Can I go to SLEX without RFID?

I'm curious, is it still possible to use SLEX without an RFID tag? I understand that RFID technology has been implemented for faster and more efficient toll transactions, but I'm wondering if there's an alternative for those who haven't gotten their RFID yet. Is there a manual lane available for those who prefer the traditional method of paying toll fees, or are there any specific requirements or procedures I need to follow if I plan to travel on SLEX without an RFID tag?
