How can the elderly without smart phones check the results of nucleic acid testing?

"Beijing Health Bao" has the function of inquiring health codes and nucleic acid test results on behalf of others. The smart phone can be used by others to query the test results through two paths, namely, "health code query for young and old Xian Yi (suitable for people under 16 and over 60 years old)" and "check the nucleic acid test results on behalf of others (regardless of age)", and input information such as name and ID number as required to query other people's nucleic acid test results. If the elderly need to enter public places, they can ask the staff of the places to help them check.
