Q: When I swipe my card, Pharos says "Logon ID may not be blank" or "Logon invalid"

Answer

If you receive an error that says "Logon ID may not be blank" when you swipe your card at a Pharos panel for a Pharos printer, that indicates that the magnetic stripe on your card is unreadable or that you have a very old (pre-2003) MIT ID card. In either case, you can get one at the self-service kiosk in building E17. See: Get an ID Card
