Bluezone helps saves resources to fight against Covid-19



If this app is deployed on a large scale enough, Bluezone will help save huge social resources and cost to fight Covid-19 epidemic in Vietnam, as well as help the economy resume operation under the new normal state.

Bluezone giúp tiết kiệm nhiều nguồn lực phòng chống Covid-19

According to the Department of Information Technology, Ministry of Information and Communications, on August 13, from 17 Covid-19 infection and suspected cases whose cell phones installed with the Bluezone application, Da Nang and Hanoi health authorities tracked 82 F1 and F2 cases who were not found out by the traditional way of investigating the patient’s schedule.

Although this number accounts for a small part of the total number of cases that need to be traced, the results show that Bluezone – a solution that uses Bluetooth connectivity to save contact history in the community – is really effective in preventing Covid-19 pandemic.

In theory, if the usage rate in the community reaches 60% or more, this application can help the society and the economy maintain operation even when the Covid-19 epidemic does not end yet. Because when most people have a sense of protecting themselves and the community, they will install Bluezone on their phones to receive early warnings if they accidentally get exposed to a case of F0 or F1. As a result, new Covid-19 cases are controlled for complete and accurate exposure history, so infection cases that are lost in the community will be phased out. People can communicate daily in society without having to worry too much about the risk of infection while the authorities do not have to apply anti-epidemic measures such as social distancing or lockdowns.

Bluezone helps to save Covid-19 fighting costs

Thanks to the application of Bluetooth technology to detect close contacts (below 2 meters) within the time of 15 minutes, Bluezone accurately traces people who have been exposed to suspected and infected cases (F0, F1). This technology is being deployed by many countries around the world to prevent Covid-19.

Previously, to identify people likely to be exposed to F0 cases, the authorities had to use zoning method through cell stations, and subscribers in the same cell with the F0 were counted as possible exposure. However, the accuracy of this measure is not high, with the zoning scope in urban area of 200m and 400m in the rural area, so the number of cases of wrongly identified of “being exposed to F0” is very high.

This technology was used in the last Covid-19 outbreak in Da Nang City. Accordingly, about 800,000 people were identified to be involved in the blockaded areas. In addition, about 1.4 million people were identified to visit Da Nang during this time, then going to other provinces. In the case of each person contacting 10 other people upon arrival home, there will be about 14 million people suspected of being infectious. This number makes many provinces have to isolate suspected people, conduct tests many times that is costly, time wasting.

With the ideal scenario, when everyone is using Bluezone, the tracing of contact history of F0 cases in Da Nang will be much more accurate. The number of suspected cases will also drop thousands of times, from 14 million possibly down to a few thousand. Provinces and cities will save huge resources mobilized for epidemiologic investigation, quarantine facilities, testing for tens of millions of people.

Maintaining social activities and the economy despite the Covid-19 pandemic

Not only helping to save huge resources and costs for epidemic prevention, if it is deployed widely enough, Bluezone also plays a role in helping to maintain social activities and the economy even when the Covid-19 epidemic is still underway.

If using the methods of zoning based on mobile networks as mentioned above, when the number of people suspected of being infected in a locality becomes too large, the only solution is impose lockdown measures. After 2-3 weeks, if the number of new cases does not break out and all sources of infection are screened, the locality will remove quarantine measures. However, this measure causes great damage when all socio-economic activities are delayed and people have to stay indoors.

Currently, Singapore is the most successful country in the world in implementing a Covid-19 prevention solution using Bluetooth technology, with more than 45% of the population installing an application called TraceTogether on their smartphones.

Similar to Bluezone, TraceTogether helps Singaporeans remember where they went and who they have been with in the last 25 days. If they have ever been in contact with another TraceTogether user who is identified as an infected or suspected case, they will be immediately alerted to minimize the possibility of unintentionally infecting relatives or friends. Thanks to this app, although there are still restrictions on the number of people gathered together, everyday life in Singapore is still quite normal.

If Vietnam can deploy Bluezone applications with a high rate of users like Singapore, we can completely think about the possibility of recovering tourism services in Da Nang, the economy resuming normal operations, the society operating under the new normal state safely, effectively preventing the Covid-19 epidemic. 

Bluezone is a Bluetooth-based app that helps determine if a person has come in contact with a COVID-19 patient,

The contract tracing app, developed by tech firm Bkav, uses Bluetooth Low Energy, a wireless personal area network technology, to link with smartphones within a two-meter distance.

If a user is positive for SARS-CoV-2 (known as person F0), health authorities can identify those who had close contact with that person (known as F1), and the system will alert them about the risk of infection.

They will be also provided with instructions on contacting health authorities for assistance.

The app is completely confidential, anonymous, and transparent, as it only stores data on the user’s phone and does not transfer user’s information or locations to the system.

Viet Nam’s fintech reaches new heights

Viet Nam’s fintech has reached new heights and the newly introduced regulatory sandbox is further fueling its growth.



The country’s fintech market is forecast to reach a staggering US$18 billion mark by 2024, according to an article on of Singapore.

