Credit cards without chips are magnetic stripe cards. Unlike chip cards, magnetic stripe cards can be used by brushing magnetic stripes on POS machines. However, the magnetic stripe card has few functions, high degaussing risk and poor security, and it is easy for others to steal personal information, which in turn leads to the theft of credit cards. It is suggested that the cardholder go to the business hall of Shanghai Pudong Development Bank in time and ask the staff to replace the new chip card.
