The credit card of Guiyang Bank can be swiped without setting a transaction password, and the cardholder can choose to set or not set a password. Compared with a credit card without a password, setting a password has the following advantages:

1, it is safer to have a password. Most credit cards support signature+password authentication. Keep the password in mind and you can change it at will. If the bank card with password is forged, the cardholder is not at fault for the disclosure of password, and generally does not bear the responsibility for the loss of funds in the bank card account.

2. When the credit card is lost, password payment brings more security to reduce the risk of funds, while there is more possibility without password. Because in the case of credit card loss, the bank defaults that the card is lost due to the cardholder's fault, so the risk and financial loss are borne by the cardholder.
