UnionPay

UnionPay is China's card network and the largest in the world by cards issued, with acceptance extending across Asia and into most international markets. Brokers with Asian client bases commonly support it, either as a card payment or through a UnionPay online banking flow.

How it behaves at a broker

Mechanically it works like any other card deposit: instant, with confirmation by SMS code or the bank's app. Withdrawals follow the refund rule that all card networks impose — funds return to the card that funded the account, up to the amount deposited, and anything above that leaves by bank transfer.

The constraint that matters

For cards issued in mainland China, the limit is not the broker's. Chinese residents are subject to an annual quota on converting renminbi into foreign currency, administered through the banks, and cross-border card transactions are reported against it. Issuers additionally decline categories of foreign merchant, and payments to financial and trading merchants are among the ones most often blocked. A deposit can therefore fail at the issuer with no explanation reaching either you or the broker. Cards issued outside mainland China — in Hong Kong, Singapore or elsewhere — do not carry the quota and behave like ordinary international cards.

Practical notes

• A declined UnionPay deposit is usually an issuer decision, not a broker one; the broker's support cannot override it.
• Currency conversion is done by the issuer at its rate, plus any cross-border fee. Funding a USD account from a CNY card carries that cost each time.
• The card must be in the account holder's name — enforced strictly here, since third-party card use is a recurring compliance problem in the region.
• Some brokers route UnionPay through a local payment partner rather than the card rails, which changes the limits and the withdrawal path. Check what the cashier actually says.

Regulatory context

Margin foreign-exchange trading with offshore brokers occupies an unsettled position in mainland Chinese law. That is a question about the activity, not the payment method, and it is worth understanding before choosing a broker on the strength of its cashier.
