Background and Function
Before the recent Shanxi C-class exam, I had an idea to design a QSL card with an NFC tag. Previously, I had seen some enthusiasts putting an NFC tag or QR code on their cards so that when the recipient received the card, they would have to tap it or scan the QR code and fill out a form. However, I thought it was a bit impolite to ask them to fill out a form, so I came up with the idea of directly writing specific URLs into different NFC tags, which would then automatically redirect to the page associated with the recipient's callsign after being tapped.
To address the different types – "qso", "eyeball", "swl", and "eyeball-sxc" – I created a simple display page using AI assistance. This page displays different content based on the URL parameters passed to it. Additionally, to address the issue of manually creating NFC tags for the "eyeball" event when there was no physical presence, I designed a system where the user would be asked to enter their call sign and associated parameters, which are then stored in cookies and on the server. This allows users to fill out the information once and have it permanently saved. Furthermore, when a new page is opened, the system first checks the local cookie and server records to avoid repeated input.
Problem
Currently, we still rely on servers to permanently store the corresponding data. In the future, we plan to use CF (Cloud Functions) for serverless rendering.
