Description

Technical Field

[0001] This utility model relates to the field of RFID destruction equipment technology, and in particular to a device that can destroy RFID tags using management software. Background Technology

[0002] Radio Frequency Identification (RFID) technology, as a non-contact automatic identification technology, has been widely used in access control, personnel attendance, and asset tracking due to its advantages such as fast identification speed, high accuracy, and strong anti-interference capabilities. In access control systems, RFID cards or key fobs serve as the primary carriers of personnel identity, and the security of their management directly affects the security level of the controlled area. When an employee leaves or a visitor departs, the human resources department or front desk staff manually retrieves their physical RFID card and then notifies the security or IT department via telephone, email, or internal work order system. The corresponding UID or permissions are then logically deactivated in the access control system management software's backend. For cards deemed obsolete, some organizations with high security requirements physically destroy them, collecting the recovered cards and periodically using specialized high-powered shredders, hole punchers, or strong magnetic fields to physically destroy them. However, in existing technologies, there is a significant time window between the physical card being retrieved and the backend system's permissions being deactivated. During this period, the retrieved RFID card remains logically valid, and if maliciously misused, it will pose a serious threat to the area's security. Even if the card is recycled and deactivated in the system, the physical card itself remains unchanged. The data such as the UID stored in the card can still be read by a standard RFID reader. Although the above methods can physically solve the card reuse problem, the equipment is bulky, the process is complex, and the cost is high. Moreover, it is a post-event processing method; it cannot be integrated into the access control point and cannot achieve immediate secure processing of return and cancellation. In addition, strong physical destruction methods such as high-voltage pulses will completely damage the card structure, which is not conducive to environmentally friendly recycling. Utility Model Content

Through various structural improvements, the RFID destruction mechanism is integrated into the access control gate. Utilizing the existing operating system, RFID cards are read and written, allowing for the destruction and recycling of RFID cards before departing employees leave the access control area, thus improving management efficiency. This improved software-based RFID destruction device uses standard RFID protocols for card writing and integrates with existing access control software and database logic. The destruction process is simply a card rewriting.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] See Figures 1 to 5 The device provided in this embodiment, which can destroy RFID tags using management software, includes: an access control wing gate 1, an identification unit 2, and an RFID destruction mechanism 3; the identification unit 2 and the RFID destruction mechanism 3 are electrically connected.

[0029] The access control wing gate 1 includes an isolation plate 11 and a movable wing gate plate 12, used to control personnel passage;

[0030] The identity recognition unit 2 is installed on the access control wing gate 1 and is used to verify the user's identity. It includes a face recognition camera 21, a display screen 22 and an RFID card reader area 23.

[0031] The RFID destruction mechanism 3 is installed on the access control wing gate 1. The RFID destruction mechanism 3 includes: an RFID card reader / writer 32 and an RFID card reader / writer motherboard 33, used to read and write the UID information of the RFID card 30; an RFID card 30, an RFID card or tag containing UID information; a control switch 34, serving as the on / off actuator for the high-voltage circuit; and an RFID card recycling slot 36 for inserting the destroyed RFID card 30. An indicator light 35 is used to display the working status of the destruction mechanism, including standby, destruction in progress, destruction successful, and fault. The indicator light 35 is a multi-color LED indicator.

[0032] Preferably, the RFID reader / writer motherboard 33 is equipped with an MCU331, which serves as the main control chip;

[0033] Preferably, the MCU331 model is STM32F103C8T6;

[0034] It also includes an RFID radio frequency module 332, which communicates with the RFID card 30 to complete card reading or writing;

[0035] Preferably, the RFID radio frequency module 332 is model MFRC522; RC522 is a core component widely used in contactless RFID systems. This module is based on the MFRC522 chip, which is a highly integrated UHF RFID reader or writer solution that can support ISO14443A standard cards and tags.

[0036] The MFRC-522 chip operates at a voltage of 3.3V, a current of 13-26mA, and a frequency of 13.56MHz. The RFID radio frequency module 332 is connected to an RFID antenna.

[0037] Preferably, the Bluetooth module 333 is used to wirelessly communicate with the existing access control management software on the PC host 4, receive card writing instructions, and report status.

[0038] Preferably, the Bluetooth module 333 is HC-05;

[0039] Preferably, the communication interface 334 is a wired communication interface, and the communication interface 334 is electrically connected to the MCU 331.

[0040] Preferably, the PC host 4 runs existing access control management software for processing identity information, reading and searching RFID UID information, and transmitting and issuing RFID card writing instructions.

[0041] See Figures 1 to 5 In this embodiment, the PC host 4 is connected to the identity recognition unit 2 and the RFID destruction mechanism 3 via wired or Bluetooth protocol. When connected via wired, the communication interface 334 protocol is one of UART, SPI, or I2C. When connected via Bluetooth protocol, it can connect not only to the PC host 4 but also to a mobile APP, etc., so that on-site personnel can connect and read or write cards according to actual needs.

[0042] See Figures 1 to 5In this embodiment, when the device is working, the RFID card and associated facial information of the departing employee are marked as abnormal by the connected existing technology management software. When the departing employee swipes their RFID card or leaves the access control system, the access control system cannot open. The departing employee needs to place the RFID card on the RFID reader / writer 32 of the RFID destruction mechanism 3. The RFID reader / writer 32 reads the information and transmits it to the PC host 4. After the departing employee presses the control switch 34, the existing technology management software is triggered to automatically write the card, or relevant personnel can remotely operate the existing technology management software to swipe the information on the RFID card 31. The UID of the RFID card 31 after swiping is set to a preset value. When the RFID card 31 is swiped again, it will be an invalid card, preventing the leakage of the UID value in the RFID card 31. After successful swiping, the RFID destruction mechanism prompts the user to complete the operation through the indicator light 35 or voice prompt, and puts the RFID card 31 into the RFID card recycling slot 36 to realize the recycling of the RFID card 31. After the RFID card 31 is recycled, relevant personnel can remotely open the wing gate 12 of the access control system, and the departing employee can leave.

