[Koha-devel] Patron cards

Hi, we are working with patron cards and we need new features. Our idea is add a possibility for to have a card similar to: http://www.indiamart.com/creationtechnics/pcat-gifs/products-small/barcode-c... https://www.gprc.ab.ca/departments/library/images/screen%20captures/student_... Are there more information and documentation about this? Thanks
