I have reviewed some designs circulating online and used the open-source typesetting system Typst. The entire card surface is described by less than 200 lines of clear, readable code, making it easy for other stations to modify according to their preferences. Additionally, you can write a few batch scripts to directly generate engineering files with pre-existing communication information in bulk.
