Recently, Tencent has partnered with the National Healthcare Security Administration to introduce a 'Scan' feature within WeChat, allowing users to access detailed drug information. By scanning the drug's traceability code, users can retrieve comprehensive details including sales records, indications, usage instructions, and dosage recommendations, thereby ensuring the safety of medications. Currently, this feature encompasses a substantial portion of the drugs listed in the National Healthcare Security Administration's catalog, and with ongoing system enhancements, it aims to achieve full traceability of sales information for every drug.
