What to do if your U-card is frozen

Common reasons for freezes

• Compliance review: large or frequent transactions, a need to explain the source of funds, or KYC details needing an update. KAST officially says large transactions may be flagged for a compliance check.
• Restricted merchants or transaction types: some platforms block specific merchants — KripiCard officially lists Steam, Uber and others.
• High chargeback or refund ratios: KripiCard requires these below 15%.
• Region and access: the issuer detects access from a restricted region; ExCards officially says using VPNs to disguise your country may lead to card closure.
• Platform or issuing-partner changes: an issuing bank changes policy or the service shuts down — DuPay's website already shows a termination notice.

What to do

1. Stop topping up until the issue is resolved.
2. Read official notices: in-app messages and your registered email, to find the reason and the documents requested.
3. Contact support through official channels only: in-app support or the email published on the official website; be wary of "agents" who message you first or ask for an "unfreezing fee".
4. Provide genuine documents: your own ID, source-of-funds explanations or transaction details as requested — never borrowed or altered material.
5. Switch payment methods: move subscriptions and ad accounts on that card to a backup method to avoid repeated failures.
6. Keep records: ticket numbers, emails and screenshots.

Reducing the risk of a freeze

Use the card within the issuer's published policy: only your own genuine documents, no use from restricted regions, no tools to disguise your location, no blocked merchants; top up as needed rather than holding large balances; and keep chargeback and refund ratios low.

Frozen, closed and shut down

A freeze is usually temporary: once the cause is resolved the card is restored and the balance is still in the account. A closure means the card is shut; the balance usually returns to the platform account under its terms, and a replacement may cost a fee. A shutdown means the whole service stops — DuPay's website already shows a termination notice — and whether balances can be recovered depends on the platform's arrangements, which is the riskiest case. Check official notices to see which one applies.

Cards to look at

These three cards' official pages state, respectively, compliance reviews, blocked merchants and chargeback ratios, and a service termination.

KAST: KAST is a Visa card built around spending stablecoins. Generous limits and broad chain support, but confirm spending-side fees in the in-app preview. Accepts business docs. Best for stablecoin holders and small businesses that need high spending capacity; not for users who need frequent large ATM withdrawals. Read the full review

KripiCard: KripiCard is a virtual-only card platform. Publishes the bulk issuing and limits ad teams care about; the price is a 4% + 1 USD top-up fee. Issuance 5 usd; total cost at non-usd merchants 4.6%. Best for ad teams that need many virtual cards to separate accounts; not for small individual users sensitive to top-up cost.

DuPay: DuPay (app name Dupay Pro) was one of the USDT virtual-card products marketed to Chinese-speaking users. The official site announces the service is terminated — do not top up; existing users should contact the official email about balances. Read the status page
