No need to swipe the card, no need to swipe the code, just stretch out the palm of your hand, you can swipe the subway turnstile. This new mode of "brushing" convenience has now been realized on the Daxing Airport Line of the subway.
On the 10th, the reporter found at Caoqiao Station of the Daxing Airport Line of the subway that there were several new automatic ticket vending machines outside the entry gates. Unlike other ticket vending machines, the new ticket vending machine screen is larger, in addition to the normal operations such as ticket purchase, recharge, and online ticket collection, there is an option to "open a palm ride" on the page. At the bottom of the screen, there is also a circular palm recognition area, similar in size to a mobile phone wireless charger.
The reporter followed the guidance of the screen and tried to open the brush palm ride. First of all, you need to enter the palm print. When the palm is placed above the ring recognition area, the recognition area begins to flash red light, and when entering the palm print, it is necessary to constantly adjust the height of the palm. After completing the input, the device will sound a "beep" and the ring will turn green. Subsequently, a QR code appears on the screen, and passengers also need to complete the authorization of the agreement, real-name information authorization and open WeChat palm payment in the WeChat mini program. After completing all the processes, you can start the brush ride service.
With the opening of the brush palm ride, some gate passages have also increased the brush palm riding area. When riding the subway, passengers only need to find the brush palm gate with the ring sign, face the palm of the circle in the identification area, and start brushing. After the identification is complete, the ring turns green and the gate opens automatically. After exiting the country, the mobile phone will receive a reminder push for the deduction.
However, compared with the familiar card and code swiping gates, when passengers are new to the palm of the car, the time required for passengers to cross the gate may be slightly longer. The reporter tried many times to find that if the device failed to recognize the palm, the gate machine prompted the passengers to "stay farther" or "closer", and sometimes even needed to adjust the height of the palm many times to successfully complete the palm into the gate.
Like face recognition and fingerprint recognition, "brush palm" also belongs to a kind of biometric technology. However, compared with the first two biometric technologies, palm technology is still in the stage of only hearing its voice for most people.
The reporter noticed that when opening the brush palm ride, passengers need to agree to the "palm brush service instructions". It is mentioned that the service provider needs to collect, process and store palm information such as passengers' palm print information and palm vein information, which is used to build a palm information database and provide palm information comparison and verification. At the same time, the "Notice" also mentioned that service providers and cooperative technical service providers will not store original palm information samples and images. After completing the extraction of palm information elements, the service provider will delete the original palm information samples, images or anonymize them, unless otherwise provided by laws and regulations. In the process of use, the palm ride service only allows one person to bind one palm print information, and only supports residents over Chinese mainland age of 14. In addition, the current palm ride service only supports use within the Daxing Airport Line.
