Hi All, Many of our card swipe readers in ARMS are malfunctioning currently. If you need to get into a lab, please ask staff for assistance. Please rest assured that this issue is not unusual and happens periodically. It will likely resolve in the next couple hours. Unfortunately, there is nothing we can really do about this issue besides wait for the system to reset.
