Chip credit card, also known as chip credit card, is the most advanced credit card in the world. Its characteristic is that in addition to the traditional magnetic stripe identification system, a highly integrated chip is used as the information carrier, which lays a solid foundation for the security and function expansion of credit cards. At present, major card issuers in Hong Kong and Taiwan are gradually upgrading from traditional credit cards to chip credit cards, and domestic ICBC has also taken the lead in launching chip credit cards.
