Dual Badge Holder

I needed a way to carry multiple badges for work. Everytime I badge into the door, the RFID reader picks up a bunch of my badges and doesn't work. I end up having to take my main badge out, badge in, and put it back in. Very annoying. Most of my badges are meant for different doors, so I wanted a way to have a main badge up front for my 90% doors and the rest in the back since I don't use them nearly as often.
