Communication method between mobile terminal and POS terminal, communication system and POS terminal

摘要

A communication method between a mobile terminal and a POS terminal according to the present invention includes a step of encapsulating a broadcast interface for entering broadcast information in the mobile terminal and the POS terminal and a scan interface for acquiring the broadcast information, and a POS terminal. Or, the data broadcast thread of the mobile terminal calls the broadcast interface, enters the broadcast information after encryption into the data payload in the data structure, obtains the encrypted data payload, and encapsulates it to generate the broadcast data packet Broadcasting the broadcast data packet with the ibeacon Bluetooth module; The mobile terminal that enters the broadcast area of Null or the POS terminal that enters the broadcast area of the mobile terminal calls the data reception thread to obtain the broadcast data packet through the callback function of the scan interface using the ibeacon Bluetooth module. Performing decapsulation to obtain an encrypted data payload and then decrypting the encrypted data payload to obtain broadcast information. According to the present invention, data broadcasting and scanning through ibeacon are realized.
