Description

Apparatus and method for NFC tag

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an apparatus and a method for an NFC tag.

Background

The NFC (Near Field Communication) tag includes a coil therein, and can store data. The NFC label is closely sensed by the mobile phone with the NFC function, so that information in the label can be acquired. The content may be a picture, a text (e.g., a URL (Uniform Resource Locator) link, text information, or a string of terminal-executable instructions).

The NFC tag can be used for electronic posters, article tags, rapid modification of mobile phone settings and the like. Because the NFC label reads swiftly and need not the networking, compare the two-dimensional code, more be fit for using the NFC label in environments such as the not good elevator of network signal, subway or underground garage.

Currently, for a read-only type NFC tag, data needs to be updated by manually replacing the tag. For the read-write type NFC tag, it is necessary to update its stored data by means of a point-to-point overwriting via an external device (e.g., an NFC terminal device). For example, in public places such as subways, a user touches the inductive NFC tag with a mobile phone to purchase a commodity. If some kind of commodity is discounted, the maintenance personnel are required to manually replace the commodity with a new commodity price. This results in a high cost of labor and resources for label maintenance.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Fig. 1 is a schematic diagram illustrating a structure of an apparatus for an NFC tag according to some embodiments of the present disclosure. As shown in fig. 1, the apparatus may include a storage unit 102, a conditional trigger unit 104, and a write unit 106.

The storage unit 102 may be used to store data in the form of data groups. The data corresponds to the memory addresses one to one. That is, each datum corresponds to a unique memory address.

The condition triggering unit 104 may be configured to compare at least one of the current time and the recorded accumulated number of times that the NFC tag is sensed with a preset condition, and in a case that the at least one of the current time and the recorded accumulated number of times that the NFC tag is sensed meets the preset condition, trigger the system pointer to point to a storage address corresponding to the preset condition. Here, the preset condition corresponds to a memory address.

The writing unit 106 may be configured to read data corresponding to a storage address pointed by the system pointer from the storage unit 102, and write the read data to an NFC tag (not shown in fig. 1). For example, the write unit 106 and the NFC tag may be connected with an encryption interface.

It should be noted that the writing unit may be connected to one or more NFC tags. When the writing unit is connected to the plurality of NFC tags, corresponding data may be written to the plurality of NFC tags according to the identifiers or addresses of the plurality of NFC tags, respectively.

In the apparatus for an NFC tag of the above embodiment, the storage unit stores data in the form of a data group. The condition triggering unit compares at least one of the current time and the recorded accumulated number of times that the NFC tag is sensed with a preset condition, and triggers the system pointer to point to a storage address corresponding to the preset condition when the at least one of the current time and the recorded accumulated number of times that the NFC tag is sensed conforms to the preset condition. The writing unit reads data corresponding to a storage address pointed by the system pointer from the storage unit and writes the read data to the NFC tag. In this embodiment, the device can automatically switch contents according to the preset conditions after data is input once, and does not need to manually replace the tag or manually refresh the NFC tag one by using the NFC device, so that the device can save the labor and material costs for tag maintenance.

In some embodiments, the preset condition may include a preset time point. The conditional trigger unit 104 may be configured to compare the current time with the preset time point, and trigger the system pointer to point to the storage address corresponding to the preset time point if the current time matches the preset time point (e.g., the current time is equal to or exceeds the preset time point).

For example, a set of time series (unit: YYMMDDHHMMSS (× year × month × day × time × minute × second)) may be set in the condition trigger unit. The condition trigger unit is responsible for comparing the current time with a preset time point, and if the current time is matched with the next preset time point, the system pointer is triggered to point to the next storage address. In this way, the writing unit can read the next data corresponding to the next memory address from the memory unit and write the next data to the NFC tag. The terminal device (e.g., a cell phone) may read the next data from the NFC tag upon sensing the NFC tag.

