Abstract

The invention discloses a card data processing device with an audio standard interface and a processing method thereof. The device includes a device communication function module, a card data processing function module, a control unit, a power supply function module, and a device audio standard interface module. The audio standard interface module of the device is connected to the power supply function module through an internal bus, and the control unit is connected to the power supply function module, the card data processing function module, and the device communication function module through an internal bus. The invention adopts bluetooth / WIFI communication technology and card data processing function module, which can not only support the magnetic stripe, but also support the transaction of contact IC and non-contact IC. At the same time, it can be used with ordinary smart phones, and a special software can be run on the mobile phones. , Let the mobile phone become a POS machine that can accept magnetic stripe, contact chip, and contactless chip cards, which reduces the cost of the POS machine and is easy to carry and use.

Description

technical field [0001] The invention relates to audio connection, bluetooth / WIFI communication and card data processing module communication technology conforming to ISO7816 standard, ISO14443 standard and ISO7811 standard, especially a card data processing device with audio standard interface and its processing method. Background technique [0002] As a bank card processing device, the POS terminal is placed in the merchant to accept the cardholder's bank card and complete the card payment transaction. With the popularity of smart phones, a kind of analog POS terminal is driven by the advancement of information technology, and it is an evolutionary trend towards digitalization, low cost, high information processing capacity, high service scalability, and better user experience. "Mobile card reader" The product is a major innovation to the traditional POS terminal. [0003] Square, an American mobile payment operator, was the first company to launch "mobile phone card reade...
