Practical guide
When running Facebook or TikTok ads, many people use their salary card as the main payment source. It is convenient but easily mixes personal spending with the ads budget, and if the card has problems it affects daily life. This article explains how to set up a separate virtual card to pay for ads, based on common payment options in Vietnam.
A salary card is usually linked to your main bank account and used for daily expenses. When you use this card to pay for Facebook Ads or TikTok Ads, you may run into these problems:
Using a separate virtual card for ads lets you set a clear spending limit and easily stop or replace it when needed without affecting your main card. This is the approach many small advertisers in Vietnam are using.
The table below summarizes the pros and cons of common methods for paying for ads or international services. Note: no method guarantees 100% approval.
| Method | Best for | Limitations |
|---|---|---|
| Domestic Napas card | Good for Vietnamese websites. | International gateways often do not accept domestic BINs. |
| MoMo / ZaloPay | ChatGPT.com already supports MoMo for Go/Plus/Pro plans in Vietnam. | MoMo/ZaloPay still cannot fill in the card form for Claude, ads, or a US Apple ID. |
| Vietnamese Visa/Mastercard | Domestic payments and some international services. | May be blocked by BIN, lack 3DS, or not match the payment country. |
| Virtual card (used in the App) | Flexible for ads and digital services; separate from your salary card. | Requires topping up USDC/USDT in the App before use; does not guarantee approval for every merchant. |
Which method to choose depends on your needs and how much control you want. For Facebook/TikTok ads, virtual cards are often preferred because you can create a dedicated one and track changes.
Reference process (details and specific conditions are shown in the App):
Note: There is no guarantee the card will be accepted for every ad account. Facebook/TikTok may require verification or decline the card depending on their policies. Check carefully before running large campaigns.

Beyond ads, virtual cards are also useful for digital services that require an international card:
