Description

Technical Field

[0001] This utility model relates to the field of radio frequency identification technology, specifically to an electronic paper screen stereo antenna radio frequency card. Background Technology

[0002] There are many types of cards used for information indication, such as airline boarding passes, baggage tags, exhibition cards, and train tickets. These cards are mostly paper tickets, which have various defects.

[0003] 1. Defects of paper airline boarding passes

[0004] ① Paper boarding passes require airport staff to operate barcode scanners to identify information, which is labor-intensive and inefficient.

[0005] ② Paper boarding passes require barcode scanning, which has a very short recognition distance, making it impossible to identify and locate passengers over long distances.

[0006] ③ Paper boarding passes cannot establish a passenger location database in the waiting area, affecting the efficiency of air service:

[0007] A) Unable to determine the location of passengers who have not boarded, the only option is to broadcast announcements urging them to register quickly. The announcements searching for passengers become noise in the waiting area.

[0008] B) The information of passengers who have given up boarding can only be confirmed after the passenger boarding process is completed. At this time, the luggage of the passengers who have given up boarding needs to be retrieved from the cabin, which takes a long time and often causes flight delays.

[0009] C) The airport waiting area is very large, making it impossible to pinpoint the location of a specific passenger, which affects the efficiency of security work.

[0010] 2. The shortcomings of traditional paper-based RFID baggage tags

[0011] ① A professional RFID printer must be used to print baggage tags. Passengers can only check in their baggage at the airport check-in counter or print baggage tags at the self-service baggage tag printer before checking in their baggage at the check-in counter.

[0012] A) This is the main reason for the long queues at check-in counters, a persistent problem affecting the quality of air service.

[0013] B) Airport airlines require a large number of check-in staff, which increases aviation operating costs.

[0014] C) The current paper baggage tags require check-in counters, space, and investment, which restricts the improvement of airport economic efficiency.

[0015] ② The reading distance of paper RFID baggage tags is about 7 meters, which can only meet the needs of RFID identification at baggage handling points and cannot meet the needs of long-distance RFID positioning beyond 15 meters. For example, automatic baggage loading identification, automatic baggage identification and positioning at baggage claim carousels, and baggage identification and positioning in the baggage hall cannot determine information such as the time when each piece of baggage left the baggage hall.

[0016] ③ The chip memory of paper RFID baggage tags is only 512 bit, which is insufficient to write information such as the delivery address and recipient's phone number for high-end passenger baggage handling.

[0017] ④ Paper RFID baggage tags do not have anti-metal properties. When attached to metal suitcases, the RFID sensitivity drops significantly, and the baggage sorting line often cannot perform RFID identification normally.

[0018] ⑤ Traditional paper luggage tags cannot establish a database for full-process luggage tracking, and cannot provide efficient and low-cost full-process tracking services.

[0019] 3. The shortcomings of traditional exhibition "RF exhibitor cards" and "RF visitor cards"

[0020] ① Visitors need to go to the exhibition hall to apply for individual visitor passes, which takes time to queue and requires a huge investment of manpower from the exhibition organizers.

[0021] ② Exhibitors can only obtain information about visitors by asking for postcards, but many people don't have business cards these days. Asking visitors for their WeChat IDs is also not very effective and greatly affects the exhibitors' gains.

[0022] ③ Due to the high water content of the human body and its absorption characteristics of radio frequency field energy, the reading distance of radio frequency cards attached to the human body is greatly attenuated. Traditional exhibition exhibitor cards cannot implement long-distance radio frequency identification and positioning, and cannot establish a database for the identification and positioning of personnel in the exhibition area.

[0023] ④ Without a database for identifying and locating personnel within the exhibition area, it is impossible to know the personnel density in each exhibition area in a timely manner, and it is impossible to quickly identify the location of specific personnel, which affects the level of security work in the exhibition hall.

[0024] 4. Disadvantages of paper train tickets

[0025] ① Paper train tickets must be printed at the train station by a specific printer. Even if a train ticket is purchased online, passengers must still go to the train station ticket office to pick it up, which is inconvenient for passengers. Train stations also need to be equipped with printers and staff, resulting in low work efficiency and high operating costs.

[0026] ② Paper train tickets rely on manual identification, punching, and inspection, which is labor-intensive and inefficient.

[0027] ③ Paper train tickets are manually visually identified, which makes it impossible to establish a dynamic passenger database and provide passengers with full-process tracking services, thus affecting the quality of railway operation services.

[0028] ④ Without a dynamic database of passenger information and without passenger density at a certain location, it is impossible to adjust the distribution of people in a timely manner and quickly determine the location of specific passengers, which affects security services.

[0029] ⑤ Paper train tickets have low anti-counterfeiting technology, making it possible for counterfeit tickets to appear and difficult to prevent illegal resale.

