A few people asked me if we have a scanner here at school If you think about it all is scanner really does is take a picture of something. Most people just scan a picture or a document and save it as a .PDF or .jpg file. Granted it is pretty good resolution or quality - depending on your settings and cleanliness of the glass. This photo or document gets saved to the computer for uploading or otherwise sharing or saving digitally.
Hmm... Most of our teachers already have something that will work just fine. Their iPad.
While there are a lot of apps out there that will take a picture for you here are 2 "scanner apps" that I have used.
Takes a picture (or grab one from photos) and has simple editing tools to fix a Keystone. Save it as a different format/size such as a A3 or a business card. Then save it to Dropbox, google, Facebook... and many other sites. There are many other scanner apps out there. Just Google "ipad scanner app" Here is one page I found No, I have not used these other apps - because Docscan has served my purposes. If you like a different one please comment and share it.
Is an OCR app. Take a picture of your document then convert the image or words into editable text. Then you can save it as a Word doc to your Dropbox account! S-W-E-E-T. It is not free though. This app costs... a whopping 2.99. But it is less than a good cup of coffee! However Yes, I did get it for free via AppGratis! And YES, there are other OCR apps out there that may be better... or worse. This is the one I use and know about. Add yours to the comments.
