It is called RealID. Some military installations will not let you enter (if you are a civilian) unless you have one. IN CT, a yellow star is put on your driver's license. To get it, you have to go to the DMV (always a pleasure) with your existing license, certified U.S. birth certificate (NOT just a copy) or current U.S. Passport, SS card, W-2, or 1099 with SS number, & 2 proofs of residency from two different sources of the state that you live in, i.e. mortgage statement, bank statement, Medicare benefit statement, SS benefits statement dated within the last 12 months property tax bill, motor vehicle registration, and postmarked mail, among other things. Any two of these will do. Note that photocopies, notarized photocopies, and non-certified copies are not acceptable. It's not strictly enforced yet, but will be, I think, in 2017. My daughter flew to California last month from Newark, and had no problems. Hope this helps.
EDIT: But, as always, check the requirements for the state that you live in. I just supplied the documents, they scanned and stored them, took my picture, and I got the new license. I wasn't asked any questions, and it really wasn't a hassle.
