Dual-chip mobile payment intelligent card and control method thereof

Abstract

The invention provides a method for controlling a dual-chip mobile payment intelligent card, which comprises the following steps: a dual-interface control chip receiving a command and transmitting to a soft mask chip of the intelligent card; the soft mask chip of the intelligent card receiving the command transmitted by the dual-interface control chip, and interrupting the command currently processed, starting to process newly-received command; and the soft mask chip of the intelligent card calling corresponding function module to process the received command. The method for controlling the dual-chip mobile payment intelligent card provided by the invention can be fully compatible with the existing 13.56MHz non-contact application environment with widest application and can enlarge an application space through the integrated high-capacity intelligent card soft mask chip, and the intelligent card chip in a soft mask manner can better adapt to the demand of continuous changes of communication application and shorten development time.

Description

【Technical field】 [0001] The invention relates to a mobile payment smart card and a control method thereof, in particular to a dual-chip mobile payment smart card and a control method thereof. 【Background technique】 [0002] Mobile payment is usually also called mobile payment, which allows users to make on-site payment for the goods or services they consume through the terminal equipment they carry, such as swiping a card to buy tickets when taking a bus or subway, swiping a card to buy movie tickets at a movie theater, and buying a movie ticket at a supermarket or The hotel pays by credit card. [0003] The realization of mobile payment on the terminal mainly depends on two methods. The first way is to develop applications directly on the hardware platform provided by the mobile phone. For example, the NFC (Near Field Communication, short-distance wireless communication) mobile phone of NTT DoCoMo in Japan, the radio frequency chip used to realize wireless communication a...

Problems solved by technology

[0011] (1) The interface standard of the SWP solution conforms to international standards, and can be effectively compatible with existing 13.56MHz contactless applications. However, there are still very few terminals supporting SWP, and there are no commercial terminals launched in large quantities. Users replace terminals for payment functions The requirements will be the biggest obstacle to this technical solution

[0012](2) 13.56MHz single-chip dual-interface smart card chip currently generally has a small user space, and in the field of communication applications, it is generally necessary to support more than 64K telecom value-added application space. This makes it difficult for the single-chip dual-interface smart card to meet the application requirements of the current mobile payment card. Some cases basically focus on the display of the payment function, and basically abandon the rich communication applications; in addition, the existing single-chip dual-interface smart card chips basically need to be masked Development, its development cycle is relatively long, it is difficult to adapt to the rapidly changing user needs in mobile communication applications

Radio Frequency (RF) smart card uses 2.4G radio frequency chip and antenna with small size and good signal penetration. The lack of international standard support requires a lot of transformation work on the existing payment environment. On the one hand, operators need to bear huge equipment transformation costs. On the other hand, due to the uncertain risks brought by the lack of standard support, this technology is also very difficult It is difficult to obtain strong support from some partners
