Whether we add scannable barcodes to the OPAC via a JS library (as suggested in Bug 26777) or via an API (Bug 26692), it would be good to provide the library with a way to define the format for the barcode output. This could also be used as the default in the patron card creator.
Seems like a reasonable idea to me.
