Tools will be run once a year to share the Drachenfest Tickets I buy in bulk (cheapest early bird price) with my friends. (bulk size ~20 tickets) human readable code is needed for registration, qr code is required to get access at eventlocation. (qr on smartphone is tested and DF approved!)
A simple CSV where the first column has the names and the 2nd colum the code. Name it 'data.csv' The images will be saved in the execution path.
