I know Norfolk Naval Station where I work does not have self scanners at the gates and I've been thru Gates 1, 2, 3A, 4, 5, 10 and 22 all in the last few months. (They have closed Gate 1 for upgrades the last few days so maybe self scanners are an upgrade.) Last month I went through Gates 1,3 and 5 at the joint base at Little Creek and there were no self scanners. During the high part of the morning rush hour - 0530 to 0800 - I can drive in and MAYBE have my CAC scanned 1 time out of 5. And it is random - i.e., I will watch a gate guard merely check the ID photo and driver and not scan the card for maybe 2-4 times, then scan two cards in a row. So even though they aren't scanning them, you don't know who they will select. However, the rest of the day they scan almost 100% of the cards. And driver's licenses - that depends on the guard. I've had to pull a co-worker's CAC out of their computer where they left it the day before and take it down to the gate because the guard will only accept a CAC or retired military ID. As far as passengers go, they only check those during security drills - about 2-3 times a year.
