Open source HarmonyOS adds support for ZT925 payment device
Zhengtong Electronics has made a financial payment scenario and launched a payment password keyboard device ZT925 equipped with OpenHarmony, the open-source HarmonyOS operating system.
According to the information, Huawei and OpenAtom foundation are working together to increase industry partners to adopt the open-source HarmonyOS named OpenHarmony.
The ZT925 payment device has also passed the OpenHarmony 3.1 Release version compatibility evaluation and received the OpenHarmony ecosystem product compatibility certificate.
Adding to this, the device can be equipped with different forms of master devices by applying OpenHarmony’s distributed soft bus technology, so as to adapt to different application scenarios.
The ZT925 electronic payment device integrates financial components such as a password keyboard and a contactless card reader to form a minimal secure payment suite that provides financial payment functions externally.
With OpenHarmony 3.1 Release version, the device has its own distributed networking capabilities. It can automatically discover and complete identity authentication and automatic networking with the main device and expand the financial payment feature of the main device.
After the ZT925 and the main device are powered on respectively, they form a star-shaped network with a stable topology according to their respective preset policies.
The user handles the business on the main device and transfers the transaction information to the ZT925 through the OpenHarmony soft bus technology in the financial payment transaction link. The indicator light of the remote terminal ZT925 starts to flash and enters the state of financial business processing, responding to the customer’s card swiping and password input on the ZT925.
So far, the main device and ZT925 have completed the payment transaction through the remote linking process. This time, the terminal product makes payment-related security components and general components into independent components, so that the terminal form fits better with the scene and improves the overall portability.
The terminal equipment manufacturers further divide labor, professional security payment manufacturers focus on the development of security components, industry manufacturers focus on general components and business experience, and aggregate different security components through specified strategies to form a super terminal on the merchant side. This contributes to Improving the payment experience and security.
More importantly, for the update of the mainline version of the terminal operating system, the terminals interconnected through the OpenHarmony soft bus only need to do differentiated security certification to quickly iterate industry equipment.
Traditional financial terminals use core boards and extended backplanes to assemble security components such as PIN pads and common components such as display screens and cameras, which cannot well meet the fragmented needs of the industry.
If the scenario needs to add a display screen, it will involve the change of the whole machine. Now, financial components such as PIN pads and card readers are made into independent payment security suites, and the financial part is decoupled.
The OpenHarmony soft bus technology is equipped with different forms of the main equipment to jointly carry and display financial services and help the development of financial services.
OpenHarmony soft bus technology on financial terminals, Zhengtong Electronics starts from the practicality, reliability, security, and scalability of financial terminals, improves the business support capabilities and intelligence level of financial terminals, and meets the needs of fragmented industries.
Furthermore, Zhengtong Electronics has enriched the OpenHarmony soft bus control technology by introducing customized networking strategies to improve the efficiency of financial terminal reconstruction.
