Embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
See also Fig. 1, the described card of writing comprises: step S1: described terminal connects card reader/writer by bluetooth.
See also Fig. 2, step S1 comprises: step S11: described terminal sends link information by bluetooth to card reader/writer.
When needs used, the Android system at first sent link information to card reader/writer, and card reader/writer is ready to be connected with the Android system like this.
Step S12: described terminal and bluetooth card reader/writer match.
After card reader/writer receives link information, card reader/writer and Android system match, the effect of pairing is the correctness that guarantees connection, because connecting by bluetooth is wireless connections, when a plurality of bluetooth card reader/writer, pairing can be avoided occurring being connected on other the bluetooth card reader/writer.
Step S13: described terminal is accepted the successful matching information of card reader/writer feedback.
Card reader/writer successfully matches and is connected to after the Android system, feeds back an information, represents the bluetooth successful connection after the Android system receives.
Step S2: described terminal is judged type of card by card reader/writer.
See also Fig. 3, step S2 comprises: step S21: described terminal sends instruction by bluetooth and to card reader/writer the card in the card reader/writer is carried out electrification reset; Electrification reset plays an initialized effect here, and the chip of card is restarted.
Step S22: described terminal is accepted the ATR information of card reader/writer feedback by bluetooth.
Can produce a series of character string (being ATR information) after the chip reset of card, card reader/writer is transferred to the Android system with these ATR information, and the Android system judges the type of card by ATR information.
Step S3: described terminal obtains the card read-write state to judge that can card write by card reader/writer.
See also Fig. 4, step S3 comprises: step S31: described terminal sends instruction to card reader/writer by bluetooth, reads card mode information by card reader/writer.
Some data has represented the status information of card in the chip of card, and card reader/writer can read this part information.
Step S32: described terminal is accepted the card mode information of card reader/writer feedback by bluetooth.
The card mode information that the Android system receives feedback is namely known the state of card, judges then whether the storage of card is full.
Step S33: can described terminal judges card write.
Step S4: carry out card to card reader/writer and write card image if can be then described terminal sends instruction.In the present embodiment, if can then can not write the transmission of card instruction, in other embodiments, can add other response mode, such as sending prompting.
See also Fig. 5, step S4 comprises: step S41: described terminal is carried out card to card reader/writer with the control card reader/writer by bluetooth transmission instruction and is write card image.
Step S42: described terminal is write the card successful information by what bluetooth was accepted card reader/writer feedback.
When writing when finishing, card reader/writer can feed back one and write the card successful information, just can learn after the Android system has received to have write successfully.
Once writing in the card process normally, step S4 need carry out repeatedly.
The utility model also provides a kind of read-write card system, sees also Fig. 6, and described read-write card system comprises terminal 2 and bluetooth card reader/writer 1, and described terminal 2 and described card reader/writer 1 are connected by bluetooth.
Bluetooth card reader/writer 1, described bluetooth card reader/writer comprises controller 11, signal level converter 12, IC-card seat 13, bluetooth serial ports converter 14, power supply 15 and electric pressure converter 16.
Signal level converter 12, described signal level converter 12 connects described controller 11, the signal that described controller 11 is sent carries out level conversion, because the level of the signal of controller 11 outputs is different with the level of IC-card seat, so need signal level converter 12 to change.In the present embodiment,
IC-card seat 13, described IC-card seat 13 connects described signal level converter 12, and 13 pairs of IC-cards of described IC-card seat carry out read-write operation.
Bluetooth serial ports converter 14, described bluetooth serial ports converter 14 connects described controller 11, and described bluetooth serial ports converter 14 is accepted instruction and is converted the signal type of controller 11 to.
Described terminal 2 comprises the processor (not shown) of operation Android system.
The Android system of terminal 2 sends instruction by bluetooth to bluetooth card reader/writer 1, matches, checks that card mode information has write etc. function.Concrete principle of work sees also above about writing the step introduction of card, does not do at this and gives unnecessary details.
In sum, the utility model transmits information between card reader/writer and the Android system by bluetooth, thereby realized the wireless connections between Android system and the card reader/writer, avoided the problem of mobility difference of the mobile self-aided terminal of employing of the prior art Android system.
The above only is preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model.Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
