In my schools international exchange office, we have come to the annual scan and send moment where we have to scan over a half-dozen documents and send them to our exchange agent in New Zealand, where our 90+ students will spend 6 weeks abroad this coming winter.
This year, I installed CamScanner Free on our 2 office iPads to use for this purpose. The features in the free version allows us to not only take photos of the documents to convert to PDF, but also allows us to crop them, and share with our office’s Dropbox account. Another feature is that the app allows us to save a batch of scans as a single PDF file.
Though it is still a time-consuming process, we have been able to omit a few steps between the scan and send process. It has been a viable alternative to a computer scanner.
