The gates visible in the webcam look pretty close to the lift loading area...
As for interference and multiple RFID cards, etc...only the SB RFID card should "respond" to the RFID scanners. My understanding of RFID is that there's sort of a unique secret key that each system should be setup to use. Cards from other systems (CCs, work badges, etc) shouldn't respond to SB's scanners. If I had 2 SB passes in my pocket, then yes that would absolutely be a scenario where I could see it being confused (and where anti-collision algorithms should come into play and mitigate that factor to a degree if the system is setup to use them). The scanning system does have to walk a fine line with a big enough range to pick up the pass in a range of space on a person's body...but it can't be so large that it picks up passes from people in other lines or people behind you, etc.
We'll see how this works. I'm sure there will be some growing pains. At least most of my personal early experience should be mid-week in December when I burn my remaining vacation days for the year so no one will be around to yell at me holding up the line.
