HTV9 News reports on Smarttech's IoT Data Management platform and LogTag devices at Vietfish 2026. Smart solutions – Elevating the Vietnamese seafood industry.
The VIETFISH 2026 International Fisheries Exhibition has concluded, providing SMARTTECH with valuable encounters and profound real-world insights from the seafood industry—and, above all, the opportunity to hear firsthand the needs of businesses across the supply chain.
During transportation and export, a single incident involving temperature, light, or impact can compromise product quality, thereby affecting the company's reputation and logistics costs.
In the retail, cold storage, and food processing industries, even a small temperature deviation can significantly impact product quality and brand reputation.
SMARTTECH's temperature and humidity monitoring solution helps businesses proactively control storage conditions, automatically store and retrieve data, reduce manual operations, minimize product risks, and support compliance requirements in cold storage, pharmaceutical warehouses, and laboratories.
Smarttech is proud to contribute to building a safer and healthier Vietnam through reliable cold chain monitoring solutions. We believe that technology is only truly valuable when it becomes a reliable guarantee of human safety.
In the cold chain supply, cut flowers are one of the most sensitive items. Just one unfavorable journey or a sudden change in environment is enough to severely degrade product quality, leading to a high rate of complaints and directly impacting reputation.
