Smart Eyes – CLi SmartEyes will help automate monitoring in public places, detect fever, and track epidemiological history without the need for personnel at checkpoints.
The device was developed by Associate Professor Dr. Pham Hong Quang from the Center for Informatics and Computing at the Vietnam Academy of Science and Technology, along with his team. A team of 20 engineers began researching the product in late 2020. After numerous tests and upgrades, the product was finalized and put into use by mid-August.
CLi-SmartEyes is designed to be compact, integrating an embedded computer with a camera, infrared temperature sensor, facial recognition software, and QR code functionality. The exterior features a display screen and a chip whistle to announce medical check results.

The device can be installed at the entrances of government agencies, businesses, industrial parks, hospitals, schools, bus and train stations, residential areas, etc., to monitor the epidemiological information of individuals entering and exiting.
To conduct a check, users need to follow 5 steps:
- Step 1: Stand in front of the device and raise your hand near the sensor to activate it.
- Step 2: Use the Bluezone or NCOVI application on your phone to scan the QR code displayed on the device.
- Step 3: Place your forehead about 4 cm away from the temperature sensor.
- Step 4: Position your face 30 cm away from the camera for the device to take a picture.
- Step 5: The result will be displayed on the screen.
Associate Professor Quang stated that the data collected by the device will connect directly to the portal of the Ministry of Health at qr.tokhaiyte.vn. Individuals who do not meet the health criteria will trigger an alarm, and the screen will display the reason (fever, high risk of disease, etc.).
CLi-SmartEyes also utilizes AI technology for facial recognition to detect any dishonest attempts to use someone else’s QR code for entry. The device is additionally equipped with a blood oxygen level sensor. To check, users simply need to place their finger on the sensor for a few seconds. Data regarding heart rate, breathing rate, and SPo2 levels will be displayed, and the system will automatically alert with sound and notes on the screen if there is a potential health issue, recommending individuals visit the nearest medical facility.
The device is also designed to integrate a contactless electronic token reader module containing a QR code to minimize entry control time in high-traffic areas.

Associate Professor Hong Quang mentioned that the system has been installed at the main lobby of building A1 at the Vietnam Academy of Science and Technology and at the entrance of the People’s Committee of Cua Dong Ward.
According to Mr. Quang, because it is domestically produced and technology-independent, the price is lower compared to imported products. Depending on the design and features, the price varies, but it is not more than 5 million VND per device.
Dr. Nguyen Phan Kien from the Institute of Electronics and Telecommunications at Hanoi University of Science and Technology evaluated that the system will enable quick medical monitoring without causing congestion during checks. “If the data connects to the national database, that would be excellent,” Mr. Kien stated.
However, Dr. Kien also pointed out a major issue with QR codes, which is their lack of security. The accuracy of infrared temperature measurement depends on the distance, background thermal noise, and the surrounding environment. “If all blind spots can be eliminated, this system definitely has the potential for widespread implementation,” Dr. Kien concluded.
