Example 2
As shown in fig. 7, in this embodiment, the NFC and 2.4GHz dual-band communication mobile phone performs data transmission with a service terminal (POS) in a radio frequency manner. The mobile phone is internally provided with an SIM/UIM card with NFC and 2.4G dual-band communication, and the SIM/UIM card and a service terminal carry out information interaction processing through NFC and 2.4G frequency bands.
The service platform is a processing working platform of the one-card service of the mobile phone, and is mainly responsible for processing and managing the one-card service, such as entrance guard, attendance checking, garage, ETC, VIP card, information issuing and collecting, electronic certificate, entrance ticket and the like, and a general platform for processing service information, managing service information, issuing and collecting service information;
the payment platform is a payment settlement platform of an operator, a third-party payment company and the like, mainly processes management and operation of mobile phone payment and settlement services, and performs data interaction with the service platform through a wired or wireless network.
The service terminal: the terminal mainly collects and issues information, performs wireless information exchange with a mobile phone through NFC and 2.4G wireless technologies, receives, confirms and issues related information, and is a terminal supporting double frequency points (NFC and 2.4G). The connection between it and the service platform can be in the form of IP network, serial port or parallel port special line, and wireless communication (such as GPRS, 3G, WIFI, etc.).
In the embodiment, the mobile phone only responds to the same type of information source information when information is interacted, if payment is carried out, the mobile phone receives a payment request of the POS terminal, the mobile phone responds to the request of the POS terminal through NFC, the POS terminal sends the mobile phone information to the service platform and the payment platform, the platform gives processing confirmation, and then the confirmation information is sent to the mobile phone through the POS terminal, so that payment of the mobile phone is realized. The whole process uses the same type of information source signals for payment, and the information source signals are different from signal source information types applied to other 2.4G access controls and the like, and each information source information uses different frequencies and signal source types.
In some remote payment scenes, the NFC technology and the 2.4G technology can be matched with each other, so that the positioning is accurate, the positioning error is reduced, and the payment and the one-card service are accurately and stably realized.
When the intelligent card is installed in a mobile phone, the memory in the card can store the information of a common base card, and can also store some private materials including personal identity information, private business card information, an address book, a bank account number, an insurance number, a medical card number, a small payment account number and the like. Generally, the mobile phone can use all functions of a common mobile phone, and when the mobile phone enters a place provided with a peripheral terminal, the mobile phone becomes various cards which are used by people in daily life.
When a user purchases money in the east and west in a shopping mall, a matched POS sends the signal source type of the user to a service platform, the service platform pushes the signal type to a mobile phone end, a CPU (central processing unit) in an intelligent card calls a processing module with the same type as the signal source, then relevant information stored in a mobile phone card is sent to a receiver of a POS (point of sale) machine by the mobile phone, the receiver sends a password verification request to the user after receiving an account number, the user can input a password by using a key of the mobile phone, the receiver of a bank receiving station requests the user to confirm the payment again after receiving the password, and the user can complete the payment service after selecting the confirmation.
The invention can also be applied to the scenes of door control, garage of the consumer in the community at ordinary times, attendance checking and card punching when the consumer is on duty, and the like. When the peripheral processing end senses that the mobile phone enters the detection area, the signal type of the peripheral processing end is sent to the service platform, the signal type is also pushed to the mobile phone end by the platform, and the same type of module is called to complete the service flow through the processing of the CPU in the card.
Meanwhile, the user can also transmit the electronic business card by using the invention. When the two mobile phones are equipped with the smart card, the signal intensity of the receiving end can be automatically detected by the initiating end as long as the corresponding transmission program is opened, if the two mobile phones are far away from each other, a 2.4G wireless transmission mode is used, otherwise, an NFC mode is called for data transmission.
The invention perfectly combines the mobile payment service and the mobile one-card service, and the user does not need to replace the mobile phone or carry a large number of cards in different application scenes, thereby really realizing the multiple purposes of one machine. In life consumption, the consumption process can be finished only by brushing the mobile phone on the POS in an environment with a peripheral signal source. And places such as access control, garage, company access control and the like in the residential area can be realized only by taking out the mobile phone and brushing one mobile phone. The consumer can conveniently, quickly, safely and simply enjoy more services brought by the mobile phone.