Housing close to 200 fintech organizations, now 66 percent of adults have payment accounts as listed by the Ministry of Planning and Investment. The perfect medley of 91.3 million smartphone subscribers and an internet penetration rate of 73.2 percent have made the situation more conducive for the industry’s growth.

The success of these promising fintech organizations has been linked with their close ties with the banking sector that has created invaluable synergies.

The Viet Nam Banks Association (VNBA) has always been upfront in bringing favorable changes to the country’s financial services industry, be it for lowering SMS charges for banking services or urging Visa and Mastercard to reduce several types of fees on Vietnamese banks during COVID-19. 

Its most recent move got a lot of attention when it stepped forward as the official supporting partner for World Financial Innovation Series (WFIS) that’s shaping to be the country’s premier fintech event.

The National Digital Transformation Program by 2025, with an orientation towards 2030, which was approved in September 2021, sets the goal that 50 percent of banking operations by customers to be fully online. 

In addition, half of the population have a digital checking account while 70 percent of customer transactions made through digital channels. 

Besides, half of decisions on lending, small and consumer loans of individual customers made digitally and are automated whilst 70 percent of work and service records at credit institutions to be processed and stored digitally.

Digital banks attract significant numbers of customers

The number of new customers of commercial banks has increased dramatically in recent years thanks to their digital applications.



After only six months of launching MyVIB 2.0 digital banking application – which uses multi-cloud computing technology to process 60-70 per cent of the input data to help banks realise ideas, bring products and services to the market faster and respond sooner to customer requests, VIB has doubled the number of customers compared to the previous year and reach the target of 4 million customers nearly a year earlier than expected.

Not only VIB, the wave of “cloudisation” of digital banking applications to expand modes and storage capacity, and increase integrated processing and user data security capacity has been invested in and implemented by many commercial banks.

Currently, VietABank, PVcomBank, VietinBank, Techcombank, SeABank, ABBank and OCB have all integrated cloud computing technologies to launch new digital banking platforms serving the sales of retail products and services, attracting millions of users.

The business results by the end of 2022 of banks showed a sharp increase in the number of new customers attracted by banks thanks to their digital applications. For example, MB last year added 7 million customers in the wake of developing Biz MBBank and Charity app while Techcombank with E-Banking apps (using AWS cloud computing technology) attracted an additional 1.2 million users in 2022. ACB and TPBank also said they recorded an annual growth of 30 per cent in the number of customers using digital applications in the 2019-22 period.

Along with the increase in the number of customers, the investment in new technologies and digitalisation of business activities have helped many banks attain significant achievements. For VIB and ACB, the proportion of revenue from retail activities was around 90 per cent in 2022. Retail activities at other banks such as MB, Techcombank and Sacombank currently account for more than 50 per cent of their business portfolio.

Recent research by Gimigo Vietnam showed 2023 will continue to witness fierce competition between banks in developing retail digital banking applications to gain market share.

According to Gimigo, the group of large State-owned banks such as Vietcombank, BIDV, Agribank, VietinBank and MB was leading in the retail segment thanks to being trusted by users and having a widespread network by the end of 2022. However, the group of private banks such as Techcombank, Sacombank, ACB, VPBank and TPBank have significantly improved their awareness level and attracted a large number of users in recent months.

Gimigo’s survey in Ha Noi, HCM City and some other big cities showed the digital applications of Techcombank, ACB and Sacombank are currently competing strongly with large-sized State-owned banks. Other private banks such as TPBank and VPBank also have high net promoter scores (NPS). Thus, the group of banks has many opportunities to expand the customer base thanks to the existing group of loyal customers and the new customers.

According to experts, developing the networks of branches, transaction offices, POS and ATMs is no longer the banks’ top priority. Instead, they focus on digitisation of products and services. To maintain the number of customers, banks need to pay more attention to transaction costs, quality of products and services, staff attitude, customer service, and continuous improvement of online procedures.

Regarding the development trend of digital application generations this year, Gimigo said besides investment in cloud computing technologies and applying Artificial Intelligence (AI) and Machine Learning to develop applications to support retail sales of products and services, banks will tend to pour in an integrated open banking ecosystem.

Some banks, which have so far invested in purely digital banking models such as Cake, Timo, Tnex, Octo and Ubank, have attracted users. For example, VPBank’s Cake app currently has 1 million users.

Experts forecast banks will invest more in developing completely new digital banking brands in the near future. In which, micro products and services will be integrated into personal financial management tools to attract customers to use banks’ retail products and services.

Over 57,000 ransomware attacks hit Vietnam in 2022

Ransomware is targeting businesses throughout Southeast Asia.



Vietnam suffered 57,389 ransomware attacks in 2022, the third-highest in Southeast Asia following Indonesia and Thailand.

The region recorded a total of 340,904 ransomware attacks targeting businesses last year, General Manager of Kaspersky for Southeast Asia Yeo Siang Tiong told a press briefing in Ho Chi Minh City on March 14.

Ransomware is a type of malware that locks a computer and mobile device or encrypts electronic files. To obtain the “decryption” key or retrieve data, a ransom is sought by the cybercriminals behind the attack.

Digital kidnappers are targeting enterprises in Southeast Asia, Mr. Yeo said, and the trend is forecast to continue increasing this year and see more complicated attacks.