[0030] 5. Defects of traditional electronic paper screen RFID cards

[0031] To overcome the shortcomings of paper cards, cards that use radio frequency (RFID) technology for information recognition were developed. Traditional RFID cards have the following drawbacks:

[0032] ① The back of the electronic paper screen is a metal plating layer, which strongly absorbs the energy of the radio frequency field, resulting in a decrease in the reading sensitivity of traditional RFID tags. The position of the RFID tag of the traditional electronic paper screen RFID card can only be offset from the position of the electronic paper screen to reduce the influence of the metal plating layer of the electronic paper screen on the RFID tag. The radio frequency reading distance is less than 7 meters, and long-distance radio frequency identification and positioning cannot be implemented.

[0033] ② The radio frequency identification distance of traditional electronic paper RFID cards is affected and reduced against metal or human backgrounds, so they cannot be installed on metal suitcases or used on boarding passes, visitor cards, or various ticket cards that are carried by the person.

[0034] ③ The RFID tag of traditional electronic paper screen RFID cards does not coincide with the electronic paper screen, resulting in a wider and larger size of the electronic paper RFID card. This not only affects the appearance, but also makes it difficult to attach, which may cause more collisions and affect the hanging safety of the RFID card.

[0035] ④ Traditional electronic paper screen RFID tags have attachment holes on the edge of the RFID tag. When used as airline baggage tags, the RFID baggage tags are prone to flipping when attached to the luggage handle, causing the electronic paper screen to face down. During baggage sorting, it is impossible to photograph or recognize the barcode and text on the electronic paper screen, resulting in baggage without baggage barcode information and causing errors in baggage operations. Utility Model Content

[0036] In order to overcome the shortcomings of existing technologies, this utility model provides an electronic paper screen stereo antenna radio frequency card.

[0037] The technical solution of this utility model is as follows:

[0052] The RF chip is a semi-active RF chip, capable of both passive and long-range identification via power-on UHF RF chips. The storage space of the semi-active RF chip ranges from 2Kbt to 8Kbt, which is 4 to 16 times higher than the 512bt memory of traditional UHF RFID chips, providing significantly stronger information storage capabilities.

[0053] (8) Radio frequency antenna

[0054] The radio frequency antenna is a coiled inductor antenna with aluminum foil at the top and bottom, so that the metal plate and the aluminum foil come into contact to form part of the three-dimensional antenna.

[0055] (9) Low-light photovoltaic cells

[0056] Low-light photovoltaic cells can power radio frequency chips in the presence of indoor light sources, thereby increasing the range of radio frequency identification.

[0057] (10) Power Manager

[0058] The electronic paper-screen stereo antenna RFID card has no battery, making it suitable for the safety requirements of aviation operations. The electronic paper-screen stereo antenna RFID card has three power supply methods:

[0059] The power manager is connected to the low-light photovoltaic cell and is used to obtain electrical energy from the low-light photovoltaic cell.

[0060] The power manager is connected to the NFC module assembly in the communication module, and is used to obtain power from the smart terminal through the NFC module assembly.

[0061] The power manager connects to the external power supply's waterproof contacts. When Bluetooth is active, it draws power from the operating power source through the external power supply's waterproof contacts.

[0062] (11) Waterproof contacts for external power supply

[0063] The external power supply waterproof contacts are magnetic, allowing the power supply to be connected in Bluetooth working mode.

[0064] According to the above-described solution, the beneficial effects of this utility model are that the electronic paper screen stereo antenna radio frequency card of this utility model can replace traditional paper tickets, and it can also facilitate user operation, improve production efficiency, reduce the number of operating personnel in airports, stations, stadiums and other places, and reduce operating costs.

[0065] The electronic paper screen stereo antenna RFID card can also improve the recognition distance and realize the long-distance positioning of users. It can accurately locate users in places such as aviation, exhibitions, and road operations, thereby improving operational efficiency.

[0066] When this utility model is attached to luggage or worn on a person, it is more aesthetically pleasing and does not affect information recognition, thus avoiding operational errors. Attached Figure Description

[0141] ⑥ Radio frequency identification when installed on metal suitcases or packaging.

[0142] Industry applications of RFID cards with stereo antennas for electronic paper displays:

[0143] 1. Application and characteristics of "electronic paper screen stereo antenna RFID card" in the aviation industry

[0144] (1) such as Figure 3-1 As shown, users can create their own electronic paper-screen stereo antenna RF boarding pass at home. The creation process includes:

[0145] ① First, the user brings their mobile phone close to the "electronic paper screen stereo antenna RFID card," activates NFC or Bluetooth to connect with the card, and then logs into the airline's website, enters their identification number, and completes the registration information verification. ② Second, after confirming the passenger information, the airline's website proceeds to the check-in process: the airline's website uses the mobile phone or other device to control the "electronic paper screen stereo antenna RFID boarding pass," displaying the information and text of a traditional boarding pass on the electronic paper screen and writing the corresponding information into the RFID chip. After reviewing the information, the passenger's mobile phone responds to the airline's website, completing the registration and production of the "electronic paper screen stereo antenna RFID boarding pass." ③ Then, at the airport, the user bypasses the check-in counter and directly enters the fast lane. The RFID reader at the lane automatically reads the chip information of the "electronic paper screen stereo antenna RFID boarding pass," and after check-in, the passenger enters the airport's waiting area. The passenger identification and positioning RFID reader in the waiting area automatically inputs each passenger's information into the data center, and the airport ground service department provides personalized service to each passenger. ④ Finally, the RFID reader at the cabin door entrance reads the information on each "electronic paper-screen stereo antenna RFID boarding pass" and automatically counts the number of boarding passengers. This allows for the quick identification of the names and locations of passengers who have not yet boarded, enabling timely notification and minimizing flight delays.

