Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
At present, after the NFC tag is written in, reading can be carried out on the equipment which accords with the reading condition, the read equipment cannot be distinguished, and reading disorder can be caused on scenes with strict requirements on the reading equipment.
For example, for some special instructions (such as generation of a visitor code), only triggering is needed on the non-setting device, but once the NFC tag enters the sensing range of the setting device, the special instructions are triggered, and it cannot be avoided that the setting device triggers the special instructions which are not needed to be triggered.
In view of the above situation, at present, to solve the above problems, the method mainly adopted is: in order to distinguish the reading device, normally, the NFC data of the reading device is modified. For example: the device A can identify the NFC label, and the device B cannot read the NFC label by modifying the authority or modifying the internal program. However, the above operation is very troublesome and requires a separate and targeted setting. In addition, when the NFC tag needs to be read again by the B device, the program needs to be rewritten to enable reading. The use difficulty is high, and the process is complicated.
Based on this, the present embodiment provides an NFC triggering method, an apparatus, an electronic device, and a storage medium, and when an NFC tag is sensed, whether the NFC tag belongs to a prohibited tag is determined; the NFC device prohibits reading instructions from the prohibited tag; when the NFC tag does not belong to the forbidden tag, reading and executing an instruction from the NFC tag; and when the NFC tag belongs to a forbidden tag, forbidding to read the instruction from the NFC tag. By adopting the scheme provided by the invention, only the NFC label which does not belong to the forbidden label is read and the instruction is completed after the forbidden label is set, and the targeted reading triggered by the NFC is realized, so that the special scene use requirement is realized, and the use experience of a user is improved.
Specifically, an embodiment of the present invention provides an NFC triggering method, which is applied to an NFC device, and as shown in fig. 1, the method includes:
step 101: when an NFC label is induced, judging whether the NFC label belongs to a forbidden label or not; the NFC device prohibits reading instructions from the prohibited tag;
step 102: when the NFC tag does not belong to the forbidden tag, reading and executing an instruction from the NFC tag;
step 103: and when the NFC beacon tag belongs to a prohibited tag, prohibiting reading of the instruction from the NFC tag.
In particular, Near Field Communication (NFC) is a fast short-distance high-frequency wireless Communication technology that operates at a frequency of 13.56MHz (megahertz), has a Communication connection establishment time of less than 1 second, and has a Communication distance generally limited to 10 centimeters.
The NFC label comprises an NFC coil and an NFC chip and can be communicated with the NFC induction equipment. The NFC coil is a coil which is formed by surrounding an NFC antenna into a circle or an ellipse or any other shape and is used for capturing electric energy from an electromagnetic field and carrying out transceiving communication with smaller data volume by demodulating or modulating the electromagnetic field. And the NFC chip is used for storing the chip of the circuit module of the information. The NFC sensing device may be an NFC reader, or may also be an electronic device supporting NFC communication, such as a mobile phone supporting NFC communication. When NFC equipment induction equipment is close to the NFC label, NFC induction equipment sends electromagnetic energy to the NFC label, and the NFC coil on the NFC label couples this electromagnetic energy and passes it to the NFC chip that links to each other with the NFC coil in, and the NFC chip passes through rectifier circuit and turns into the required power of circuits such as its inside microcontroller, modem and memory with this electromagnetic energy. When the circuits such as the microcontroller, the modem, and the memory start to operate after power-on, information stored in the NFC chip can be transmitted to the NFC inductive device through the NFC coil.
For example, the NFC tag may communicate with a portable communication device such as a mobile phone with an NFC function, so as to change an operating state of the device or open related software and settings. The NFC label is stored with data written in advance by a mobile phone (with an NFC function), when the mobile phone with the NFC function is close to the NFC label, the mobile phone senses the NFC label and effectively recognizes the NFC label, the working state of the mobile phone can be converted through mobile phone software, if navigation is automatically opened, the mobile phone automatically enters a meeting mode, automatically connects an appointed Wifi hotspot, automatically listens to music, automatically closes a Wifi signal, enters a flight mode and the like.
In practical application, when the NFC tag belongs to a prohibited tag, the NFC device prohibits reading of instructions from the NFC tag.
Further, in an embodiment, the determining whether the NFC tag belongs to a prohibited tag includes:
acquiring identification information of the NFC tag;
judging whether the identification information is stored in the identification information set of the forbidden tag or not according to the identification information;
and when the identification information is stored in the identification information set of the forbidden tag, judging that the NFC tag corresponding to the identification information belongs to the forbidden tag.
Here, the identification information may be an ID of the NFC tag, which is used to distinguish the NFC tag from other NFC tags. Generally, one NFC tag is provided with one ID.
Further, in an embodiment, before the NFC tag is sensed, the method further includes:
acquiring identification information of the NFC label after data writing operation of the NFC label is completed;
storing the identification information in an identification information set of the prohibited tag.
