Description

The mobile phone of band radio-frequency (RF) identification chip

Technical field

The utility model relates to a kind of equipment of automatic identification technology, particularly a kind of equipment that wireless radio-frequency identification chip is installed on mobile phone.

Background technology

The mobile phone of UIM chip is housed, mainly is to use its communication function.And automatic identification technology was not relate to the communications field originally.In recent years, the tremendous development of automatic identification technology not only shows the extensive use of bar codes technique, also is embodied in the fast development of radio frequency identification (RFID) technology.This RFID technology with its reading and writing data, storage, anti-adverse environment, false proof and intelligent aspect being unsurpassed in excellence property, the gesture that replaces traditional barcode technology is arranged greatly.Particularly since the Mifare RFID chip new product of releasing 13.56MHz, because it adopts 128 byte Advanced Encryption Standards (AES), 48 bytes that adopt of Classic chip compared with the past, its arithmetic safety is stronger, be difficult to crack, but specialized designs is used for gate inhibition's control and payment is used.

The application of existing 13.56MHz RFID chip is mainly used in the systems such as work attendance, gate inhibition, consumption and small amount payment.During use, this RFID chip is connected with one group of aerial coil by lead, transmits by antenna, sends corresponding application on the application corresponding system, promptly so-called " Card Reader ".Transfer wire between chip and antenna in use very easily fractures, even there is cardboard to rely on, bends repeatedly less than tens of and time promptly can fracture.Could utilize immobilized mode, chip be installed to mobile phone get on! Two kinds of functions can also be united two into one? but transfer wire and antenna tail can't install to mobile phone and get on.So, could directly use the sky cotton suittings of mobile phone? promptly be to be designed for the RFID chip of certain or multiple systems especially, to be installed on the mobile phone, by the triggering of cellular phone power supplies, strengthen the intensity of mobile phone radio frequency and send signal, corresponding card reader can be received.This is undoubtedly a kind of improved procedure.It is the 13.56MHz radiofrequency signal with the RFID chip, by associated antenna in cellular phone power supplies and the power supply and radio frequency expansion instrument (or radio-frequency (RF) transmitter), sends corresponding application to card reader.Obviously, when battery of mobile phone does not have electricity, can't launch, its defective is conspicuous: a, when mobile phone does not have electricity, and corresponding intelligent card can't be used; B., can't carry out the stored value card payment on the mobile phone, the E-Payment that can not consume; C., the Card Reader success rate is not high, influenced the stability of mobile-phone payment function.In addition, chip connects, still can't solve with the direct of antenna on being in bonnet.It has been generally acknowledged that cell phone mainboard can not change and touch easily, uniquely in the fuselage can accept external element, had only chip carrier one place.

The utility model content

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, can carry out transmission and the mobile phone that use stable band radio-frequency (RF) identification chip of less radio-frequency and provide a kind of to smart mobile phone chips.

The purpose of this utility model can reach by following measure:

A kind of mobile phone with radio-frequency (RF) identification chip, it is a mobile phone that tool communication function chip is installed, include fuselage, be installed in cell phone mainboard and battery of mobile phone in the fuselage, and cell phone rear cover, it is characterized in that, a wireless radio-frequency identification chip also is installed in fuselage, this piece wireless radio-frequency identification chip by below battery of mobile phone and be positioned at one on cell phone mainboard cover elasticity transmitting device, connects with aerial coil on being installed in cell phone rear cover.

Above-mentioned elasticity transmitting device, comprise radio frequency contact, the first elastic metallic tie point on the fuselage or the second elastic metallic tie point on the another location connected with described wireless radio-frequency identification chip with contact with this above-mentioned elastic metallic tie point, be positioned at metal connection point corresponding on the cell phone rear cover, and the transfer wire that below battery of mobile phone, also passes through cell phone mainboard; This transfer wire is connected the first elastic metallic tie point on radio frequency contact and the fuselage or the second elastic metallic tie point, by the first elastic metallic tie point on the fuselage, or the second elastic metallic tie point, with contacting between the metal connection point on the bonnet, connect with aerial coil on the bonnet again.

Above-mentioned aerial coil is fixed on the cell phone rear cover, perhaps is implanted to the cell phone rear cover the inside.

The rf frequency of above-mentioned wireless radio-frequency identification chip is 13.56MHz.

The mobile phone of the utility model band RFID chip has following advantage:

1. function is two-in-one, enlarges the scope of application, convenient user.The utility model mobile phone is with the communication function of UIM chip, unite two into one with the automatic identification technology function of RFID chip, be convenient to that the user communicates, work attendance, gate inhibition, small amount consumption and mobile-phone payment intelligent use such as (as the Canton All-in-Card of taking pubic transport are paid by mails), as long as " brush " be mobile phone once, a lot of things are once settled, make things convenient for the user greatly, improve the quality of living.

2. be convenient to mobile phone and operate under unrestricted environment, no matter whether mobile phone has electricity, all can discern the intelligence of mobile phone and use; For the mobile-phone payment function, realized accessible payment.

3. improved the stability of using.It can carry out effective intelligent RF emission to the Card Reader of relevant intelligent program, allows card reader read corresponding information more like clockwork, strengthens the stability of its application.And, improve through this, improved the use value of smart mobile phone GSM and CDMA chip card, increase its operation income.

4. broken through technology prejudice.No matter be the inside and outside personage of electronic communication industry, think all that generally the mainboard of mobile phone can not be reformed easily.Should get rid of the antenna tail between RFID chip and the antenna, realize the connection from chip carrier to the bonnet antenna again, be impossible, because can not press a lead below battery; Be placed on above the battery, can't be connected to the radio frequency contact in the fuselage again.So, can only utilize battery of mobile phone to transmit, but at that rate, when mobile phone does not have electricity, just can't realize wireless radio frequency identification function.Mobile phone of the present utility model has overcome above-mentioned technology prejudice, makes transfer wire through cell phone mainboard, by a cover elasticity transmitting device, has realized directly being connected with antenna, has avoided the defective of prior art.Greatly improve the stability of transmission.

The utility model is done the narration of further indefiniteness below in conjunction with drawings and Examples.