[0146] like Figure 3-2 As shown, the application features of the electronic paper screen stereo antenna RF boarding pass include:

[0147] ① Users can check in at home, replacing the traditional check-in counter, saving airports and airlines a lot of staff.

[0148] ② Users do not need to queue for check-in at the airport; they can enter the waiting area through the express check-in lane and enjoy a relaxed and fast travel experience.

[0149] ③ The electronic paper screen stereo antenna RFID boarding pass overcomes the influence of the human body on the RFID distance. The RFID device in the waiting area can record the location of passengers within a 25-meter radius. The airport ground service department can provide personalized services to passengers. For example, it can quickly find passengers who have not boarded and help them board. If passengers who have not boarded are not in the waiting area, the passenger abandonment case procedure can be implemented to reduce flight delays.

[0150] ④ The RFID card reader at the cabin door node automatically reads the chip information of the electronic paper screen stereo antenna RFID boarding pass, automatically counts the number of boarding passengers, and automatically displays the information of passengers who have not boarded, reducing the workload of flight attendants.

[0151] ⑤ The ground service data center records the location of each passenger in the waiting area, which helps to improve security management.

[0152] (2) such as Figure 4-1 As shown, users can create their own electronic paper screen 3D antenna RF luggage tag at home. The creation process includes:

[0153] The airline's website inquires whether passengers have checked baggage. Passengers respond via mobile phone that they have checked baggage and bring an unactivated "electronic paper screen 3D antenna RFID card" close to their phone to initiate the "electronic paper screen 3D antenna RFID baggage tag" creation process. Passengers then provide baggage details to the airline's website, such as "fragile baggage," "delivery destination and contact number after baggage arrival," etc. The airline's website, controlled by the passenger's mobile phone, displays the traditional baggage tag's graphic and text information on the electronic paper screen of the "electronic paper screen 3D antenna RFID baggage tag." Simultaneously, it writes the passenger's phone number, flight information, baggage delivery destination, and contact number into the chip of the "electronic paper screen 3D antenna RFID baggage tag," completing the creation and registration of the electronic paper screen 3D antenna RFID baggage tag.

[0154] like Figure 4-2 , Figure 4-3 As shown, the application characteristics of the electronic paper screen stereo antenna radio frequency luggage tag include:

[0155] ① Users can obtain baggage tags at home, replacing the traditional check-in counter process, saving airports and airlines a significant amount of staff and reducing their operating costs.

[0156] ② Users can use the fast lane to check in their luggage and enjoy a relaxed and fast air travel experience.

[0157] ③ The electronic paper screen stereo antenna RF luggage tag has anti-metal function and can be attached to aluminum alloy suitcases without affecting the RF identification effect during luggage sorting.

[0158] ④ The chip memory of the electronic paper screen stereo antenna RFID baggage tag is greater than 2Kbt, which is more than 4 times the 512dt memory of the traditional RFID baggage tag chip. It can write more information, thus becoming a full-information RFID baggage tag. It implements a front-end baggage information processing system without the need for back-end data center support. At each process node (such as baggage check-in, baggage handling, baggage loading into small containers, baggage loading onto the plane, baggage unloading, baggage leaving the baggage claim hall, baggage delivery after arrival, and hotel confirmation of receipt of baggage), information can be obtained from the chip of the "electronic paper screen stereo antenna RFID baggage tag", and passengers can be contacted in a timely manner by phone to provide efficient and personalized service.

[0159] ⑤ It helps build a data center for the full-process identification and positioning of departing baggage, ensuring error-free departure baggage operations.

[0160] ⑥ It helps build a data center for the full-process identification and positioning of arriving baggage, ensuring error-free operation of arriving baggage.

[0161] ⑦ The large memory function of the electronic paper screen stereo antenna radio frequency baggage tag helps to improve the space and efficiency of aviation services.

[0162] 2. Applications and characteristics of "electronic paper screen stereo antenna RFID card" in the exhibition industry

[0163] (1) such as Figure 5-1 As shown, users create their own electronic paper screen stereo antenna RF exhibition card. The creation process includes:

[0164] First, exhibitors connect their mobile phones to the "electronic paper screen stereo antenna RFID card" via Bluetooth at home. They then log in to the exhibition's official website, entering their company name, ID number, phone number, and photo as required to apply for an exhibitor card and register.
