According to Travel Weekly, TSA is already alerting travelers to upcoming ID requirements which will take effect in 2018.
These changes are part of The Real ID Act, passed by Congress in 2005. There will be Minimum security-related requirements for state-issued driver’s licenses and identification cards. The law establishes what data a state must require before issuing a license or card and what data they must subsequently store electronically. It also says what technology must be encoded in the IDs and what data must be printed on the IDs.
Right now, there are nine states that are NOT compliant. They are Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, Pennsylvania, South Carolina, and Washington. If those states don’t comply by January 22, 2018, travelers from those states will have to provide alternate ID when traveling. Accepted forms include passports, passport cards, trusted-traveler cards, and military IDs.
You can always check for more info on the TSA website.
I reported on this a while ago, but it's getting closer. After all, 2017 is just around the corner and that means 2018 is right behind it
