There will be no danger. It is normal for others to know the card number of the bank card. For example, if you need someone to remit money to your account, just give him the card number as long as you don't know the password. It is useless for the other party to have a copy of your ID card without the original, because he needs to know the password when he wants to withdraw money from your bank card. Now he needs to withdraw more than 50 thousand money from his account, and he also needs the original ID card (the copy is not accepted) and his signature. Or you are worried that he will open other accounts as your agent, so it will not work without the original. But just in case. It is best not to provide copies of your ID card and bank card to others casually.

1, ID card:

It is a document used to prove the identity of the holder, which is mostly issued to citizens by governments of various countries or regions. It will be used as a tool to prove everyone's unique citizenship. With the emergence of a large number of new technologies, ID cards can contain biometric information, such as photos, facial features, palm features, iris scanning recognition or fingerprint recognition. Other information that usually appears on the ID card (or database) includes: full name, parents' name, address, occupation, nationality (in many countries), blood type and coagulation factor.

The resident ID card of the People's Republic of China is written as "ID card" before 1984. 1On April 6th, 984, the State Council issued the Regulations on the Trial Implementation of Resident Identity Cards of the People's Republic of China, and began to issue the first generation of resident identity cards. 1September 6, 989, the Regulations of the People's Republic of China on Resident Identity Cards was promulgated and implemented. On March 29th, 2004, Chinese mainland officially began to renew the second-generation resident ID card with built-in contactless IC card smart chip. 2065438+In August 2005, the Opinions on Establishing the System of Receiving and Reporting the Loss of Resident Identity Cards in Different Places was reviewed and adopted, aiming at facilitating people to renew and reissue their resident identity cards in different places and handle the reporting of the loss of resident identity cards.

According to the current practice, after losing your ID card, you need to report the loss to the police station where your household registration is located. It seems to have gone through the procedure of reporting the loss, but this procedure is meaningful only if it reissues the identity card and the public security organ keeps the file for future reference.

From July 1 2007, the "three systems" for accepting, reporting and claiming lost resident identity cards in different places were fully implemented throughout the country, and the policy of difficulty in settling down was refined, so as to basically solve the problem of people without household registration before the end of the year.

2. Bank card:

It is a credit payment tool issued by commercial banks and other financial institutions and postal savings and remittance institutions to the society with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal, etc. Bank cards include credit cards and debit cards. Because all kinds of bank cards are made of plastic, they are also used for deposit and withdrawal and transfer payment, so they are also called "plastic money".

The size of bank cards is generally 85.60× 53.98 mm (3.370× 2.125 inch), and there are also mini cards and irregular cards that are 43% smaller than ordinary cards.

By the end of 20 16, China had issued a total of 6.37 billion bank cards, and the national population was close to1400 million. On average, each person holds nearly five bank cards, but the cumulative number of live cards is only 41800,000, and the number of "sleeping cards" is 21900,000, accounting for 1/3. In other words, everyone holds nearly two "sleep card" on average. Starting from 20 17, the bank's management of sleep card has been continuously strengthened, and some "double zero cards" will be frozen from 1 1.
