5kmrun barcode in iOS wallet

[etabakov]

There is a screen in the app that displays a barcode which runners use to checkin after completing a run. It would be very convenient if runners can add this barcode to their apple wallet and not have to open the app.

Important: Currently, we are using code39 barcodes. Need to double check if this is supported by apple wallet and if not what other barcodes are supported by the barcode readers.
