1 Most cards in China are magnetic stripe cards. IC refers to a chip card without a magnetic stripe. Integrated circuits are divided into contact type and non-contact type. A magnetic stripe is an ordinary magnetic stripe card; Magnetic stripe +IC means that the card not only has a magnetic stripe, but also a chip; Magnetic stripe +IC+ contactless means that the card has a magnetic stripe and a contactless chip. The second-generation ID card is a non-contact IC chip card, which has anti-counterfeiting technologies such as directional photochromic "Great Wall" pattern, anti-counterfeiting film, optically variable storage "China China", miniature character string "JMSFZ" (Chinese pinyin: JuMinShenFenZheng, resident ID card), and ultraviolet fluorescent printing "Great Wall" pattern.

3. According to the requirements of the international card organization, banks in China will gradually change the existing magnetic stripe cards into ic chip cards, and magnetic stripe+chip is only a transitional product.

Because IC chip card adopts smart card encryption technology, the security of the card is greatly improved, which fundamentally eliminates the possibility of copying cards (fake cards) and provides a safe environment for the use of credit cards. At present, the upgrading of domestic pos machines has been basically completed. Banks such as ICBC, CCB and BOC have started to issue chip cards in batches. ICBC issued the largest number. It has only been launched in Europe for nearly five years, and it has not been fully promoted.
