In order to protect the security of credit cards, many banks have launched credit card "lock" services, and some bank apps can even verify the authenticity of short messages.

Incidents of credit card theft have occurred from time to time. On August 15, the reporter learned from Shencheng Bank that a number of banks launched free services such as "locking" credit cards and identifying the authenticity of bank short messages online to improve the security of credit cards and ensure the safety of citizens.

It is understood that at present, most banks such as ICBC, CCB, Xingye, Minsheng, China Merchants Bank and CITIC have launched credit card "security locks", and different banks have different "security locks" functions. For example, some bank credit card "security locks" are subdivided into "overseas locks", "regional locks", "night locks", "overseas payment locks without cards" and "limit locks", while other bank credit card "security locks" can be opened and closed with one key, without security verification such as password inquiry, transaction password and SMS password. According to the staff of the bank, citizens log in to the bank's mobile banking and online banking, enter the credit card "security settings" page, and turn on the "security lock" function. The system will automatically control the selected credit card to prevent risks such as being stolen. For example, cardholders can choose to lock their credit cards from 24: 00 to 7: 30 the next day, and do not use credit cards during this period.

At the same time, in order to prevent citizens from receiving fraudulent short messages sent by fake bank customer service, some banks have also launched online short message authentication services. A bank credit card APP has an "online verification" option. Users click "Simple Check" and "Distinguish Authenticity", paste the content of the short message to be verified in the text box and submit it, and then they can know whether the short message is sent by the bank.

After encountering uncertain short messages, I finally have a verification channel. I believe this is a great good news for the majority of card friends.
