Embodiment Construction
[0053] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0054] First of all, let me explain that the mobile terminal that uses the mobile payment implementation method of the present invention for mobile payment must first be calibrated, and the calibrated mobile terminal can use the mobile payment implementation method of the present invention for mobile payment. Regarding the calibration method and process, we are in It will be explained later.
[0055] The implementation method of mobile payment of the present invention comprises the following steps:
[0056] Step 101, when a mobile terminal with a dual-frequency SIM card enters the set card reading range of the card reader, the dual-frequency SIM card receives the wireless test signal of the first frequency transmitt...

The invention relates to a method and a system for implementing card-read operation. The method for implementing the card-read operation includes: a card-read device setting a card-read range, emitting a radio test signal of a first frequency, when a mobile terminal with a double-frequency SIM (Subscriber Identity Module) card enters the set card-read range of the card-read device, receiving the radio test signal of the first frequency, and detecting the field intensity of the radio test signal, the double-frequency SIM card comparing the field intensity of the radio test signal of the first frequency with a card swiping threshold value stored by the double-frequency SIM card per se, and sending the identity information of the double-frequency SIM card per se in the form of a radio signal of a second frequency if the field intensity of the radio test signal of the first frequency is larger than the card swiping threshold value; receiving the radio signal of the second frequency by the card-read device to acquire the identity information of the double-frequency SIM card, and sending out the identity information by the card-read device in the form of a first frequency signal; and receiving the first frequency signal by the double-frequency SIM card to acquire identity information from the first frequency signal, and comparing the identity information with the identity information stored by the double-frequency SIM card per se by the double-frequency SIM card, and allowing card reading if both of the identity information are consistent. By means of the method and the system disclosed by the invention, the correctness of communication distance control in the card-read operation is ensured and the reliability of the card-read operation is improved.
Description
technical field [0001] The invention relates to the field of electronic payment, in particular to a method for realizing mobile payment and a mobile payment system. Background technique [0002] The passive RFID (Radio Frequency Identification, radio frequency identification) technology using 13.56 MHz is very mature. The 13.56MHz passive RFID card obtains working energy from the 13.56MHz magnetic field emitted by the card reader, and can work without additional power supply to complete the operation of electronic payment. For example, the bus cards currently in use in large quantities. The form of the card reader antenna coil in this way determines the characteristic that the magnetic field energy of 13.56MHz decays rapidly as the distance between the card and the card reader increases, that is, the near field characteristic. The near-field characteristic is: the magnetic field strength is inversely proportional to the third power of the distance. As a result, when the 1...
