Six decades on, Casio is not just a global brand but a silent companion to millions of students, scholars, businessmen, and workers worldwide.
In Vietnam, this journey continues with the companionship of Binh Tay Import-Export Joint Stock Company (BITEX) – the pioneer in bringing Casio calculators to the market since 1993. For over 32 years, BITEX has tirelessly turned Casio calculators from an unfamiliar product into a familiar companion in almost every Vietnamese student’s backpack. They have also contributed to shaping a generation that learns more effectively, logically, and is better prepared for the digital age.
From Japan to Vietnam: A Journey of Sustainable Values
When Casio introduced its first pocket calculator in 1965, few could have imagined that this compact device would become synonymous with accuracy, efficiency, and relentless innovation. Over the decades, through research and improvement, Casio has expanded its global influence, reaching far beyond Japan’s borders to become a leading brand in electronic calculators.

The pocket-sized calculator is a trusted “colleague” for small business owners.
In Vietnam, the journey of spreading these values began in the early 90s. Against the backdrop of an evolving education system, BITEX recognized the potential and mission of Casio calculators in helping students learn mathematics effectively, embrace logical thinking, and develop problem-solving skills.
In 1993, BITEX officially became the exclusive distributor of Casio calculators in Vietnam, marking the beginning of a resilient journey.
BITEX – Casio: Pioneering Innovation, Reliable Partner
Throughout Casio’s 60-year journey, the calculator has been more than just a computing tool. For millions of users, it has been a trusted companion, present in their daily lives and even sparking career dreams.
Casio has become a part of the memories of countless students – those who struggled with equations, anxiously pressed keys during exams, and smiled upon finding the correct answer. In each of these moments, Casio calculators were there, quietly and steadfastly building value for the community through a belief in education.
The 60th anniversary of the first Casio calculator (1965 – 2025) also offers an opportunity to reflect on the impressive journey of BITEX and Casio in Vietnam. Today, Casio has become a national brand, closely associated with almost every student, teacher, parent, and working professional.

The colorful calculators feature a youthful and modern style.
BITEX not only contributes to product distribution but also collaborates with Casio to introduce models that cater to the Vietnamese market, including the student-oriented fx-580VN X and fx-880BTG.
In the digital age, the role of handheld calculators remains undiminished. On the contrary, with technological advancements, user-friendly designs, and intelligent features, Casio continues to be an invaluable tool for Vietnamese students and professionals, enhancing their learning and working efficiency and optimizing their computing needs.
32 Years of Accompanying Vietnamese Education
Beyond being a distributor, BITEX assumes the role of a “trendsetter.” With a long-term vision, BITEX not only brings products to the country but also diligently promotes Casio calculators in every region, school, and among students of all levels.
Since 2000, BITEX has collaborated with the Ministry of Education and Training to integrate calculators into teaching and examinations. The annual Casio Math Competitions have become prestigious intellectual playgrounds, fostering a culture of creative learning and technological application in schools.

BITEX coordinates with the Departments of Education and Training to organize annual Casio Math Competitions.
Another significant milestone is the localization of products, enabling Casio to truly “speak Vietnamese” with local students. Models like fx-570VN Plus, fx-580VN X, and the recently launched fx-880BTG are tailored to the local curriculum and integrated with unique features for the domestic market. This is a testament to the close collaboration between BITEX and Casio, reflecting their deep and long-term commitment.
Proud of the Past – Confident in the Future
Thirty-two years is not a short journey. However, for BITEX and Casio, it is just the beginning. Driven by a belief in the power of knowledge and the enduring value of education, these two brands continue their mission into the future.

This journey continues – on desks, in exams, on workstations, in factories, and in the dreams of Vietnam’s youth. Casio is now not just a product but a trusted companion, symbolizing determination, creativity, and hope for a brighter future.
