I developeed this application for iOS and Windows several years ago for scanning tickets at Interactive Ticketing events.
It has been used by thousands of consumer shows and fairs that receive high traffic of new visitors. It must perform well in conditions where access to internet or wired electrical outlets are difficult.
v6.1.12
and follows alpha, beta, and stable cycles with multiple versions in the field at a time.It is currently on its 6th major version, I'm considering a version 7 with Electron and/or React Native.
The iOS version is primarily for iPods that are inserted into a barcode scanner accessory that encases the iPod, but some smaller events may use iPhones with the camera to scan tickets.
Users typically plug one or more wired USB barcode readers into a netbook running this software.
