Dear Colleagues, I need help figuring out what barcode encoding to use with Koha when ordering library cards. Barcode encodings which are available include Code 39 & Codabar. Is there a specific encoding which Koha requires or likes. Also, the library card vendor wants to know if a check digit is required; the check digit signals the barcode reader where the beginning and end of the content is, correct?
