Effortless Notification Sign-off with a Single QR Code
Original: https://cli.im/article/detail/1851
As a kindergarten teacher, I find parent groups essential for communication in every class, especially during the kindergarten years—a stage that makes parents particularly anxious, leading to highly active group chats. For daily minor announcements, the group announcement feature works well and facilitates easy tracking. However, it falls short for important documents that require careful parental review and signatures. Additionally, when parents need to upload photos or videos, the group chat can quickly become cluttered, making organization and statistics cumbersome.
To address this, I now use QR codes to distribute crucial notifications. These codes allow parents to sign directly, eliminating the need to print notices and send them home with the children.
Implementation Process
- Create a notification QR code containing the notice document and fields for parents to fill in.
- Post the notice and QR code in the group chat, instructing parents to review and sign upon receipt.
- Track the number of parents who have signed and responded, identifying those who haven’t.
- Follow up individually with non-responding parents to remind and urge them to complete the process.



Benefits of Using QR Codes
For more critical notifications, QR codes can embed the notice file, requiring parents to read it before signing. The signed information can be directly exported from the backend and printed for submission, preventing issues like students losing the notice. QR codes also facilitate the collection of photos and videos, ideal for gathering activity videos or daily homework photos. They allow batch exports from the backend, eliminating the need for parents to email attachments and for teachers to download them one by one.
Limitations
Currently, there's no feature to preload a list of individuals, requiring manual tracking of non-responding parents. My workaround involves exporting the submitted data and using Excel's VLOOKUP function to quickly match and identify which students' parents haven’t responded. It would be beneficial if CaoLiao could enhance this feature to automatically track non-respondents. For everyday minor notices, group announcements remain the better option.
Beyond notifications, QR codes have versatile applications, such as visitor registration at security posts,实名认证 screenshot submissions for the "National Anti-Fraud App," or small event sign-ups. Although CaoLiao offers a paid version, the free version suffices for my needs, proving incredibly practical for budget-conscious institutions like schools.

Lately, I've been experimenting with creating a unique QR code for each child as a growth log. Our kindergarten requires daily reports to parents on their child’s activities, including drinking water, using the toilet, dressing, eating, and emotional state.
By assigning each child a QR code shared with their parents, I can simply upload daily photos and videos. Parents scan the code to view updates on their child. I can also add private evaluations for each child. If anyone has better methods, I’d appreciate your suggestions in the comments.
