Although I was able to smile at them briefly, I knew that my job was to help my fellow soldiers and scan for potential threats while patrolling the province.
McDonald's and Macy's are both integrating QR codes into their hiring ads, so that job seekers or customers can walk into a store, scan the code they see on a poster, and be sent directly to the openings available at that location.
Is a probe more serious than a scan, etc.? Finally, once properly defined, those whose job it is to explain the threat to politicians and citizens should be precise in their use of these terms.
