How to generate PDF417 barcode for US IDs?

Hi everyone,

I’ve been working on a small tool related to PDF417 barcode generation (commonly used in US/Canada formats).

I wanted to ask:
- What features do you usually need in a barcode generator?
- Any common problems you face?

Would love to get some feedback from the community.

Thanks!
