The Visa O2 card offers more than just cutting-edge technology; it comes with a host of attractive promotions, market-leading interest rates, and green consumption encouragement programs, helping customers control their finances while contributing to environmental protection.
Technology that enables the Visa O2 credit card to measure CO2 emissions
You may not be aware, but every item you purchase, from food to household goods, fashion, and technology, generates a certain amount of CO2 – a factor that impacts the environment and climate change. More and more Vietnamese people are concerned about this issue and want to adapt to green and sustainable consumption trends, aiming to reduce their CO2 footprint in their daily lives.
In this context, the Visa O2 card helps cardholders measure greenhouse gas emissions (CO2) for each item they purchase, becoming a pioneering tool to help customers build a green and sustainable lifestyle.
The amount of CO2 emitted will be provided by Sacombank to customers in regular transaction notifications. These data not only help customers understand their carbon footprint but also serve as a basis for cardholders to easily adjust their shopping habits, choose more environmentally friendly products, prioritize green consumption, and reduce CO2 emissions, thus contributing to ecological preservation.
“With the Visa O2 credit card, we aim to provide not just a superior financial solution but also accompany our customers on their journey towards a sustainable future,” said a Sacombank representative. “By quantifying the CO₂ generated from everyday purchases, customers can proactively change their consumption behavior, join hands to reduce environmental impact, and contribute to a greener tomorrow. This is part of Sacombank’s commitment to promoting green finance and sustainable development in Vietnam.”
Embark on a Green Journey with the Visa O2 Credit Card
With the Visa O2 credit card, customers can choose a physical card made from recycled plastic collected from ocean waste or a virtual card to reduce plastic use.
When using the virtual card, customers enjoy a lifetime waiver of annual fees and can start spending immediately after registration. Specifically, customers only need to activate the card on the Sacombank Pay application, add it to Apple Pay/Google Pay/Samsung Pay/Garmin Pay, and enjoy seamless and secure in-store payments.

Additionally, for each new Visa O2 card issued, Sacombank will contribute VND 50,000 to the “Sống Khoẻ” Fund, an initiative by Sacombank in collaboration with the Vietnam Youth Union and the Vietnam Student Union to promote community activities and encourage green and sustainable living, especially among young people.
A Green Card with 5x Benefits for Modern Consumers
The Visa O2 credit card is more than just a convenient payment method with state-of-the-art carbon measurement technology; it elevates the green lifestyle of its users through a range of special benefits. Customers who open a Visa O2 card and accumulate a spending of VND 2 million or more within the first 30 days of activation will receive a cashback of up to VND 600,000.
Moreover, for green purchases at Xanh SM – an all-electric mobility service, Vinamilk – Vietnam’s leading dairy brand, or Decathlon – a sustainable sports fashion brand, Visa O2 cardholders will enjoy a 10% cashback, up to VND 300,000 per transaction.
One of the most notable features of the Visa O₂ is its market-leading interest rate of only 0.8%/month, specifically offered to student cardholders. This gives customers peace of mind when using the card, especially in situations where they need immediate financial support, allowing them to maintain their financial flow for more important goals.
Cardholders can also proactively convert their purchases into 0% interest installments directly on the Sacombank Pay app. For transactions over VND 5 million, cardholders can opt for 3 or 6-month installments and enjoy a conversion fee waiver of up to VND 1 million. Whether it’s a vacation, a skill-enhancing course, or a new tech gadget, the Visa O2 card lets you enjoy life’s experiences without financial stress.

Additionally, cardholders can apply for a consumer loan online 24/7 on the Sacombank Pay app, with interest rates as low as 12%/year and flexible tenors ranging from 2 to 60 months, providing them with financial flexibility.
