To ensure the long-term stability and usability of your card, please read these guidelines carefully before proceeding. Good card usage habits effectively prevent payment failures, high declined transaction fees, and unexpected card cancellations.
Balance Management & Daily Spending
Whether for daily payments or recurring subscriptions, maintaining a sufficient balance is essential for successful transactions.
Adequate Buffer: Ensure your card balance exceeds the expected transaction amount by 3%–5% to account for exchange rate fluctuations.
⚠️ Safety Reserve: We recommend keeping at least 2–5 USD on your card after spending. Avoid draining your balance to zero to prevent transaction failures caused by insufficient funds for processing or cross-border fees.
⚠️ Note on "0% Fee" Perks: If you enjoy a 0% fee perk, the banking system will still temporarily deduct the fee before issuing an immediate rebate. Please ensure your initial balance is sufficient to cover the full amount upfront.
Nature of Charges: Deductions are initiated directly by merchants. In addition to bank processing fees, you may incur merchant-side taxes, service fees, and other surcharges. If you have questions about specific charges, contact the merchant's customer support directly.
Subscription Services
Subscriptions operate on long-term automated billing cycles. For overseas subscriptions such as ChatGPT, Netflix, and Midjourney, please observe the following:
7-Day Advance Rule: Subscriptions are typically billed automatically. Always verify that your balance is sufficient well before the billing date (preferably 7 days in advance).
⚠️ Set Calendar Reminders: Get into the habit of setting reminders on your mobile calendar for subscription renewals or cancellations.
Strictly Avoid "One Card, Multiple Accounts": Binding the same card to multiple accounts with the same merchant frequently triggers fraud-prevention controls, leading to account bans or the inability to cancel subscriptions.
⚠️ Cancel Unwanted Services Promptly: A subscription is a direct agreement between you and the merchant; the bank cannot cancel it on your behalf. If you do not plan to renew, make sure to cancel directly through the merchant's platform. Otherwise, repeated deduction attempts will incur multiple, costly declined transaction fees.
⚠️ Free Trial Risks: Free trials automatically convert to paid plans upon expiration. Cancel promptly if you do not wish to continue. Failing to do so can result in payment declines, penalty fees, merchant account bans, and even card termination by the bank.
⚠️ Special Notice: Emptying your card balance, toggling the card to inactive in the app, or deleting the card does NOT terminate your subscription agreement with the merchant.
How to Effectively Prevent Declines
⚠️ What is a Decline? A transaction decline occurs when a payment fails due to cardholder-related reasons, such as insufficient balance, a frozen, deactivated, or canceled card, or incorrect card details.
Declined Transaction Fee: The bank processing fee incurred whenever a decline occurs.
An excessively high decline rate will trigger risk controls and may lead to permanent card termination.
⚠️ Do Not Empty Balances to Cancel: Always cancel subscriptions via the merchant platform. Forcing a cancellation by draining your card balance is strictly prohibited.
⚠️ Check Card Status: Before making a purchase, ensure your card is not deactivated, frozen, or canceled.
Verify Top-Up Crediting: Top-ups typically take 1–5 minutes to synchronize. Wait until the updated balance is reflected before initiating a transaction.
Double-Check Card Details: Carefully verify your CVV and expiration date during checkout. Multiple consecutive incorrect entries will cause the bank to lock your card.
Avoid High-Risk Websites: Do not transact on untrusted or disreputable sites to prevent automated blocks by the bank's risk-control systems.
How to Avoid Card Termination
Banks monitor card usage quality in real time. The following behaviors will trigger irreversible card cancellation:
Abnormally High Decline Rate: Frequent, repetitive payment failures on the card.
⚠️ Prolonged Inactivity: Zero balance with no transaction activity over an extended period (dormant card cleanup).
Free Trial Abuse: Repeatedly creating cards to exploit free trials. Merchant complaints will result in all associated cards being blacklisted.
⚠️ Negative Balance Handling: If your balance is insufficient to cover transactions or fees resulting in a negative balance, the system will automatically deduct funds from your asset account, earn account, or other balances. If the deficit cannot be covered, risk controls will trigger permanent card termination.
