Why can't Alipay receive the health code of the elderly?

No application. Alipay can't get it because it didn't apply for a health code, so the elderly at home can let their families do it for them without applying. The "health code" is based on real data and can be generated by citizens or people who have returned to work through their own online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city.
