Abstract
The utility model provides a reader-writer capable of supporting contact cards and contactless cards (electronic tags) simultaneously. The utility model provides a proposal as follows: the reader-writer is provided with a contact card circuit and a contactless card circuit, and further provided with a controller chip connected with the contact card circuit and the contactless card circuit respectively; and the contact card and the contactless card are provided with a USB interface respectively for the connection with a computer. The utility model has the benefits of integrating the advantages of the contact type and the contactless type and avoiding the disadvantages of the both, and is suitable for more occasions.
Description
Technical field
The utility model relates to a kind of intelligent card reader, particularly a kind ofly can read non-contact card (electronic tag) and the read write line that contacts card simultaneously.
Background technology
The read write line that is using in the market has contact and contactless two kinds of read-write equipments.The shortcoming of contact is to swipe the card usually cumbersomely, and the action of plug-in card is incured loss through delay, and causes wearing and tearing easily.Contactless security is lower, and antijamming capability is relatively poor.Therefore using together in conjunction with the relative merits of two kinds of cards to make card system more reliable and more stable.
The utility model content
For solving foregoing problems, the utility model provides a kind of read write line that can support contact card and non-contact card (electronic tag) simultaneously; Its scheme is: this read write line is respectively arranged with contact card circuit and non-contact card circuit, and a controller chip is set is connected with the non-contact card circuit with contact card circuit respectively, blocks for simultaneously contact with non-contact card a USB interface to be set respectively to be connected with computer.
Superior effect of the present utility model has been contact compatible and contactless both advantage, and the deficiency of also having avoided both respectively to have simultaneously is applicable to more occasions.
Description of drawings
Accompanying drawing 1 is a block scheme of the present utility model.
Accompanying drawing 2 basic circuit diagrams.
Embodiment
See also shown in the accompanying drawing, a control chip 1 is set is connected with contact dop 3 (contact card circuit) with radio circuit (non-contact card circuit) respectively, other is provided with USB interface 4 by control chip 1 control, is connected with computer.
The contact cartoon is crossed a testing circuit and is detected whether the card insertion is arranged, and has card insertion back to block for contact by control signal wire and powers on.Pass through 7816 interfaces then and contact card-to-card communication, achieve a butt joint and touch the operation of card.
Noncontact card (electronic tag) is then communicated by letter with radio frequency chip 2 by the bus interface of control chip, the modulation amplitude and the pattern of control radio frequency chip 2.Send the data to non-contact card
(electronic tag) realizes the operation to non-contact card.
Adopt USB interface with being connected of computer, card reader control chip integration USB transceiver opens up 2 pairs of different USB end points with non-contact card for simultaneously the contact card, and they can independently be worked simultaneously.Control chip 1 adopts the SPI interface to be connected with radio frequency chip 2, after receiving the order of read-write electronic tag, operates by 2 pairs of electronic tags of radio frequency chip.In contact card read-write communication aspects is to cooperate timer to sample by external interrupt to realize and 7816 interface communications that contact card.
All the chip model is as follows:
| The chip model | Effect | Manufacturer |
| C8051F340 | Control chip | Silicon Labs |
| FM1725 | The electronic tag radio frequency chip | Fudan University's microelectronics |
Claims (1)
1, a kind of read write line that can operate contact card and electronic tag simultaneously, it is characterized in that: this read write line is respectively arranged with contact card circuit and non-contact card circuit, and a controller chip is set is connected with the non-contact card circuit with contact card circuit respectively, block for simultaneously contact a USB interface to be set respectively to be connected with computer with non-contact card.
