Alf.io-PI GPLv3 GitHub repository RaspberryPI-powered, touchscreen, offline-capable, high throughput check-in station for performing check-in for big events and printing attendees’ badges on-site. Upon first startup, stations form a cluster and download an encrypted list of attendees from the Alf.io instance. Data related to an attendee can be decrypted only upon scanning their ticket.

Thanks to the resilient architecture, stations can operate offline and still guarantee that one ticket cannot be checked in twice on two different stations.
