Abstract
A mobile phone terminal integrated with an RFID device, comprising: the system comprises a mobile phone system and a double-interface RFID chip, wherein the double-interface RFID chip comprises a contact interface and a non-contact interface; the mobile phone system is connected with the double-interface RFID chip through the contact interface of the contact interface, and the double-interface RFID chip is communicated with external video reading equipment through the RFID antenna of the non-contact interface. And the antenna of the non-interface is an independent antenna or shares an NFC antenna with a mobile phone system supporting an NFC function. The utility model discloses an in the integrated cell-phone system of two interface RFID chips, extended RFID's application, and the NFC technique that is current relatively, it can support more RFID agreements, and also can use wireless communication function, the advantage of the passive work of full play RFID under the condition that the cell-phone does not have the electricity.
Description
Technical Field
The utility model discloses an integrated cell-phone terminal that has RFID device belongs to communications facilities's technical field.
Background
The RFID is a technology for transmitting energy and communicating by coupling an electromagnetic field and an antenna, is particularly suitable for application of traffic cards, electronic purses and the like due to the characteristics of no need of batteries, high reliability, no mechanical contact, convenience in maintenance and the like, and has the requirement of integrating the RFID function into the mobile phone along with the popularization of the mobile phone. At present, the mobile phone integrating the NFC function simulates the communication signal of an IC card through an NFC chip, wherein the NFC chip is an active chip, and the part of the NFC chip realizes the RFID function, but the NFC scheme has the following technical problems: firstly, the supported RFID protocols are few, and only the ISO14443 and ISO15693 protocols are supported; secondly, when the mobile phone terminal is powered off, the RFID function cannot be used, so that the advantage of passive work of the RFID cannot be exerted.
Disclosure of Invention
Not enough to prior art, the utility model discloses an integrated cell phone terminal who has the RFID device.
The technical scheme of the utility model as follows:
a mobile phone terminal integrated with an RFID device, comprising:
the system comprises a mobile phone system and a double-interface RFID chip, wherein the double-interface RFID chip comprises a contact interface and a non-contact interface;
the mobile phone system is connected with the double-interface RFID chip through the contact interface of the contact interface, and the double-interface RFID chip is communicated with external video reading equipment through the RFID antenna of the non-contact interface.
According to the utility model discloses it is preferred, the antenna that the non-connects the interface is independent antenna, perhaps with support NFC function cell-phone system sharing NFC antenna.
According to the present invention, preferably, the communication protocol of the contact interface in the dual-interface RFID chip is ISO7816 protocol or I2C protocol.
According to the utility model discloses preferred, the radio frequency parameter of the RFID antenna of non-interface in the two interface RFID chips is 13.56MHz or 125 KHz.
The utility model discloses in the integrated cell-phone system of two interface RFID chips, make current mobile phone terminal possess the function of RFID card or label. On one hand, the mobile phone system can manage the chip through the contact interface of the double-interface RFID chip, such as recharging, password and permission setting; on the other hand, the double-interface RFID chip can also communicate with external radio frequency reading equipment through a non-contact interface, such as consumption, authentication and the like, and the non-contact interface does not need power supply support.
The technical advantages of the utility model reside in that:
the application field of the RFID is expanded by integrating the double-interface RFID chip into a mobile phone system, compared with the existing NFC technology, the double-interface RFID chip can support more RFID protocols, and can use a wireless communication function under the condition that the mobile phone is not powered, so that the advantage of passive work of the RFID is fully exerted.

Detailed Description
The present invention will be described in detail below with reference to the following examples and drawings, but is not limited thereto.
Examples 1,
A mobile phone terminal integrated with an RFID device, comprising: the system comprises a mobile phone system and a double-interface RFID chip, wherein the double-interface RFID chip comprises a contact interface and a non-contact interface; the mobile phone system is connected with the double-interface RFID chip through the contact interface of the contact interface, and the double-interface RFID chip is communicated with external video reading equipment through the RFID antenna of the non-contact interface.
And the antenna of the non-interface is an independent antenna or shares an NFC antenna with a mobile phone system supporting an NFC function.
The communication protocol of the contact interface in the double-interface RFID chip is an ISO7816 protocol or an I2C protocol.
And the radio frequency parameter of the RFID antenna of the non-interface in the double-interface RFID chip is 13.56MHz or 125 KHz.
When the operations of downloading the COS of the card, designing the password and the authority, recharging and the like are needed, the mobile phone system passes
The ISO7816 interface orientation double-interface contactless card chip operates the card by data or program.
When detecting that the electromagnetic field of the external RFID working frequency reaches the trigger field intensity, the double-interface RFID chip starts to communicate with the outside through the radio frequency interface to carry out reading, consumption and other operations.
Although the contact interface is ISO7816 protocol, the radio frequency interface is ISO18000-3, and the radio frequency parameter of the RFID antenna is 13.56MHz or 125KHz in this embodiment, the actual contact interface may be any suitable contact communication interface, and the non-contact interface may also use any RFID interface standard. The description of the embodiments does not limit the scope of the claims of the present invention.
