Embodiment
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
See also Fig. 1, the invention provides a kind of method of writing card, the terminal of the method operation Android system writes card image by the Bluetooth control card reader/writer in card, and described card writing method 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, at first the Android system 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 was arranged, pairing can be avoided occurring being connected on other bluetooth card reader/writer.
Step S13: described terminal is accepted the successful matching information of card reader/writer feedback.
After card reader/writer successfully matches and is connected to the Android system, feed back an information, represent the bluetooth successful connection after the Android system receives.
Step S2: described terminal judges 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 card reader/writer is carried out electrification reset;
