Credit cards can be swiped without a password, because businesses that can make non-magnetic and non-secret payments have signed such cooperation agreements with banks and obtained authorization from banks. Customers only need to provide card number, expiration date, verification code, cardholder's name and ID number, and can make overdraft consumption without providing password. If the transaction is cancelled, the money will be automatically returned to the credit card by the merchant without cash or other transfer payment.
If you want to swipe your card without a password, you can go to the bank counter or online banking to set up a credit card exemption or a credit card quota exemption. It is suggested to set the credit card limit interest-free. For example, credit cards below 500 yuan are confidential. This is safer and can prevent brush theft.
