Me moving widely among customers, I need to make on site a quantity of documents. Previously, I brought these documents physically and had to make photocopies to return (in fact it is the student who made the photocopies)
With this portable scanner (easily into a backpack for laptop 15 "laptop with said course ^^) I save documents directly on site and thus saving time and paper.
For cons, I have to find another trick to occupy the intern ...: - /
