts the non-contact radio frequency communication method. The card is a non-contact smart card, held by the user, and the POS terminal runs business processing software, which is the direct interface between the user and the system for transactions. [0003] At present, the application of RFID-SIM cards in mobile phones in the field of small payment has been well developed. In order to better promote the application of RFID-SIM cards in micropayments, the configuration of corresponding facilities should also be improved simultaneously. However, the current situation is not the case, and the number of POS terminals used with RFID-SIM cards in the m...
