To sign in via NFC/RFID/ProxCard readers for Liszt attendance credit, you will need to present your card to the card reader. Cards that are read between 30 minutes prior to the event start time and five minutes after the event start time will count towards the event (unless your school has decided to use alternate timings.)
The card reader will beep, flash, or change color if your card was read. If your card was not read, re-present your card.
Your school may require single-swipes or double-swipes per card reader. If you are signing in to a single-swipe reader, you should present your card before the event. If you are signing in to a double-swipe reader, you should present your card before AND after the event for the Algorithm to properly process your swipes.
