The product takes the form of an epoxy resin keychain tag. The front features a creative design with auspicious meaning, while the back is printed with a QR code. First-time use requires inputting emergency contact information and medical emergency details (such as medical history, drug contraindications, and emergency medications). Attach the product to personal items or wear it on your person. If an item is lost or a person goes missing, a kind-hearted individual can scan the code and authorize their phone number. The emergency contact will then receive a phone call and WeChat message (including location information), notifying them to contact the finder. Scanning the code also allows access to medical information, providing crucial details for treatment. This product protects user privacy while enabling assistance when needed.
