Here's a tip for riders who need to use a magnetic card key to access a garage gate/arm. For years, I've carried my access card in my wallet. Then I'd had to stop @ the entrance and dig out my wallet, scan it, then put my wallet away before riding up the ramp. Since I always keep my wallet in my front left pocket, I simply get close to the scanner and lift my left leg slightly. This activates the gate, without having to fumble around for my access card.
I'm so happy!