According to the NFC triggering method provided by the embodiment of the invention, when an NFC label is induced, whether the NFC label belongs to a forbidden label is judged; the NFC device prohibits reading instructions from the prohibited tag; when the NFC tag does not belong to the forbidden tag, reading and executing an instruction from the NFC tag; and when the NFC beacon tag belongs to a prohibited tag, prohibiting reading of the instruction from the NFC tag. By adopting the scheme provided by the invention, only the NFC label which does not belong to the forbidden label is read and the instruction is completed after the forbidden label is set, and the targeted reading triggered by the NFC is realized, so that the special scene use requirement is realized, and the use experience of a user is improved.
An embodiment of the present invention further provides another NFC triggering method, which is applied to an NFC tag, and as shown in fig. 2, the method includes:
step 201: when the NFC equipment is induced, judging whether the NFC equipment belongs to forbidden equipment or not; the NFC tag prohibits sending instructions to the prohibiting device;
step 202: when the NFC equipment does not belong to forbidden equipment, sending an instruction to the NFC equipment so that the NFC equipment receives and executes the instruction;
step 203: and when the NFC equipment belongs to a forbidden device, forbidding sending of an instruction to the NFC equipment.

In practical application, when the NFC equipment belongs to forbidden equipment, the NFC tag forbids sending instructions to the NFC equipment.
Further, in an embodiment, the determining whether the NFC device belongs to a prohibited device includes:
acquiring identification information of the NFC equipment;
judging whether the identification information is stored in an identification information set of the forbidden device or not according to the identification information;
and when the identification information is stored in the identification information set of the forbidden device, judging that the NFC device corresponding to the identification information belongs to the forbidden device.
Here, the identification information may be an ID of the NFC device, which is used to distinguish the NFC device from other NFC devices. Generally, one NFC device is correspondingly provided with one ID.
Further, in an embodiment, before the NFC device is sensed, the method further includes:
when the data writing operation on the designated NFC label is completed, acquiring the identification information of the NFC equipment in which the data writing operation is performed;
storing the identification information in a set of identification information of the forbidden device.
According to the NFC triggering method provided by the embodiment of the invention, when the NFC equipment is induced, whether the NFC equipment belongs to forbidden equipment is judged; the NFC tag is prohibited from sending instructions to the prohibition device; when the NFC equipment does not belong to forbidden equipment, sending an instruction to the NFC equipment so that the NFC equipment receives and executes the instruction; and when the NFC equipment belongs to a forbidden device, forbidding sending of an instruction to the NFC equipment. By adopting the scheme provided by the invention, the NFC equipment which does not belong to the forbidden equipment can be sent with the instruction after the forbidden equipment is set, and the targeted reading triggered by the NFC equipment is realized, so that the special scene use requirement is realized, and the use experience of a user is improved.
The present invention will be described in further detail with reference to the following application examples.
For some scenes with strict requirements on reading devices, reading confusion is caused because reading devices cannot be distinguished, and the embodiment of the application provides an NFC triggering method.
Specifically, the method may be the first manner as follows:
after the NFC device writes a special instruction (only an instruction triggered on a non-writing device) into the NFC tag, the ID of the NFC tag is stored in the NFC device, and the ID is set as the tag from which the instruction is forbidden to be read.
When any NFC label enters the induction range of the NFC equipment, acquiring the ID of the NFC label, and judging whether the NFC label is a label from which an instruction is forbidden to be read; if so, not reading the instruction in the NFC label; and if not, reading the instruction in the NFC label.
Here, an example will be explained. The mobile phone a writes 1 "generate guest code" instruction in a certain NFC tag, the ID of the certain NFC tag is "409 xx 6", and the mobile phone a sets "409 xx 6" as a tag from which instruction reading is prohibited. When an NFC tag enters the sensing range of the mobile phone a, the mobile phone a first obtains the ID of the NFC tag, determines whether the ID is "409 xx 6", and if the determination result is "yes", does not read the instruction in the tag. When the tag with the ID of "409 xx 6" enters the sensing range of the mobile phone B, the mobile phone B can directly read the instruction in the tag to generate a visitor code in the mobile phone B.
In addition, the above functions can also be realized on the NFC tag side. When any NFC equipment enters the induction range of the NFC label, the ID of the NFC equipment is acquired, and whether the NFC equipment is a label (such as a visitor code) which prohibits sending instructions or not is judged; if so, not sending the instruction in the NFC label; and if not, sending an instruction in the NFC label.
In addition, the method may be a second method:
referring to fig. 3, when an NFC tag is sensed, information in the NFC tag is acquired, including a tag ID and an instruction combination; searching writing information of the history writing operation on the NFC label, wherein the writing information comprises: NFC tag information; the write operation may be a set, which includes writing to a plurality of NFC tags, and whether there is write information of the same ID is searched from a set of historical write information; if yes, not triggering. If the same ID does not exist, the instruction combination is triggered directly.
According to the embodiment, the instruction in the NFC label can be triggered only by the non-set equipment, the use requirements under certain special scenes are met, and the use experience of a user is improved.
