Abstract
The utility model relates to a portable card reader. The portable card reader comprises a high-performance microprocessor and an ISO7816 standard clamping head. The high-performance microprocessor is connected with the ISO7816 standard clamping head, and reads the data of the ISO7816 standard clamping head. The high-performance microprocessor realizes communication with an external host device in a CCID standard mode through a built-in USB module. The high-performance microprocessor uses a 32 bit high-performance single chip microcomputer. The portable card reader uses a USB module interface for power supply, deletes the original power supply, greatly reduces the volume, reduces power consumption, and is convenient to carry. The portable card reader uses the high-performance 32 bit microcomputer, has good data processing capability and storage performance, is internally provided with the USB module, saves a special USB controller, and improves system stability.
Description
Technical field
The utility model belongs to electric system sale of electricity equipment technical field, in particular a kind of portable card reader.
Background technology
In the sale of electricity card reader of electric system at present, as shown in Figure 1, card reader comprises power module, common single-chip microcomputer, ISO7816 standard dop, wherein, the external 220V power supply of power module, give the power supply of common single-chip microcomputer and ISO7816 standard dop, common single-chip microcomputer is connected with ISO7816 standard dop, reads the data of ISO7816 standard dop, and common single-chip microcomputer adopts the serial communication equipment connection of serial line interface and outside.Heavier being not easy to of card reader carried, and transfer rate is low, and communications protocol does not possess interchangeability, is difficult to realize that equipment shares, and is not easy to be widely used, and plant factor is very low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of portable card reader is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of portable card reader, consisted of by high-performance microprocessor and ISO7816 standard dop, high-performance microprocessor is connected with ISO7816 standard dop, read ISO7816 standard dop data, high-performance microprocessor is realized communication by built-in USB module with CCID protocol mode and external host device.
And described high-performance microprocessor adopts 32 High Performance SCMs.
Advantage of the present utility model and good effect are:
1, the utility model adopts the USB interface power supply, not independent designing power supply, and high-performance 32-bit processor and peripheral resistance, electric capacity, crystal oscillator all adopt the paster encapsulation, greatly reduce volume, have reduced power consumption, are easy to carry.
2, the utility model adopts the high-performance 32-bit microprocessor, possesses good data-handling capacity and memory property, and the internal USB module has been saved special USB controller, has further reduced board area, has improved system reliability.
3, portable card reader of the present utility model has adopted CCID agreement and the external unit communication that USB interface realizes, supports the CCID driving, make device fabrication manufacturer easily application meet the equipment of CCID interface standard.
Description of drawings
Fig. 1 is the module catenation principle block diagram of original card reader;
Fig. 2 is the module catenation principle block diagram of the utility model portable card reader.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
Therefore embodiment described in the utility model is illustrative, rather than determinate, can not be with embodiment of the present utility model as to restriction of the present utility model.
A kind of portable card reader, as shown in Figure 2, consisted of by high-performance microprocessor and ISO7816 standard dop, high-performance microprocessor is connected with ISO7816 standard dop and reads ISO7816 standard dop data, and high-performance microprocessor is realized communication by built-in USB module with CCID protocol mode and external host device.
In example of the present utility model, described high-performance microprocessor adopts 32 High Performance SCMs, possesses good data-handling capacity and memory property, simultaneously, has saved special USB controller, has further reduced board area, has improved system reliability.Portable card reader of the present utility model adopts the USB Power supply, there is no special feed circuit, and high-performance processor, resistance, electric capacity, crystal oscillator all adopt the paster encapsulation, have reduced power consumption.
In example of the present utility model, the utility model equipment is connected with external host device or other embedded device by the USB module interface, meets the data communication of CCID standard.
Microsoft provides and supports the CCID driving on its Windows 2000 and above operating system, make device fabrication manufacturer easily application meet the equipment of CCID interface standard.Simultaneously, the CCID interface standard is supported PC(Personal Computer-personal computer)/SC(Smart Card-smart card) interface interchange, make numerous developers develop operation to information safety devices easily, on numerous versions of other open source operating system such as LINUX, also having many CCID that increase income to drive can be for developer and user.
