Comment Could Be Handy in the Gun Shop (Score 5, Interesting) 133
This could actually be useful for gun shops, since we have to meticulously catalog the serial numbers of all firearms that come in and go out. We often get older (like, 150 year older), used firearms where the serials are worn down and difficult to read, even with a jewelers loupe.
Or rather it would be useful for gun shops, if the process isn't as cost-prohibitive as I presume it will be.
