Problems solved by technology
At present, the telecommunications IC card with contactless payment function is mainly implemented on a large-capacity dual-interface chip, but this chip is only provided by a few chip suppliers, so the cost of the chip is bound to be greatly increased. At the same time, it increases the difficulty of code porting, increases R&D cost investment, and prolongs the R&D cycle, which is not conducive to responding to the rapidly developing market
[0004] The main technology used in the existing telecommunications IC card with contactless payment function is to implement related functions on a large-capacity dual-interface chip. The disadvantages of this technology mainly include: 1. The cost of the chip is greatly increased; 2. Difficulties in code transplantation; 3. Prolonging the R&D cycle is not conducive to the rapid response to the market; 4. Increased R&D cost investment

The invention discloses a non-contact payment telecom integrated circuit card and an implement method, and relates to the field of non-contact payment; cost increase caused by changing a chip is effectively reduced, and convenience is brought to code transplantation. The non-contact payment telecom integrated circuit card comprises: a contact chip, including a first input and output pin, a first reset pin, a first power supply pin, a first grounding pin, a first clock pin and a plurality of universal input and output pins, and a non-contact chip, including a second input and output pin, a second reset pin, a second power supply pin, a second grounding pin and a second clock pin, wherein the contact chip and non-contact chip share same grounding end and clock signal, the contact chip is connected with an external interface device to achieve telecom function and a menu relating to payment function, the non-contact chip is used for achieving non-contact payment function, the contact chip is connected with the non-contact chip by reusing the universal input and output pin so as to control the non-contact chip and transfer data with the same.
Description
technical field [0001] The invention relates to the field of non-contact payment, in particular to a method for implementing a non-contact payment telecommunication integrated circuit card core. Background technique [0002] With the development of integrated circuit technology, the scale, integration and complexity of the circuit are getting higher and higher, making IC card (Integrated Circuit Card, integrated circuit card) technology has made great progress. In order to adapt to the rapid development and promotion of IC card, the international The standardization organization has launched a protocol specifically for IC cards, namely the ISO7816 protocol. [0003] At present, the contact IC card technology has developed relatively maturely, while the non-contact IC card technology is developing vigorously. But at present, the most practical application of non-contact IC cards is the logical encryption card, which cannot meet the needs of many applications in terms of secu...
