Explanation and Preventive Measures Regarding Frozen Bank Cards

I. What is a Frozen Card?

A frozen card refers to a bank card being frozen due to abnormal transactions or risk control measures implemented by banks or judicial authorities, resulting in the inability to receive payments, transfer funds, or withdraw cash normally. There are two main types of freezes:

1. Bank Risk Control Freeze

• Banks may freeze accounts based on anti-money laundering (AML) and risk control strategies when they detect high-frequency transactions, abnormal fund transfers, or large abnormal fund flows.

• Typical situations include:

• Frequent payments and receipts with a large number of transaction partners;

• Excessively frequent large transactions within a short period;

• A long-term extremely low account balance followed by a sudden large transfer;

• Transaction notes containing sensitive words such as "USDT," "BTC," or "ETH."

2. Judicial Freeze

• Judicial authorities may freeze bank cards temporarily or permanently due to investigations.

• Typical situations include:

• The account's funds have been linked to financial chains in cases of fraud, money laundering, or illegal fundraising;

• The counterparty in a transaction is involved in a criminal case, and the police are tracing the financial chain, leading to the freezing of related bank cards.

• Types of Judicial Freezes

• Temporary Freeze (36-72 hours): If the bank card did not directly receive illegal funds, it will be automatically unfrozen after the freeze expires.

• Long-Term Freeze (six months to one year, or even longer): The police or court request a freeze, which usually requires the case to be closed or withdrawn before it can be unfrozen.

II. How to Prevent Bank Cards from Being Frozen?

To avoid bank card freezes, users are advised to strictly adhere to the following fund management rules:

1. Fund Management and Transaction Habits

✅ Separate Receiving and Payment Cards: Use the receiving card specifically for receiving payments and the payment card specifically for making payments to reduce transaction frequency and abnormal fluctuations in amounts.

✅ Avoid Frequent Transactions with a Single Bank Card: It is recommended to regularly change the receiving card and promptly transfer funds to a secure account after each transaction.

✅ Schedule your transactions reasonably: Avoid late nights and frequent large transactions to reduce the probability of triggering risk control measures.

✅ Use real-name bank cards for transactions whenever possible: Require the counterparty to use a bank card matching their identity information for payment to avoid receiving transfers from unregistered individuals.

✅ Avoid sensitive transaction notes: Do not include sensitive terms such as "USDT," "BTC," or "ETH" in the transfer notes to avoid being detected by the bank's risk control system.

2. Fund Filtering (Applicable to high-frequency trading users)

✅ Alipay Fund Filtering:

• Step 1: After receiving funds on the receiving card, top up the Alipay balance or Yu'e Bao (a merchant code can be applied for for top-up);

• Step 2: Then transfer funds from Yu'e Bao to the paying card to complete the fund filtering. (Applicable to funds up to 1.15 million)

✅ Investment Platform Filtering (Applicable to users with large transactions)

• Step 1: After receiving funds in the receiving card, transfer them to Lufax or other investment platforms;

• Step 2: Purchase short-term investment products, and withdraw the funds to a new bank card upon maturity.

• Note: This method involves delays in fund arrival and platform risks. Choose reputable investment institutions carefully.

✅ Cash Deposit and Withdrawal Filtering (Applicable to users with small transactions)

• Step 1: After receiving funds in the receiving card, withdraw the cash;

• Step 2: Deposit the funds into another secure bank card to complete the fund filtering.

3. Account Management Measures

✅ Avoid excessively high balances on single bank cards: Regularly clear account funds and avoid storing large sums of money for extended periods.

✅ Avoid sudden large transactions on bank cards that have not been used for a long time: Banks may consider such transactions abnormal and trigger their risk control systems.

✅ Transfer funds promptly after receiving payment: After receiving funds, it is recommended to transfer them to a secure account or withdraw them as soon as possible to reduce the risk of being frozen.

✅ Maintain a good bank credit record: Avoid involvement in gray market activities or high-risk transactions to prevent accidental freezing due to account association.

III. What to do if your bank card is frozen?

1. Bank risk control freezing handling methods

• Step 1: Contact the bank where you opened the account

• Inquire about the reason for the freeze, the type of freeze (temporary/long-term), and the unfreezing method.

• Step 2: Submit relevant supporting documents

• If frozen due to abnormal transactions, users can provide the bank with proof of identity, proof of the source of funds, transaction records, and other materials to apply for unfreezing.

2. Judicial freezing handling methods

• Step 1: Contact the investigating authority

• Understand the reason for the freeze, the freeze period, and case details.

• Step Two: Prepare Unfreezing Documents

• Identification (ID card, passport, etc.)

• Transaction records (stamped by the bank)

• Proof of income (e.g., payslips, contracts; avoid using "cryptocurrency trading" as a reason)

• Proof of employment (proving the user's normal economic activities)

• Step Three: Cooperate with Judicial Authorities

• Provide relevant materials as required and cooperate with the investigation. In some cases, the freeze will be automatically lifted upon expiration; in others, it may require the case to be closed before an unfreezing application can be made.

• Special Note: After the bank card is unfrozen, please transfer the funds out as soon as possible to avoid a second freeze due to the case.

IV. Summary

A frozen bank card may affect your cash flow; therefore, users are advised to take precautions against risks in advance and strictly abide by the platform and bank's transaction rules.

🔹 Avoid high-frequency, large-amount transactions; diversify your fund management.

🔹 Do not accept payments from unregistered individuals; use separate cards for receiving and making payments.

🔹 Filter funds to reduce the probability of triggering bank risk control measures.

🔹 After funds are frozen, contact the bank or judicial authorities immediately and submit the required documents.