Taking a scene of discounting the commodity price as an example, under the condition that the current time is 17 preset points, the system pointer points to the next storage address. And the writing unit writes the discounted price data corresponding to the next storage address into the NFC label. When the consumer utilizes cell-phone NFC function response NFC label to pay, will deduct money according to the price after this discounting. Thus, the purpose of automatically discounting the commodities after 17 o' clock every day is achieved.

In some embodiments, the preset condition may include a preset number of times. The condition triggering unit 104 may be configured to compare the recorded accumulated number of times that the NFC tag is sensed with the preset number of times, and trigger the system pointer to point to the storage address corresponding to the preset number of times when the accumulated number of times reaches the preset number of times.

For example, the condition triggering unit may record an accumulated number of times that the NFC tag is sensed, compare the accumulated number of times with a preset number of times, and trigger the system pointer to point to a next storage address when the accumulated number of times reaches the preset number of times. In this way, the writing unit can read the next data corresponding to the next memory address from the memory unit and write the next data to the NFC tag. The terminal device (e.g., a cell phone) may read the next data from the NFC tag upon sensing the NFC tag.

Taking a scenario of discounting the price of the commodity as an example, when the cumulative number of times that the NFC tag is sensed reaches 100 times (indicating that the commodity has been sold 100 times), the system pointer points to the next storage address. And the writing unit writes the discounted price data corresponding to the next storage address into the NFC label. When the consumer utilizes cell-phone NFC function response NFC label to pay, will deduct money according to the price after this discounting. Thus, the purpose of automatically discounting the commodities after being sold 100 times every day is achieved.

In some embodiments, the preset conditions may include a preset time point and a preset number of times. The condition triggering unit 104 may be configured to compare the current time with the preset time point, compare the recorded accumulated number of times that the NFC tag is sensed with the preset number of times, and trigger the system pointer to point to the storage address corresponding to the preset condition when the current time matches the preset time point and the accumulated number of times reaches the preset number of times. In this embodiment, the time and the number of times are combined as a condition, and when both the time and the number of times satisfy respective preset conditions, the system pointer is triggered to point to the storage address corresponding to the preset conditions.

Taking a scene of discounting the commodity price as an example, when the current time is 17 preset points and the cumulative number of times of induction of the NFC tag reaches 100 preset times, the system pointer points to the next storage address. And the writing unit writes the discounted price data corresponding to the next storage address into the NFC label. When the consumer utilizes cell-phone NFC function response NFC label to pay, will deduct money according to the price after this discounting. This achieves the purpose of automatically discounting the merchandise after 17 o' clock per day and after 100 times of sale.

In some embodiments, as shown in fig. 2, the device may also include an NFC tag (e.g., a read-write NFC tag) 208. The NFC tag 208 may be used to store the data that is written for the end device to read from the NFC tag 208. For example, a mobile phone as a terminal device can sense an NFC tag through an NFC function to read written data from the NFC tag.

In some embodiments, as shown in fig. 2, the apparatus may also include a management interface 210. The management interface 210 may be used to receive data or preset conditions from an external device or network and transmit the data to the storage unit 102 or transmit the preset conditions to the condition triggering unit 104. By adding the management interface, external equipment (such as a computer) or a network is connected, so that the configuration of data or preset conditions can be realized, and the content can be managed conveniently.

In some embodiments of the present disclosure, the above-described apparatus may be implemented on the basis of an NFC tag, and may store data content and switch control, thereby implementing content management and automatic update of the NFC tag. Through the control, a group of time sequence, times and corresponding display content can be preset for the NFC label. For example: the NFC label is used for the intelligent advertisement of bus station, can set up 5 group's advertisements, and every minute is the show by turns.

The device of the embodiment of the disclosure can realize local automatic content switching so as to save the labor and material cost of label maintenance. Based on local content dynamic display and content management, a network is not needed, and a remote management platform is not needed, so that the cost is reduced. In addition, the equipment cost of the device for the NFC label is low, so that the device can be widely popularized in a short period.

In step S306, data corresponding to the memory address pointed to by the system pointer is read, and the read data is written to the NFC tag.
