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.

Following the P30 series, Huawei announced the rollout of HarmonyOS 3 first beta for the Mate 20 series. This is a major development for this old flagship lineup as it will now get a brand-new software ecosystem with major improvements.
Huawei is rolling out HarmonyOS 3 beta for Mate 20 series with firmware version 3.0.0.73. It is noted, this rollout is out for the users who participated in the first batch of beta activity.
However, you should also remember that Huawei is sending this beta build gradually among the eligible device owners. Below you can check the Mate 20 models:
- Mate 20 (HMA-AL00)
- Mate 20 (HMA-TL00)
- Mate 20 Pro (LYA-AL00, LYA-AL10)
- Mate 20 Pro (LYA-TL00)
- Mate 20 RS (LYA-AL00P)
- Mate 20 X（4G） (EVR-AL00)
- Mate 20 X（4G） (EVR-TL00)
Closed beta:
The latest rollout comes under the closed beta label and it’ll be followed by public beta after a round of beta OTA software tests. Meanwhile, the stable release may take some time to release among Huawei Mate 20 series users.
Huawei Mate 20 is currently divided into global and Chinese versions. The Chinese version runs HarmonyOS 2 operating system, which was upgraded from EMUI 11. On the other hand, the global version of these models runs EMUI 12.
But the new HarmonyOS 3 upgrade will allow the owners of this flagship to experience a brand feature set.
HarmonyOS 3 beta notes:
- Due to version restrictions, you are required to upgrade to version 2.0.0.270 first, otherwise, you will not receive the latest beta version.
- During the closed beta testing, you have to enable the user experience improvement plan switch (path: Settings-System and Update-User Experience Improvement Plan), which would help the Huawei software team to conduct system and app analysis, fault diagnosis, etc., and continuously improve the quality of the version.
- This update will not delete your data, but it is still recommended that you back up all important data to your PC or cloud before upgrading. Also, confirm that the backup content is complete and valid, otherwise, there may be a risk of data loss.
- Because some third-party applications may not be compatible with HarmonyOS, the third-party application may not work properly after the update. It is recommended that you try to update the apps to the latest version in Huawei AppGallery.
- After the upgrade is complete, the phone may experience heat, lag, or slow charging. This is caused by some self-optimization and adaptation actions performed by the system after the upgrade. Please rest assured that it will recover by itself after a period of time. It is recommended that you charge for 1 hour in your spare time. During the charging period, the system will optimize once to ensure that the mobile phone application is quickly adapted.
- This update needs 8GB of free space, and the installation package will be automatically deleted after the update without taking up storage space.
