Problems solved by technology

[0003] Memory card, also known as secure digital card or SD card, is a memory device based on semiconductor storage technology. It not only has high memory capacity, fast data transmission, small size, but also is easy to carry and high security. It is widely used in portable electronic devices. In the prior art, a smart SD card (Smart SD card) is a combination of smart card chip and storage function. Mobile communication devices can be connected by SWP (Single Wire Protocol, single wire) Protocol), CLF (Contactless Frontend, non-contact communication module) and antenna to communicate with the smart SD card. However, to use this kind of smart SD card, the mobile communication device must have CLF and antenna, and it cannot pass external devices, such as: 7816-3IC reading device to realize contact transactions, and it is impossible to complete contactless transactions when the power of mobile communication devices is insufficient
[0004] Another kind of smart SD card is to place the smart card chip, storage function, antenna and SD controller on one SD card, which can reduce the requirements for mobile communication devices, but for metal shell mobile phones or other mobile phone structures When the non-contact signal is shielded, the non-contact transaction cannot be completed. In addition, such a design cannot realize the contact transaction through external equipment, such as using a 7816-3IC reading device
[0005] Moreover, the smart SD card in the prior art is different from the standard financial smart card in shape, so it cannot be applied to the existing standard financial smart card reading device. However, the non-contact performance of smart SD card products is still much worse than that of standard dual-interface smart cards that are suitable for contact and non-contact communication.

Abstract

The present invention relates to a memory card with a smart chip which includes a substrate, a smart chip installed on the substrate, a memory card controller and a memory card standard connection terminal group; the substrate is provided with a smart chip connection terminal group which conforms to a smart chip communication protocol, the memory card standard connection terminal group and the smart chip connection terminal group are respectively exposed on the memory card; through the technical solution, the current contact and non-contact reading devices are plugged via adaptors, moreover, after transferring personalization data to the adaptor , the contact and non-contact reading devices from the public transportation card-issuing system directly transfers to the memory card with the smart chip via original pick-up heads and do not need the conversions of other protocols to realize the large-scale card production based on the current distributing equipment.

Description

technical field [0001] The invention relates to a memory card, in particular to a memory card with an intelligent chip. Background technique [0002] In the existing technology, with the development of mobile communication technology, such as: 3G (3rd-Generation), WiMAX (Worldwide Interoperability for Microwave Access), LTE (Long Term Evolution) and other mobile communication technology development, and with the wireless communication technology For example, the technology of Near Field Communication (NFC) has developed a mobile payment mechanism (MobilePayment), which allows users to pay conveniently to achieve the purpose of mobile consumption. Therefore, various mobile payment mechanisms have been realized. Advanced mobile payment devices and payment media have therefore been continuously developed. [0003] Memory card, also known as secure digital card or SD card, is a memory device based on semiconductor storage technology. It not only has high memory capacity, fast d...
