Visa has introduced its Flex Credential feature in Vietnam, allowing cardholders to choose between debit, credit, and other payment options using a single card.
Asia Commercial Joint Stock Bank (ACB) is the first in Vietnam and Southeast Asia to roll out the solution, with VIB set to follow soon through its MyVIB app.
Available via the ACB One app, the feature enables users to switch between payment types depending on their needs.
Beyond debit and credit, Flex Credential can also support loyalty point redemption and, in some markets, access to multiple currency accounts through a single card.
Visa said more banks will adopt the technology by the end of 2025.
The solution incorporates advanced security protocols and provides a unified payment experience, allowing users to manage transactions seamlessly through a single platform.
Visa Flex Credential was first introduced in Japan two years ago in partnership with Sumitomo Mitsui Banking Corporation and Sumitomo Mitsui Card Company.
Known as Olive in Japan, the card has gained over five million account holders and has recorded transaction volumes averaging 40% higher than the national average.
The feature was later expanded to support small businesses, allowing users to toggle between personal and business accounts on the same card.
Visa is also partnering with ACB to support Cashless Day 2025, a local initiative to encourage the adoption of digital financial services.

Dung Dang, Visa Country Manager for Vietnam & Laos, said,
“Flex Credential is Visa’s breakthrough solution that enables the integration of multiple funding sources through a single card credential, providing cardholders with maximum flexibility to efficiently manage and utilise their payment forms.
In specific markets such as the U.S. and UAE, Visa Flex Credential allows cardholders to choose to pay now or pay over time directly from the app, as well as access multiple currency accounts through a single credential – making cross-border payments simple and seamless.”
