1, adding non-contact function. The first generation of social security cards was magnetic stripe cards. When using social security card, you need to swipe your card quickly on the card reader. This kind of magnetic stripe card can record information and its confidentiality is not strong, so it is easy to be copied. The second-generation social security card changed the past credit card into a plug-in card, while the second-generation card used an IC chip encryption card, belonging to the bank. The social security card has added the function of payment password. On the basis of the second generation social security card, the third generation social security card adds the function of contactless card reading. We only need to put the social security card near the card reader for a certain distance to get the information.
2. Increase the function of small quick payment, which is mainly used for transportation; It has also increased other government public service applications such as library lending, annual cards for civil servants, credit cards for tourist attractions, and subsidies for benefiting the people and farmers. The third generation social security card can be used as a bus card, and the social security card adds the logo of the Ministry of Transport. Cardholders can use the third-generation social security card to swipe their cards in more than 300 cities across the country and take public transportation, subway and other modes of travel. This function is very useful for the elderly. In most cities, the elderly can take buses for free. In the past, you needed to apply for an elderly bus card to take the bus for free. Now you only need to use a social security card to take the bus.
3. The application technology is more powerful. The third generation social security card adopts domestic encryption technology, such as personal digital certificate function and biometric function, which is more secure. It can be seen that the function of the third-generation social security card is more powerful, and now many cities are carrying out the card replacement work, so I suggest you take the time to replace your social security card with the third-generation social security card.
