What does it mean that the postal savings bank card is restricted from trading?

The reasons for the restriction of postal savings bank cards are as follows:

1, incomplete information. If the cardholder's ID card is expired and not updated, and the mobile phone number is invalid, the bank card will be restricted to some channels.

2. The account is risky. For example, if the account involves the risk of gambling fraud, let the bank stop trading.

3. Enter the wrong password several times in a row. If the cardholder enters the wrong password many times during the use of the bank card, which exceeds the bank's limit, it is easy to be restricted from trading.

4. It's been useless for a long time. If the user's bank card is not used for a long time, it will be classified as a sleeper and will also be restricted from trading.

When the cardholder uses the postal savings bank card, the system prompts that the transaction is limited, which means that the bank card cannot be used normally and needs to be handled at the bank.
