The scan code bar on the hospital image package cannot be faked. When patients register, they will receive information packages issued by medical technicians. After the image examination and results come out, patients can scan the QR code of the report posted on the data package with mobile phone WeChat anytime and anywhere, and click according to the corresponding prompt steps to see the electronic diagnosis report and cloud film. If the QR code is forged, it is illegal. The legal basis is: Article 12 18 of the Civil Code of People's Republic of China (PRC): Patients are harmed in medical activities.
