Yes, it's safe. Because Guangfa Credit Card displays the error code 0 1, this is a common phenomenon on the pos machine of Guangfa Credit Card, and it is caused by the card reading error of the pos machine. In the end, there will be a prompt of transaction failure, and personal information will not be revealed, which is very safe. After the next day, as long as the pos machine runs normally, it can continue to be used, so it is ok and safe to use the error code 0 1 of Guangfa Credit Card the next day.