[0043] This application describes a device that uses management software to destroy RFID tags. Under confidentiality, it has been applied on a small scale in a high-tech R&D park, achieving a secure closed loop from system access cancellation to immediate physical credential invalidation, preventing the risk of reusing departing employees' cards. Processing efficiency is improved by integrating card collection, cancellation, and auditing into a self-service operation at the access control point, enhancing management efficiency and reducing manual intervention by HR and security departments. Each destruction is meticulously recorded electronically, meeting the company's internal security and compliance audit requirements. Cards destroyed by the software retain their physical structure and are collected uniformly by the park, then handed over to the card supplier for data erasure and reinitialization, achieving resource recycling and aligning with environmental protection principles. The park has thousands of employees, and its access control system widely uses RFID employee cards. Park security regulations require employees to return their access cards upon leaving the company. However, traditional processes have loopholes: some departing employees may falsely claim their cards are lost but actually retain them, or returned cards may not be promptly deactivated in the system backend, leading to the risk of these cards being copied or misused, posing a potential threat to the park's physical security.

[0044] In the current process, departing employees complete the formalities at the HR department, then HR collects the physical access card, and finally, HR notifies the security department to cancel the card's access in the back-end system. This process carries several risks: time lag risks, as there is a delay between card collection and system cancellation, during which the card can still be used; management is separated, with HR responsible for card collection and IT or security responsible for system cancellation, potentially leading to communication errors or omissions; card status is uncertain, as collected cards are not immediately physically invalidated, and if stolen by internal personnel, their UID can still be read and copied using technical means; and the process is cumbersome, requiring departing employees to complete multiple procedures at HR and the exit access control point.

[0045] The new process for destroying RFID devices using the management software of this utility model is implemented in the park. The RFID destruction mechanism of this utility model is integrated into the access control wing gates at the main entrances and exits. The specific application steps are as follows: When an employee leaves the company, after the employee "Zhang San" completes the resignation procedures in the HR department, his employee card and associated facial information are marked as "resignation pending recycling" in the access control management software in real time. Therefore, his passage is blocked. Zhang San walks to the exit wing gate and swipes his card or facial recognition as usual. After the identity recognition unit 2 recognizes his information, the access control management software running on the PC host 4 determines that his status is abnormal. The wing gate 12 remains closed, and the display screen 22 prompts: "Your access card is pending recycling and cancellation. Please use the destruction and recycling machine on the right." When the card is destroyed, Zhang San, following the instructions, walks to the wing gate integrated with the RFID destruction mechanism 3. He places his RFID card 30 in the sensing area of ​​the RFID reader / writer 32. The reader / writer reads the card's UID and reports it to the PC host 4 via Bluetooth module 333 or communication interface 334. The access control management software running on the PC host 4 reconfirms that the card is in the "awaiting recycling" state and prepares the card writing command. Zhang San presses the control switch 34, and the MCU 331 receives the trigger signal, sending a specific card writing command to the RFID card 30 via the RFID radio frequency module 332. This command rewrites the key permission data in the card's sector to a fixed, meaningless invalid value or a specific discard code. Status feedback and recycling: After the destruction operation is completed, the multi-color LED indicator 35 changes from standby blue to solid green, displaying "Destruction successful". Zhang San, following the prompts, puts the expired RFID card into the RFID card recycling slot 36 to complete the physical recycling. The audit log was completed and the passage was released. At the same time, the management software on PC host 4 automatically generated an unalterable audit log, which included the following information: "Operation time: 2024-10-27 15:30:05; Operator: Zhang San ID: EMP10086; Destroy card UID: 0x89A5B211; Result: Success"; The security center received a notification of the operation completion in real time; The management software remotely controlled the wing gate, and wing gate 12 opened, allowing Zhang San to leave smoothly. The entire process was completed within 5 minutes.

[0046] In summary, the above embodiments of this utility model, through various structural improvements, integrate the RFID destruction mechanism into the access control wing gate. Utilizing the existing operating system, RFID card reading and writing are achieved, enabling the destruction and recycling of RFID cards before departing employees leave the access control area, thus improving management efficiency. The improved RFID destruction device using management software utilizes standard RFID protocols for card writing and integrates with existing access control management software and database logic. The destruction action is simply a rewriting of the card. Compared to traditional high-voltage pulse destruction, software destruction preserves the physical structure of the RFID card; the chip and antenna are not damaged. Although the function is disabled, the card can be more easily recycled and reused. This application achieves a secure closed loop from system permission cancellation to immediate physical credential expiration, avoiding the risk of reusing employee departure cards; it improves processing efficiency by integrating card collection, cancellation, and auditing into a self-service operation at the access control point, enhancing management efficiency and reducing manual intervention by HR and security departments; each destruction is recorded electronically, meeting the company's internal security and compliance audit requirements; cards destroyed by the software retain their physical structure and are collected uniformly by the park, then handed over to the card supplier for data erasure and reinitialization, achieving resource recycling and conforming to environmental protection principles.
