Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency identification (RFID), and more specifically to an RFID tag card making device. Background Art

[0002] In the field of smart door locks and access control systems, although there are now more convenient and fast unlocking methods such as Bluetooth, fingerprint, and facial recognition, in the hotel field, because most guests stay temporarily and need to delete their personal information after checking out, most hotels still use traditional physical cards to check in out of the guests' wishes and the need to protect their personal privacy. Usually, a room card will be issued at the hotel front desk when checking in, and the room card can be used to take the elevator, enter the room, restaurant, gym, etc.

[0003] The current card making process mainly includes: using a card to swipe the offline door lock, the offline door lock writes the door lock's adaptation information to the card, and then taking the card with the adaptation information back to the hotel front desk, placing the card on the card maker, the card maker reads the adaptation information stored in the card and uploads the adaptation information to the host computer (computer), and the card making software on the computer writes the unlocking information and unlocking authority to the card to be written according to the received offline door lock adaptation information.

[0004] In addition, when the working record of the offline door lock needs to be retrieved, it is also necessary to swipe the card on the offline door lock. The offline door lock writes the working record information of the door lock to the card, and then takes the card with the adaptation information back to the hotel front desk. The card is placed on the card maker, and the card maker reads the working record information stored on the card and uploads the working record information to the host computer.

[0005] It can be seen that under the existing conditions, when you want to configure the card making information for a new offline door lock in the host computer and read the working record information of the offline door lock, you must rely on the card as an intermediate medium to obtain relevant information from the offline door lock. The workflow is cumbersome and inconvenient. In addition, the memory of the card is often small and cannot store too much information. When reading the working record information of the offline door lock, there will also be a problem of insufficient memory.

[0006] In view of the above situation, some existing solutions are to use a dedicated handheld device to simulate a card to read door opening records and other information. However, the cost of the handheld device is relatively high, and after reading the information fed back by the offline door lock, the information still needs to be imported into the host computer, which is cumbersome and increases costs.

[0007] Therefore, how to provide an RFID tag card maker that can simulate a card to simplify the process of making a room card and reading offline door lock work record information has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0012] The information interaction unit can establish information interaction with the host computer;

[0013] The card reader / writer unit is used to read the information stored in the RFID tag card and write information to the RFID tag card;

[0014] The simulated card unit is used to simulate a virtual card and read and store information stored in an offline device;

[0015] The simulation card unit can store the information read from the offline device into the storage module.
