Is it safe to send health code photos when staying in a hotel?

The health code will not reveal personal privacy. The health code is generated by a special information system, with strict coding rules and privacy protection, and people who use WeChat or Alipay cannot identify it. Health code is a personal two-dimensional code based on actual real data, which is declared by citizens or people who have returned to work, and then audited by the background. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.
