It may be that the previous card is bound to other main cards, so it is impossible to add new membership information. You can log in to Alipay, find the Su Kang code, and delete the previously bound information. Of course, if you can't do the above operation, it may be a network problem. Please check whether the network settings are normal. It is also possible that there are too many family members bound, and only five can be bound at most.
Sukang Code was implemented in Jiangsu Province during the epidemic prevention and control in COVID-19. People who have entered and returned to the Soviet Union and those who work, study, live, travel or stay temporarily in the Soviet Union need to apply and use it. Su Kang code classifies people according to different risk levels of red, yellow and green (corresponding to high, medium and low respectively), and recognizes each other in the whole province and the three provinces and one city in the Yangtze River Delta.
