I got my MnPASS transponder on Tuesday. I had my first opportunity to use it today on my drive into work. I hopped on the "sane-lane" at highway 100 into downtown. It only cost $0.25 so I figured I would just give it a try.
When passing under the sensor the transponder in my car beeped four times to indicate it had been recognized and I zipped on into work. I was curious to see how fast the system was so I logged onto the website when I got into work and was pretty impressed to see that my account had already been debited the appropriate amount. Very nice!
All in all, it seems like a really nice system and I like how it's being implemented.
