I am developing a web application that interacts with an Omnikey 5422 NFC reader. I need help with writing data to an NFC card using JavaScript. I understand that the Omnikey 5422 supports communication with web applications, but I am struggling to find the correct approach to write data to the card through JavaScript.

I initially tried using Python Django with the Psycard library to interface with the Omnikey 5422 NFC reader, and it worked fine on my local server (localhost). However, when I tried deploying it to the production server, it didn't work as expected. I realized that for client-side support, I need to use JavaScript.

I expected to find a JavaScript solution or library that would allow me to communicate with the Omnikey 5422 and write data (such as URLs or text) to NFC cards directly from my web application running on the production server.

However, I am unsure of how to interface with the Omnikey 5422 from the client side using JavaScript and write data to the NFC cards in a production environment.
