Description
Technical Field
[0001] The utility model belongs to the technical field of hanging tags, and in particular relates to an anti-theft intelligent hanging tag. Background Art
[0002] Nowadays, shopping has become a popular pastime for people. The offline experience is evolving towards smarter and more efficient experiences. Leveraging technological advancements, more and more physical stores are transforming themselves, moving towards intelligent operations to improve management efficiency and reduce operating costs. This led to the emergence of RFID hang tags. By working with RFID readers, they distinguish between on-sale and sold items using signal data to determine whether they are operating properly. While this provides some basic theft prevention measures, it lacks a tamper alarm, leaving it with a security flaw. The single-source RFID technology also limits product management. Store staff can only check whether an item has been sold through the platform, but cannot determine whether it is in its designated location, making it less intelligent. Furthermore, many physical stores still use traditional plastic hang tags, which only serve to protect new products and lack the ability to prevent theft, let alone intelligent management. Existing commercial hang tags also have a short lifespan and are generally disposable, constantly changing with the product, which is also unfavorable to environmental protection.

[0034] The working principle of this utility model is as follows:
[0035] like Figure 1-Figure 5 As shown, the anti-theft smart tag proposed by the utility model includes:
[0036] BLE RF circuit: This circuit includes a wireless transceiver chip and antenna circuit, enabling wireless communication with smart terminals (such as mobile phones, tablets, or dedicated monitoring equipment) using BLE (Bluetooth Low Energy) technology. The wireless transceiver chip is responsible for receiving and sending wireless signals, while the antenna circuit is responsible for transmitting and receiving signals.
[0037] Remote monitoring: When a smart terminal sends a query signal, the BLE radio frequency circuit on the tag receives the signal, processes it through the wireless transceiver chip, and returns a response, enabling remote monitoring and status query. This allows merchants or managers to understand the status and location of the product in real time.
[0038] Tamper alarm circuit: This circuit includes a series of components such as resistors and capacitors, as well as a pin connected to a solder point on the secondary board. When the tag is properly connected, the pin makes close contact with the solder point on the secondary board, forming a closed circuit.
[0039] Trigger mechanism: If the tag is illegally removed (i.e., the ejector pin separates from the sub-plate solder joint), the anti-tamper alarm circuit is activated. This voltage or current in the circuit changes, triggering an alarm signal from the wireless transceiver chip. The wireless transceiver chip then transmits the alarm information to the smart terminal via the BLE radio frequency circuit, alerting the merchant or management personnel.
[0040] Indicator light circuit: This circuit includes components such as resistors and light-emitting diodes, which are used to display the working status of the tag.
[0041] Status Display: Based on the signal received by the BLE radio frequency circuit or the trigger status of the anti-tamper alarm circuit, the indicator circuit controls the LED to display different colors or flashing patterns. For example, in standby mode, it may display a solid green light; in alarm mode, it may display a flashing red light. This allows users to intuitively understand the tag's operating status and the product's anti-theft status.
[0042] like Figure 6 As shown, when the utility model is working,
[0043] Normal working status:
[0044] BLE radio frequency communication: The anti-theft smart tag continuously broadcasts Bluetooth signals via the BLE radio frequency circuit. The Bluetooth gateway receives these signals and uploads them to the store management platform. Using electronic fence technology, the Bluetooth gateway receives the broadcast signal and monitors the signal strength to determine whether the product is within the pre-set safety zone.
[0045] RFID data comparison: At the same time, the RFID radio frequency circuit in the anti-theft smart tag communicates data with the RFID identification area, and accurately identifies the sales status of the product through radio data comparison.
[0046] Status indication and search: Store clerks can connect to the BLE radio frequency circuit through the mobile phone APP to drive the indicator light circuit to display the corresponding status, making it easy to quickly find products.
[0047] Normal product sales process:
[0048] RFID identification and payment: Goods with anti-theft smart tags first pass through the RFID identification area for data comparison, and payment is completed after confirmation.
[0049] Status Update and Unlock: The store clerk updates the product status on the store management platform and sends an unlock command to the anti-theft smart tag via the Bluetooth gateway, initiating the normal sales and unlocking process and disabling the alarm in the electronic fence area. The clerk then uses a special tool to disable the anti-tamper alarm, and the product can be sold normally.
[0050] Abnormal anti-theft behavior processing:
[0051] Tamper alarm triggering: If someone attempts to break the tamper alarm, the BLE radio frequency circuit will detect the interrupt signal and immediately broadcast the alarm data. After receiving the alarm data, the Bluetooth gateway feeds it back to the store operation platform area, driving the broadcast area to sound an alarm.
[0052] Abnormal RFID status: If a product passes through the RFID identification area but the store operation platform area does not receive the corresponding status update, the system will drive the broadcast area to issue a prompt sound to remind the store clerk to follow up with the product holder for further action.
[0053] Leaving the safe area alarm: When the anti-theft smart tag leaves the scanning area of the Bluetooth gateway, the Bluetooth gateway will immediately report to the store operation platform area and drive the broadcast area to sound an alarm to ensure that the goods are not illegally taken out of the safe area.
[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
