The external memory system card may include a smart media card (SMC), a secure digital card (SDC), a compact flash card (CFC), a multi media card (MMC), a memory system stick (MS), an extreme digital card (XDC), and a trans flash card (TFC). Depending on the embodiment, the mobile electronic device 1 may be a mobile phone, or a personal digital assistant (PDA), among other portable electronic devices with a communication function.
In one embodiment, the system 10 includes a connecting module 110, a login module 111, a determining module 112, a receiving module 113, a sending module 114, and a prompting module 115. One or more computerized codes of the modules 110-115 are stored in the memory system 12. One or more general purpose or specialized processors, such as a processor 116 executes the computerized codes of the modules 110-115 to provide one or more operations of the system 10.
The connecting module 110 is operable to establish a wireless communication connection between the credit card terminal 30 and the credit card system 20. As mentioned above, the connecting module 110 establishes the communication connection with the credit card terminal 30 and the credit card system 20 wirelessly.
The login module 111 is operable to receive a credit card number and a password input by a user of the credit card, so as to log into the credit card system 20. In one embodiment, the user may press one or more buttons on the mobile electronic device 1 to input credit the card number and the password. In another embodiment, the mobile electronic device 1 may comprise a touch panel to receive user input. As shown in FIG. 3, the user inputs the credit card number and the password in a login interface 300 to log into the credit card system 20.
The determining module 112 is operable to determine if the credit card number and the password are correct.
The receiving module 113 is operable to receive a two-dimensional barcode 400 (refer to FIG. 4) generated by the credit card system 20, and to display the two-dimensional barcode 400 on the display device 14 of the mobile electronic device 1, in response to a determination that the credit card number and the password are correct. The two-dimensional barcode 400 comprises authorization information and is displayed on the display device 14 of the mobile electronic device 1. The authorization information includes a name of the credit cardholder, a credit card number, an issued date of the credit card, an expired date of the credit card, and a timestamp of the authorization information.
The sending module 114 is operable to send the two-dimensional barcode 400 to the credit card terminal 30 to verify validity of the authorization information. In one embodiment, the credit card terminal 30 decodes the two-dimensional barcode 400 to verify validity of the authorization information using a physical barcode reader of the credit card terminal 30, such as a laser scanner, for example. The laser scanner scans the two-dimensional barcode 400 to verify validity of the authorization information. In one embodiment, the sending module 114 sends authorization information of the two-dimensional barcode 400 to the credit card terminal 30 wirelessly (e.g., over a BLUETOOTH connection, a local area network, a GSM network, or a CDMA for mobile communication network.)
The receiving module 113 is further operable to receive a verification result from the credit card terminal 30.
The determining module 112 is further operable to determine if the authorization information is valid according to the verification result. In one embodiment, for example, if the credit card is out of the expired date, or the timestamp of the authorization information is overdue, then the determining module 112 determines that the authorization information is invalid.
The prompting module 115 is operable to display a prompt for prompting the user for payment on the display device 14 of the mobile electronic device 1, in response to a determination that the authorization information is valid. In one embodiment, the prompting module 115 pops up a dialog box on the display device 14 of the mobile electronic device 1 to prompt the user to input an amount to be paid.
