The simplest is possibly a badge or photo ID card that you show. This can be combined with a barcode or chip that is additionally scanned, which will also help to keep track of who entered and left an area and when. On top of that you can have fingerprint and/or iris scan. In our building - a research institute - every coworker has an electronic key the size of a large coin that allows you to open doors which immediately close again automatically after you have passed through. Some people have full access to all rooms in the building, others just to selected areas. There are also time-restrictions in the sense that some people can enter 24/7 while others only during normal working hours. Can be adjusted on the computer by the building administrator. For one-time deliveries it might be as simple as an authorization letter on paper. However, with the very limited number of people who pass through the Groom Lake Road gate I would not be very surprised if access control is not much beyond "known in person" ;-) I mean, if it is the same small number of people who pass there day in day out possibly little need for more sophisticated system. Is it known how long the white bus stops when "checking in"?
Generally, there are various kinds of access control.
