Embodiment Construction

[0026] The implementation of this case will be described below in conjunction with the accompanying drawings.

[0027] This case provides a chip card that can be connected together without changing the hardware equipment of the original communication device and the external memory card reader, so that the data of the external memory card can pass through the chip card through the chip card The communication device for transmission is not only more convenient to use and does not need to be limited to a wired network environment, but also more secure in the transmission of confidential data, which can avoid the risk of confidential information being leaked. The implementation method will be described in detail below. Although the present embodiment will be described with the GSM communication system, those skilled in the art should know that it is not limited thereto, and the present invention can also be applied to communication systems such as GPRS, 3G, CDMA, and WCDMA.

Abstract

The invention discloses a chip card which is arranged at a communication device to be used as a data transmission medium between an external storage card and a remote authentication unit. The chip card comprises a processor, an encryption unit, a connection interface and a connection unit, wherein the processor reads the data of the external storage card through a reading device; the encryption unit is used for encrypting the read data; the connection interface is used for transmitting the encrypted data to the communication device to enable the communication device to transmit the encrypted data to the remote authentication unit; and the connection unit is electrically connected between the processor and the reading device and used for transmitting the data of the external storage card to the processor from the reading device. By connecting a mobile phone with a card reader of the external storage card, under the condition that any hardware of the original mobile phone and the card reader of the external storage card are not improved, the chip card achieves a safe and convenient transmission behavior and further saves expenses of relative hardware.

Description

technical field [0001] This case relates to a chip card, especially a chip card that can provide a mobile communication device with the function of reading an external memory card. Background technique [0002] With the increasing development of social finance, the number of credit transactions has sprung up, and in various credit transactions, due to the convenience of using credit cards for consumption, it occupies an important position for ordinary consumers. It has become the main transaction mode in the daily purchase of goods. In the conventional credit card payment method, after the merchant enters consumption data such as the amount of consumption in the credit card machine, the consumer's credit card is inserted into a credit card machine for swiping to read the credit card data, and the credit card machine prints the credit card again. Transaction data such as information, consumption amount, card reader number (ie store number) and card reader time are transmitte...
