My friend Dan uses the employee entrance with an automatic door and card reader access. Before the card reader was installed, he could roll up to the post and hit the foot switch with his foot rest for the door to open. Now, a card reader was installed (see the black box posted below the hand switch). His employee ID card has a microchip in it. When he rolls near the card reader, the card reader reads his card and sends the signal to the door to open. This system was installed after Dan's advocacy for accessibility. It's not hard to do, and not expensive - just takes the willingness to look at new ideas.
