I believe there was a government web page that listed all the forms of ID that are acceptable for TSA validation, and it specifically included Global Entry cards and Passport cards. Accordingly, I do not believe Real ID is limited to passports, state issued DL/ID cards and military ID.
Also it should be noted that travelers under the age of 18 do not need to carry Real ID for domestic flights. Earlier today my solo traveler (a minor) whipped through security with only her school ID
