The third generation ID card is an upgraded version, which will contain a variety of information, such as medical cards, bank cards, shopping cards and so on. One of the reasons for taking blood is to check your blood type and include your DNA for easy retrieval. Once a crime is committed, it will help the police catch the suspect in time.
Second, many twins used to look alike, so they often used the same ID card. Blood collection is now required to better distinguish the identity information of such people.
Third, suppose that a major accident happened unfortunately, which made it unrecognizable. According to the blood information on the ID card, you can confirm your identity in time and inform your family to come and claim it.
In addition, collecting blood and backing up everyone's blood type records can build a huge blood database, which is of great help to medical assistance in China.
Of course, there is also a social reason, that is, many people choose micro-circles for beauty. If the ID card is issued before the micro-circle, it will be embarrassing, and it is very likely that they will not recognize it by means of transportation. Such incidents often happen in reality, so this time, everyone need not worry. After all, blood cannot be changed.
