Description
Technical field
The utility model relates to a kind of the short distance wireless communication technology field, particularly relates to a kind of NFC label with passive switch.
Background technology
The short distance wireless communication technology (Near Field Communication, NFC) be a kind of short distance high frequency wireless communication technology being developed by non-contact radio-frequency identification (RFID) and the Technology Integration that interconnects and come, by combining induction card reader on one chip, induction type card and point-to-point function, can carry out identifying and exchanges data with compatible equipment in short distance.Compared with infrared communication, Bluetooth communication, NFC have employed unique signal attenuation technique, and thus can communicate in very short distance (such as 10cm), be a kind of in-plant secret communication mode.NFC has more security because communication distance is short, is very suitable for the application scenario such as identification, secure payment.At present, NFC is widely used in identification, checks card, gate inhibition, secure log, the field such as logistics and payment, as I.D., mass transit card, purchase card, campus card, bluetooth earphone, electronic tag etc.
NFC device comprises NFC card reader 4 and NFC label 1, as shown in Figure 1, existing NFC label 1 comprises NFC label chip 2 and NFC antenna coil 3, its principle of work is: when NFC card reader is near NFC label, NFC card reader sends electromagnetic energy to NFC label, this electromagnetic energy of NFC antenna coil coupling in NFC label is also delivered in the NFC label chip be connected with NFC antenna coil, and this electromagnetic energy to be converted into the power supply required for the microcontroller of its inside, the circuit such as modulator-demodular unit and storer by rectification circuit by NFC label chip; When the circuit such as microcontroller, modulator-demodular unit and storer are started working after power, the information stored can be sent to NFC card reader by NFC antenna coil in NFC label chip.
An advantage of common NFC label self does not need to possess outfit power supply, the electromagnetic energy launched by receiving NFC card reader converts power supply to, but so just there is a problem, as long as NFC card reader is near NFC label, NFC label will be activated, and its information stored will send to NFC card reader automatically.Such as, on bus people how crowded in, mass transit card may repeatedly cause near card reader repeating to swipe the card, that is, NFC card reader is unconditional reading NFC label internal information, is easy to like this cause user benefit to incur loss or information leakage.
For this reason, a kind of NFC label of belt switch has been there is in prior art, a kind ofly control the method for NFC label and controlled NFC label as disclosed in Chinese patent literature CN103413165A, described method comprises: produce for making electronic switch disconnect or the disconnection control signal of conducting or conductivity control signal; Described disconnection control signal or conductivity control signal are applied to on the electronic switch of the NFC antenna coils from parallel connection of coils in NFC label, thus enable or forbid that the electromagnetic energy be coupled in described NFC antenna coil is to the NFC label chip transmission in described NFC label.Described controlled NFC label comprises: NFC label main body, with the electronic switch of the NFC antenna coils from parallel connection of coils in NFC label main body and disconnect/the electronic switch control circuit of conductivity control signal for this electronic switch produces.
Although above-mentioned NFC label can open switch by arranging electronic switch when needs use NFC label, make NFC card reader reading NFC label with good conditionsi, but what this NFC label adopted is electronic switch, need to be equipped with power supply and produce the electric signal driving electronic switch action, the opening of NFC label could be realized, close, and NFC label be equipped with this active switch undoubtedly can larger production design difficulty, make product structure complicated, increase cost of products.
Utility model content
Technical problem to be solved in the utility model is that existing NFC label adopts active switch, and product structure is complicated, increase cost of products, and provides a kind of product to change the NFC label of the band passive switch little, cost is low.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of NFC label with passive switch, comprise NFC label chip and NFC antenna coil, also comprise passive switch, described passive switch and described NFC label chip, described NFC antenna coils connected in series, the operating key of described passive switch is arranged at the outside of described NFC label.
In the NFC label of above-mentioned band passive switch, described passive switch is touch-switch.
In the NFC label of above-mentioned band passive switch, described passive switch adopts carbon Key Pad.
In the NFC label of above-mentioned band passive switch, described passive switch adopts the young sheet button of pot.
In the NFC label of above-mentioned band passive switch, described passive switch is self-lock switch.
In the NFC label of above-mentioned band passive switch, described passive switch adopts toggle switch.
Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) NFC label of band passive switch of the present utility model; comprise the passive switch with NFC label chip, NFC antenna coils connected in series; the On/Off that passive switch controls NFC label can be operated; can the using state of manual control NFC label; the reading of NFC label is made to be with good conditionsi; thus avoid unexpected situation about reading to occur; protect the interests of user and the security of information, the NFC label of band passive switch of the present utility model can be used in the multiple occasions such as mobile phone, mass transit card, Payment Card, purchase card, bluetooth earphone.
(2) NFC label of band passive switch of the present utility model, a passive switch of only need connecting, little to the change of existing product, compared with prior art structure is simple, cost is low.
(3) NFC label of band passive switch of the present utility model, wherein passive switch selects touch-switch or self-lock switch, easy to use, simple to operate, with low cost.
