Regular mail does not have publicly available tracking information, making it impossible to confirm delivery. Registered mail, while having tracking information, significantly increases the cost of sending, making it much less economical than using postcards.
Therefore, confirming whether a mailed letter has been received is a problem. The current methods of inquiry are not very intelligent and can be quite cumbersome. While scanning and filling out forms is convenient, is there a better solution?
Approach
The method of one-click confirmation based on QR codes is clearly simpler. It involves generating unique QR codes in bulk, and the recipient can scan and click to confirm receipt after receiving the email, without having to fill out a form, thus eliminating unnecessary steps.

Back-end demo
You can clearly see the delivery status, and because each letter has a unique QR code generated, it avoids the problem of only being able to collect delivery information from users who have received the letter, making it difficult to easily view unreceived letters in the future (reviewing past deliveries is very cumbersome).
How can I use it in the same way you do?
Don't worry if you find it difficult; I'm a very lazy person, so it's easy to use.
Get a template
First, register for a "Pasture" QR code account, then click the link to import my template.
Account registration:https://user.cli.im/join
Import template:https://cli.im/share/CCNI8py
Generate QR code
Navigate to the backend and find "Bulk Monotype Templates". Locate your template and click "Generate Bulk Plates", then click on the online form to generate bulk plates.
On the left-hand side, enter the recipient's call sign in the corresponding column, then click "Generate QR Code" in the upper right.
It is recommended to use different folders to implement batch queries.
- Print QR code
Click to go to the QR code download page, where you can print multiple copies on A4 paper and then manually cut them out. Alternatively, you can download the PDF and import it into a label printer.
If you are not satisfied with the page template and QR code style, you can modify them yourself on the template page. I will not elaborate further here.
Also, you don't need to worry about the platform going offline. The "Cǎoliào" QR code has been in operation for over 10 years and was even adopted by government departments during the pandemic. I encourage everyone who uses ham to adopt the solutions I share. (P.S.: This article is not an advertisement.)
The above is my personal method, and I hope it will inspire others to improve upon it. I welcome any suggestions for improvement!
