It could have its uses
For events where a standardized and adequate picture needs to be attached at time of submission to an applicant's paperwork, this would be useful.
The biggest users of Polaroid cameras and films are, of all things, television studios. I know of several TV game shows, for instance, which, as part of their application process, snap a Polaroid pic to be attached to the applicant's test results and questionnaire at the time of the interview. From examples with which I'm familiar, these productions probably go through about six to eight packs (10 shots per pack, IIRC) per day during a typical 120-day production season.
Being able to do the same thing with digital cameras and a few of these (since there are usually several intake people working at once) the same result could be achieved.
...Just sayin' that there might be a use for something like this.
As a side note -- my daughter, a fine-art photographer, was bummed when Polariod got out of the instant-film business. She had converted a Polaroid to a pinhole camera and was getting some amazing effects with it -- the long exposures required for a pinhole camera makes very dense images with a wide tonal range that you would never expect from an instant-film camera, and each picture is truly one of a kind.
