How to get bar code in Action Email

Hi, we would like to add a bar code with the student's ID number to an email that is created through Action. That way, the student can show their Qualtrics wellness email and use it to scan in to school. Otherwise, the student has to show their Qualtrics wellness email with their iPad in one hand and scan their student ID with their other hand to scan in to school. If the student is also trying to carry something else, like a band instrument, it can easily slow down the morning process.
Currently, the fonts available in Action do not include a bar code font. But it might be possible to add this since the bar code is after all, just another font (see article at https://www.idautomation.com/barcode-fonts/woff-web-fonts/). Has anyone been able to add some HTML to an Action email to create a bar code on the email?
Thanks,
Van Tang
